* Use readthedocs theme with enhancements.
* Renamed the `.txt` files to have `.rst` suffixes.
------
**Changes in Version 1.20.0**
This release uses ``MuPDF-1.20.0``, released 2022-06-15.
* Cope with new MuPDF link uri format, changed from ``#<int>,<int>,<int>`` to ``#page=<int>&zoom=<float>,<float>,<float>``.
* In ``tests/test_insertpdf.py``, use new reference output ``joined-1.20.pdf``. We also check that new output values are approximately the same as the old ones.
* **Fixed** `#1738 <https://github.com/pymupdf/PyMuPDF/issues/1738>`_. Leak of `pdf_graft_map`.
Also fixed a SEGV issue that this seemed to expose, caused by incorrect freeing of underlying fz_document.
* **Fixed** `#1733 <https://github.com/pymupdf/PyMuPDF/issues/1733>`_. Fixed ownership of `Annotation.get_pixmap()`.
Changes to build/release process:
* If pip builds from source because an appropriate wheel is not available, we no longer require MuPDF to be pre-installed. Instead the required MuPDF source is embedded in the sdist and automatically built into PyMuPDF.
* Various changes to ``setup.py`` to download the required MuPDF release as required. See comments at start of setup.py for details.
* Added ``.github/workflows/build_wheels.yml`` to control building of wheels on Github.
------
**Changes in Version 1.19.6**
* **Fixed** `#1620 <https://github.com/pymupdf/PyMuPDF/issues/1620>`_. The :ref:`TextPage` created by :meth:`Page.get_textpage` will now be freed correctly (removed memory leak).
* **Fixed** `#1601 <https://github.com/pymupdf/PyMuPDF/issues/1601>`_. Document open errors should now be more concise and easier to interpret. In the course of this, two PyMuPDF-specific Python exceptions have been **added:**
- ``EmptyFileError`` -- raised when trying to create a :ref:`Document` (``fitz.open()``) from an empty file or zero-length memory.
- ``FileDataError`` -- raised when MuPDF encounters irrecoverable document structure issues.
* **Added** :meth:`Page.load_widget` given a PDF field's xref.
* **Added** Dictionary :attr:`pdfcolor` which provide the about 500 colors defined as PDF color values with the lower case color name as key.
* **Added** algebra functionality to the :ref:`Quad` class. These objects can now also be added and subtracted among themselves, and be multiplied by numbers and matrices.
* **Added** new constants defining the default text extraction flags for more comfortable handling. Their naming convention is like :data:`TEXTFLAGS_WORDS` for ``page.get_text("words")``. See :ref:`text_extraction_flags`.
* **Changed** :meth:`Page.annots` and :meth:`Page.widgets` to detect and prevent reloading the page (illegally) inside the iterator loops via :meth:`Document.reload_page`. Doing this brings down the interpretor. Documented clean ways to do annotation and widget mass updates within properly designed loops.
* **Changed** several internal utility functions to become standalone ("SWIG inline") as opposed to be part of the :ref:`Tools` class. This, among other things, increases the performance of geometry object creation.
* **Changed** :meth:`Document.update_stream` to always accept stream updates - whether or not the dictionary object behind the xref already is a stream. Thus the former ``new`` parameter is now ignored and will be removed in v1.20.0.
------
**Changes in Version 1.19.5**
* **Fixed** `#1518 <https://github.com/pymupdf/PyMuPDF/issues/1518>`_. A limited "fix": in some cases, rectangles and quadrupels were not correctly encoded to support re-drawing by :ref:`Shape`.
* **Fixed** `#1521 <https://github.com/pymupdf/PyMuPDF/issues/1521>`_. This had the same ultimate reason behind issue #1510.
* **Fixed** `#1513 <https://github.com/pymupdf/PyMuPDF/issues/1513>`_. Some Optional Content functions did not support non-ASCII characters.
* **Fixed** `#1510 <https://github.com/pymupdf/PyMuPDF/issues/1510>`_. Support more soft-mask image subtypes.
* **Fixed** `#1507 <https://github.com/pymupdf/PyMuPDF/issues/1507>`_. Immunize against items in the outlines chain, that are ``"null"`` objects.
* **Fixed** re-opened `#1417 <https://github.com/pymupdf/PyMuPDF/issues/1417>`_. ("too many open files"). This was due to insufficient calls to MuPDF's ``fz_drop_document()``. This also fixes `#1550 <https://github.com/pymupdf/PyMuPDF/issues/1550>`_.
* **Fixed** several undocumented issues in relation to incorrectly setting the text span origin :data:`point_like`.
* **Fixed** undocumented error computing the character bbox in method :meth:`Page.get_texttrace` when text is **flipped** (as opposed to just rotated).
* **Added** items to the dictionary returned by :meth:`image_properties`: ``orientation`` and ``transform`` report the natural image orientation (EXIF data).
* **Added** method :meth:`Document.xref_copy`. It will make a given target PDF object an exact copy of a source object.
------
**Changes in Version 1.19.4**
* **Fixed** `#1505 <https://github.com/pymupdf/PyMuPDF/issues/1505>`_. Immunize against circular outline items.
* **Fixed** `#1484 <https://github.com/pymupdf/PyMuPDF/issues/1484>`_. Correct CropBox coordinates are now returned in all situations.
* **Fixed** `#1479 <https://github.com/pymupdf/PyMuPDF/issues/1479>`_.
* **Fixed** `#1474 <https://github.com/pymupdf/PyMuPDF/issues/1474>`_. TextPage objects are now properly deleted again.
* **Added** :ref:`Page` methods and attributes for PDF ``/ArtBox``, ``/BleedBox``, ``/TrimBox``.
* **Added** global attribute :attr:`TESSDATA_PREFIX` for easy checking of OCR support.
* **Changed** :meth:`Document.xref_set_key` such that dictionary keys will physically be removed if set to value ``"null"``.
* **Changed** :meth:`Document.extract_font` to optionally return a dictionary (instead of a tuple).
------
**Changes in Version 1.19.3**
This patch version implements minor improvements for :ref:`Pixmap` and also some important fixes.
* **Fixed** `#1351 <https://github.com/pymupdf/PyMuPDF/discussions/1351>`_. Reverted code that introduced the memory growth in v1.18.15.
* **Fixed** `#1417 <https://github.com/pymupdf/PyMuPDF/discussions/1417>`_. Developped circumvention for growth of open file handles using :meth:`Document.insert_pdf`.
* **Fixed** `#1418 <https://github.com/pymupdf/PyMuPDF/discussions/1418>`_. Developped circumvention for memory growth using :meth:`Document.insert_pdf`.
* **Fixed** `#1430 <https://github.com/pymupdf/PyMuPDF/discussions/1430>`_. Developped circumvention for mass pixmap generations of document pages.
* **Fixed** `#1433 <https://github.com/pymupdf/PyMuPDF/discussions/1433>`_. Solves a bbox error for some Type 3 font in PyMuPDF text processing.
* **Added** :meth:`Pixmap.color_topusage` to determine the share of the most frequently used color. Solves `#1397 <https://github.com/pymupdf/PyMuPDF/discussions/1397>`_.
* **Added** :meth:`Pixmap.warp` which makes a new pixmap from a given arbitrary convex quad inside the pixmap.
* **Added** :attr:`Annot.irt_xref` and :meth:`Annot.set_irt_xref` to inquire or set the `/IRT` ("In Responde To") property of an annotation. Implements `#1450 <https://github.com/pymupdf/PyMuPDF/discussions/1450>`_.
* **Added** :meth:`Rect.torect` and :meth:`IRect.torect` which compute a matrix that transforms to a given other rectangle.
* **Changed** :meth:`Pixmap.color_count` to also return the count of each color.
* **Changed** :meth:`Page.get_texttrace` to also return correct span and character bboxes if ``span["dir"] != (1, 0)``.
------
**Changes in Version 1.19.2**
This patch version implements minor improvements for :meth:`Page.get_drawings` and also some important fixes.
* **Fixed** `#1388 <https://github.com/pymupdf/PyMuPDF/discussions/1388>`_. Fixed intermittent memory corruption when insert or updating annotations.
* **Fixed** `#1375 <https://github.com/pymupdf/PyMuPDF/discussions/1375>`_. Inconsistencies between line numbers as returned by the "words" and the "dict" options of :meth:`Page.get_text` have been corrected.
* **Fixed** `#1364 <https://github.com/pymupdf/PyMuPDF/issues/1342>`_. The check for being a ``"rawdict"`` span in :meth:`recover_span_quad` now works correctly.
* **Fixed** `#1342 <https://github.com/pymupdf/PyMuPDF/issues/1364>`_. Corrected the check for rectangle infiniteness in :meth:`Page.show_pdf_page`.
* **Changed** :meth:`Page.get_drawings`, :meth:`Page.get_cdrawings` to return an indicator on the area orientation covered by a rectangle. This implements `#1355 <https://github.com/pymupdf/PyMuPDF/issues/1355>`_. Also, the recognition rate for rectangles and quads has been significantly improved.
* **Changed** all text search and extraction methods to set the new ``flags`` option ``TEXT_MEDIABOX_CLIP`` to ON by default. That bit causes the automatic suppression of all characters that are completely outside a page's mediabox (in as far as that notion is supported for a document type). This eliminates the need for using ``clip=page.rect`` or similar for omitting text outside the visible area.
* **Added** parameter ``"dpi"`` to :meth:`Page.get_pixmap` and :meth:`Annot.get_pixmap`. When given, parameter ``"matrix"`` is ignored, and a :ref:`Pixmap` with the desired dots per inch is created.
* **Added** attributes :attr:`Pixmap.is_monochrome` and :attr:`Pixmap.is_unicolor` allowing fast checks of pixmap properties. Addresses `#1397 <https://github.com/pymupdf/PyMuPDF/discussions/1397>`_.
* **Added** method :meth:`Pixmap.color_count` to determine the unique colors in the pixmap.
* **Added** boolean parameter ``"compress"`` to PDF document method :meth:`Document.update_stream`. Addresses / enables solution for `#1408 <https://github.com/pymupdf/PyMuPDF/discussions/1408>`_.
------
**Changes in Version 1.19.1**
This is the first patch version to support MuPDF v1.19.0. Apart from one bug fix, it includes important improvements for OCR support and the option to **sort extracted text** to the standard reading order "from top-left to bottom-right".
* **Fixed** `#1328 <https://github.com/pymupdf/PyMuPDF/issues/1328>`_. "words" text extraction again returns correct ``(x0, y0)`` coordinates.
* **Changed** :meth:`Page.get_textpage_ocr`: it now supports parameter ``dpi`` to control OCR quality. It is also possible to choose whether the **full page** should be OCRed or **only the images displayed** by the page.
* **Changed** :meth:`Page.get_drawings` and :meth:`Page.get_cdrawings` to automatically convert colors to RGB color tuples. Implements `#1332 <https://github.com/pymupdf/PyMuPDF/discussions/1332>`_. Similar change was applied to :meth:`Page.get_texttrace`.
* **Changed** :meth:`Page.get_text` to support a parameter ``sort``. If set to ``True`` the output is conveniently sorted.
------
**Changes in Version 1.19.0**
This is the first version supporting MuPDF 1.19.*, published 2021-10-05. It introduces many new features compared to the previous version 1.18.*.
PyMuPDF has now picked up integrated Tesseract OCR support, which was already present in MuPDF v1.18.0.
* Supported images can be OCRed via their :ref:`Pixmap` which results in a 1-page PDF with a text layer.
* All supported document pages (i.e. not only PDFs), can be OCRed using specialized text extraction methods. The result is a mixture of standard and OCR text (depending on which part of the page was deemed to require OCRing) that can be searched and extracted without restrictions.
* All this requires an independent installation of Tesseract. MuPDF actually (only) needs the location of Tesseract's ``"tessdata"`` folder, where its language support data are stored. This location must be available as environment variable ``TESSDATA_PREFIX``.
A new MuPDF feature is **journalling PDF updates**, which is also supported by this PyMuPDF version. Changes may be logged, rolled back or replayed, allowing to implement a whole new level of control over PDF document integrity -- similar to functions present in modern database systems.
A third feature (unrelated to the new MuPDF version) includes the ability to detect when page **objects cover or hide each other**. It is now e.g. possible to see that text is covered by a drawing or an image.
* **Changed** terminology and meaning of important geometry concepts: Rectangles are now characterized as *finite*, *valid* or *empty*, while the definitions of these terms have also changed. Rectangles specifically are now thought of being "open": not all corners and sides are considered part of the retangle. Please do read the :ref:`Rect` section for details.
* **Added** new parameter `"no_new_id"` to :meth:`Document.save` / :meth:`Document.tobytes` methods. Use it to suppress updating the second item of the document ``/ID`` which in PDF indicates that the original file has been updated. If the PDF has no ``/ID`` at all yet, then no new one will be created either.
* **Added** a **journalling facility** for PDF updates. This allows logging changes, undoing or redoing them, or saving the journal for later use. Refer to :meth:`Document.journal_enable` and friends.
* **Added** new :ref:`Pixmap` methods :meth:`Pixmap.pdfocr_save` and :meth:`Pixmap.pdfocr_tobytes`, which generate a 1-page PDF containing the pixmap as PNG image with OCR text layer.
* **Added** :meth:`Page.get_textpage_ocr` which executes optical character recognition for the page, then extracts the results and stores them together with "normal" page content in a :ref:`TextPage`. Use or reuse this object in subsequent text extractions and text searches to avoid multiple efforts. The existing text search and text extraction methods have been extended to support a separately created textpage -- see next item.
* **Added** a new parameter ``textpage`` to text extraction and text search methods. This allows reuse of a previously created :ref:`TextPage` and thus achieves significant runtime benefits -- which is especially important for the new OCR features. But "normal" text extractions can definitely also benefit.
* **Added** :meth:`Page.get_texttrace`, a technical method delivering low-level text character properties. It was present before as a private method, but the author felt it now is mature enough to be officially available. It specifically includes a "sequence number" which indicates the page appearance build operation that painted the text.
* **Added** :meth:`Page.get_bboxlog` which delivers the list of rectangles of page objects like text, images or drawings. Its significance lies in its sequence: rectangles intersecting areas with a lower index are covering or hiding them.
* **Changed** methods :meth:`Page.get_drawings` and :meth:`Page.get_cdrawings` to include a "sequence number" indicating the page appearance build operation that created the drawing.
* **Fixed** `#1311 <https://github.com/pymupdf/PyMuPDF/issues/1311>`_. Field values in comboboxes should now be handled correctly.
* **Fixed** `#1290 <https://github.com/pymupdf/PyMuPDF/issues/1290>`_. Error was caused by incorrect rectangle emptiness check, which is fixed due to new geometry logic of this version.
* **Fixed** `#1286 <https://github.com/pymupdf/PyMuPDF/issues/1286>`_. Text alignment for redact annotations is working again.
* **Fixed** `#1287 <https://github.com/pymupdf/PyMuPDF/issues/1287>`_. Infinite loop issue for non-Windows systems when applying some redactions has been resolved.
* **Fixed** `#1284 <https://github.com/pymupdf/PyMuPDF/issues/1284>`_. Text layout destruction after applying redactions in some cases has been resolved.
------
**Changes in Version 1.18.18 / 1.18.19**
* **Fixed** issue `#1266 <https://github.com/pymupdf/PyMuPDF/issues/1266>`_. Failure to set :attr:`Pixmap.samples` in important cases, was hotfixed in a new version 1.18.19.
* **Fixed** issue `#1257 <https://github.com/pymupdf/PyMuPDF/issues/1257>`_. Removing the read-only flag from PDF fields is now possible.
* **Fixed** issue `#1252 <https://github.com/pymupdf/PyMuPDF/issues/1252>`_. Now correctly specifying the ``zoom`` value for PDF link annotations.
* **Fixed** issue `#1244 <https://github.com/pymupdf/PyMuPDF/issues/1244>`_. Now correctly computing the transform matrix in :meth:`Page.get_image__bbox`.
* **Fixed** issue `#1241 <https://github.com/pymupdf/PyMuPDF/issues/1241>`_. Prevent returning artifact characters in :meth:`Page.get_textbox`, which happened in certain constellations.
* **Fixed** issue `#1234 <https://github.com/pymupdf/PyMuPDF/issues/1234>`_. Avoid creating infinite rectangles in corner cases -- :meth:`Page.get_drawings`, :meth:`Page.get_cdrawings`.
* **Added** test data and test scripts to the source PyPI source distribution.
------
**Changes in Version 1.18.17**
Focus of this version are major performance improvements of selected functions.
* **Fixed** issue `#1199 <https://github.com/pymupdf/PyMuPDF/issues/1199>`_. Using a non-existing page number in :meth:`Document.get_page_images` and friends will no longer lead to segfaults.
* **Changed** :meth:`Page.get_drawings` to now differentiate between "stroke", "fill" and combined paths. Paths containing more than one rectangle (i.e. "re" items) are now supported. Extracting "clipped" paths is now available as an option.
* **Added** :meth:`Page.get_cdrawings`, performance-optimized version of :meth:`Page.get_drawings`.
* **Added** :attr:`Pixmap.samples_mv`, *memoryview* of a pixmap's pixel area. Does not copy and thus always accesses the current state of that area.
* **Added** :attr:`Pixmap.samples_ptr`, Python "pointer" to a pixmap's pixel area. Allows much faster creation (factor 800+) of Qt images.
------
**Changes in Version 1.18.16**
* **Fixed** issue `#1184 <https://github.com/pymupdf/PyMuPDF/issues/1184>`_. Existing PDF widget fonts in a PDF are now accepted (i.e. not forcedly changed to a Base-14 font).
* **Fixed** issue `#1154 <https://github.com/pymupdf/PyMuPDF/issues/1154>`_. Text search hits should now be correct when ``clip`` is specified.
* **Fixed** issue `#1152 <https://github.com/pymupdf/PyMuPDF/issues/1152>`_.
* **Fixed** issue `#1146 <https://github.com/pymupdf/PyMuPDF/issues/1146>`_.
* **Added** :attr:`Link.flags` and :meth:`Link.set_flags` to the :ref:`Link` class. Implements enhancement requests `#1187 <https://github.com/pymupdf/PyMuPDF/issues/1187>`_.
* **Added** option to *simulate* :meth:`TextWriter.fill_textbox` output for predicting the number of lines, that a given text would occupy in the textbox.
* **Added** text output support as subcommand `gettext` to the ``fitz`` CLI module. Most importantly, original **physical text layout** reproduction is now supported.
------
**Changes in Version 1.18.15**
* **Fixed** issue `#1088 <https://github.com/pymupdf/PyMuPDF/issues/1088>`_. Removing an annotation's fill color should now work again both ways, using the ``fill_color=[]`` argument in :meth:`Annot.update` as well as ``fill=[]`` in :meth:`Annot.set_colors`.
* **Fixed** issue `#1081 <https://github.com/pymupdf/PyMuPDF/issues/1081>`_. :meth:`Document.subset_fonts`: fixed an error which created wrong character widths for some fonts.
* **Fixed** issue `#1078 <https://github.com/pymupdf/PyMuPDF/issues/1078>`_. :meth:`Page.get_text` and other methods related to text extraction: changed the default value of the :ref:`TextPage` ``flags`` parameter. All whitespace and :data:`ligatures` are now preserved.
* **Fixed** issue `#1085 <https://github.com/pymupdf/PyMuPDF/issues/1085>`_. The old *snake_cased* alias of ``fitz.detTextlength`` is now defined correctly.
* **Changed** :meth:`Document.subset_fonts` will now correctly prefix font subsets with an appropriate six letter uppercase tag, complying with the PDF specification.
* **Added** new method :meth:`Widget.button_states` which returns the possible values that a button-type field can have when being set to "on" or "off".
* **Added** support of text with **Small Capital** letters to the :ref:`Font` and :ref:`TextWriter` classes. This is reflected by an additional bool parameter ``small_caps`` in various of their methods.
------
**Changes in Version 1.18.14**
* **Finished** implementing new, "snake_cased" names for methods and properties, that were "camelCased" and awkward in many aspects. At the end of this documentation, there is section :ref:`Deprecated` with more background and a mapping of old to new names.
* **Fixed** issue `#1053 <https://github.com/pymupdf/PyMuPDF/issues/1053>`_. :meth:`Page.insert_image`: when given, include image mask in the hash computation.
* **Fixed** issue `#1043 <https://github.com/pymupdf/PyMuPDF/issues/1043>`_. Added ``Pixmap.getPNGdata`` to the aliases of :meth:`Pixmap.tobytes`.
* **Fixed** an internal error when computing the envelopping rectangle of drawn paths as returned by :meth:`Page.get_drawings`.
* **Fixed** an internal error occasionally causing loops when outputting text via :meth:`TextWriter.fill_textbox`.
* **Added** :meth:`Font.char_lengths`, which returns a tuple of character widths of a string.
* **Added** more ways to specify pages in :meth:`Document.delete_pages`. Now a sequence (list, tuple or range) can be specified, and the Python ``del`` statement can be used. In the latter case, Python ``slices`` are also accepted.
* **Changed** :meth:`Document.del_toc_item`, which disables a single item of the TOC: previously, the title text was removed. Instead, now the complete item will be shown grayed-out by supporting viewers.
------
**Changes in Version 1.18.13**
* **Fixed** issue `#1014 <https://github.com/pymupdf/PyMuPDF/issues/1014>`_.
* **Fixed** an internal memory leak when computing image bboxes -- :meth:`Page.get_image_bbox`.
* **Added** support for low-level access and modification of the PDF trailer. Applies to :meth:`Document.xref_get_keys`, :meth:`Document.xref_get_key`, and :meth:`Document.xref_set_key`.
* **Added** documentation for maintaining private entries in PDF metadata.
* **Added** documentation for handling transparent image insertions, :meth:`Page.insert_image`.
* **Added** :meth:`Page.get_image_rects`, an improved version of :meth:`Page.get_image_bbox`.
* **Changed** :meth:`Document.delete_pages` to support various ways of specifying pages to delete. Implements `#1042 <https://github.com/pymupdf/PyMuPDF/issues/1042>`_.
* **Changed** :meth:`Page.insert_image` to also accept the xref of an existing image in the file. This allows "copying" images between pages, and extremely fast mutiple insertions.
* **Changed** :meth:`Page.insert_image` to also accept the integer parameter ``alpha``. To be used for performance improvements.
* **Changed** :meth:`Pixmap.set_alpha` to support new parameters for pre-multiplying colors with their alpha values and setting a specific color to fully transparent (e.g. white).
* **Changed** :meth:`Document.embfile_add` to automatically set creation and modification date-time. Correspondingly, :meth:`Document.embfile_upd` automatically maintains modification date-time (``/ModDate`` PDF key), and :meth:`Document.embfile_info` correspondingly reports these data. In addition, the embedded file's associated "collection item" is included via its :data:`xref`. This supports the development of PDF portfolio applications.
------
**Changes in Version 1.18.11 / 1.18.12**
* **Fixed** issue `#972 <https://github.com/pymupdf/PyMuPDF/issues/972>`_. Improved layout of source distribution material.
* **Fixed** issue `#962 <https://github.com/pymupdf/PyMuPDF/issues/962>`_. Stabilized Linux distribution detection for generating PyMuPDF from sources.
* **Added:** :meth:`Page.get_xobjects` delivers the result of :meth:`Document.get_page_xobjects`.
* **Added:** :meth:`Page.get_image_info` delivers meta information for all images shown on the page.
* **Added:** :meth:`Tools.mupdf_display_warnings` allows setting on / off the display of MuPDF-generated warnings. The default is off.
* **Added:** :meth:`Document.ez_save` convenience alias of :meth:`Document.save` with some different defaults.
* **Changed:** Image extractions of document pages now also contain the image's **transformation matrix**. This concerns :meth:`Page.get_image_bbox` and the DICT, JSON, RAWDICT, and RAWJSON variants of :meth:`Page.get_text`.
------
**Changes in Version 1.18.10**
* **Fixed** issue `#941 <https://github.com/pymupdf/PyMuPDF/issues/941>`_. Added old aliases for :meth:`DisplayList.get_pixmap` and :meth:`DisplayList.get_textpage`.
* **Fixed** issue `#929 <https://github.com/pymupdf/PyMuPDF/issues/929>`_. Stabilized removal of JavaScript objects with :meth:`Document.scrub`.
* **Fixed** issue `#927 <https://github.com/pymupdf/PyMuPDF/issues/927>`_. Removed a loop in the reworked :meth:`TextWriter.fill_textbox`.
* **Changed** :meth:`Document.xref_get_keys` and :meth:`Document.xref_get_key` to also allow accessing the PDF trailer dictionary. This can be done by using `-1` as the xref number argument.
* **Added** a number of functions for reconstructing the quads for text lines, spans and characters extracted by :meth:`Page.get_text` options "dict" and "rawdict". See :meth:`recover_quad` and friends.
* **Added** :meth:`Tools.unset_quad_corrections` to suppress character quad corrections (occasionally required for erroneous fonts).
------
**Changes in Version 1.18.9**
* **Fixed** issue `#888 <https://github.com/pymupdf/PyMuPDF/issues/888>`_. Removed ambiguous statements concerning PyMuPDF's license, which is now clearly stated to be GNU AGPL V3.
* **Fixed** issue `#895 <https://github.com/pymupdf/PyMuPDF/issues/895>`_.
* **Fixed** issue `#896 <https://github.com/pymupdf/PyMuPDF/issues/896>`_. Since v1.17.6 PyMuPDF suppresses the font subset tags and only reports the base fontname in text extraction outputs "dict" / "json" / "rawdict" / "rawjson". Now a new global parameter can request the old behaviour, :meth:`Tools.set_subset_fontnames`.
* **Fixed** issue `#885 <https://github.com/pymupdf/PyMuPDF/issues/885>`_. Pixmap creation now also works with filenames given as ``pathlib.Paths``.
* **Changed** :meth:`Document.subset_fonts`: Text is **not rewritten** any more and should therefore **retain all its origial properties** -- like being hidden or being controlled by Optional Content mechanisms.
* **Changed** :ref:`TextWriter` output to also accept text in right to left mode (Arabian, Hebrew): :meth:`TextWriter.fill_textbox`, :meth:`TextWriter.append`. These methods now accept a new boolean parameter `right_to_left`, which is *False* by default. Implements `#897 <https://github.com/pymupdf/PyMuPDF/issues/897>`_.
* **Changed** :meth:`TextWriter.fill_textbox` to return all lines of text, that did not fit in the given rectangle. Also changed the default of the ``warn`` parameter to no longer print a warning message in overflow situations.
* **Added** a utility function :meth:`recover_quad`, which computes the quadrilateral of a span. This function can be used for correctly marking text extracted with the "dict" or "rawdict" options of :meth:`Page.get_text`.
------
**Changes in Version 1.18.8**
This is a bug fix version only. We are publishing early because of the potentially widely used functions.
* **Fixed** issue `#881 <https://github.com/pymupdf/PyMuPDF/issues/881>`_. Fixed a memory leak in :meth:`Page.insert_image` when inserting images from files or memory.
* **Fixed** issue `#878 <https://github.com/pymupdf/PyMuPDF/issues/878>`_. ``pathlib.Path`` objects should now correctly handle file path hierarchies.
------
**Changes in Version 1.18.7**
* **Added** an experimental :meth:`Document.subset_fonts` which reduces the size of eligible fonts based on their use by text in the PDF. Implements `#855 <https://github.com/pymupdf/PyMuPDF/discussions/855>`_.
* **Implemented** request `#870 <https://github.com/pymupdf/PyMuPDF/pull/870>`_: :meth:`Document.convert_to_pdf` now also supports PDF documents.
* **Renamed** ``Document.write`` to :meth:`Document.tobytes` for greater clarity. But the deprecated name remains available for some time.
* **Implemented** request `#843 <https://github.com/pymupdf/PyMuPDF/Discussions/843>`_: :meth:`Document.tobytes` now supports linearized PDF output. :meth:`Document.save` now also supports writing to Python **file objects**. In addition, the open function now also supports Python file objects.
* **Fixed** issue `#844 <https://github.com/pymupdf/PyMuPDF/issues/844>`_.
* **Fixed** issue `#838 <https://github.com/pymupdf/PyMuPDF/issues/838>`_.
* **Fixed** issue `#823 <https://github.com/pymupdf/PyMuPDF/issues/823>`_. More logic for better support of OCRed text output (Tesseract, ABBYY).
* **Fixed** issue `#818 <https://github.com/pymupdf/PyMuPDF/issues/818>`_.
* **Fixed** issue `#814 <https://github.com/pymupdf/PyMuPDF/issues/814>`_.
* **Added** :meth:`Document.get_page_labels` which returns a list of page label definitions of a PDF.
* **Added** :meth:`Document.has_annots` and :meth:`Document.has_links` to check whether these object types are present anywhere in a PDF.
* **Added** expert low-level functions to simplify inquiry and modification of PDF object sources: :meth:`Document.xref_get_keys` lists the keys of object :data:`xref`, :meth:`Document.xref_get_key` returns type and content of a key, and :meth:`Document.xref_set_key` modifies the key's value.
* **Added** parameter ``thumbnails`` to :meth:`Document.scrub` to also allow removing page thumbnail images.
* **Improved** documentation for how to add valid text marker annotations for non-horizontal text.
We continued the process of renaming methods and properties from *"mixedCase"* to *"snake_case"*. Documentation usually mentions the new names only, but old, deprecated names remain available for some time.
------
**Changes in Version 1.18.6**
* **Fixed** issue `#812 <https://github.com/pymupdf/PyMuPDF/issues/812>`_.
* **Fixed** issue `#793 <https://github.com/pymupdf/PyMuPDF/issues/793>`_. Invalid document metadata previously prevented opening some documents at all. This error has been removed.
* **Fixed** issue `#792 <https://github.com/pymupdf/PyMuPDF/issues/792>`_. Text search and text extraction will make no rectangle containment checks at all if the default ``clip=None`` is used.
* **Fixed** issue `#785 <https://github.com/pymupdf/PyMuPDF/issues/785>`_.
* **Fixed** issue `#780 <https://github.com/pymupdf/PyMuPDF/issues/780>`_. Corrected a parameter check error.
* **Fixed** issue `#779 <https://github.com/pymupdf/PyMuPDF/issues/779>`_. Fixed typo
* **Added** an option to set the desired line height for text boxes. Implements `#804 <https://github.com/pymupdf/PyMuPDF/issues/804>`_.
* **Changed** text position retrieval to better cope with Tesseract's glyphless font. Implements `#803 <https://github.com/pymupdf/PyMuPDF/issues/803>`_.
* **Added** an option to choose the prefix of new annotations, fields and links for providing unique annotation ids. Implements request `#807 <https://github.com/pymupdf/PyMuPDF/issues/807>`_.
* **Added** getting and setting color and text properties for Table of Contents items for PDFs. Implements `#779 <https://github.com/pymupdf/PyMuPDF/issues/779>`_.
* **Added** PDF page label handling: :meth:`Page.get_label()` returns the page label, :meth:`Document.get_page_numbers` return all page numbers having a specified label, and :meth:`Document.set_page_labels` adds or updates a PDF's page label definition.
.. note::
This version introduces **Python type hinting**. The goal is to provide each parameter and the return value of all functions and methods with type information. This still is work in progress although the majority of functions has already been handled.
------
**Changes in Version 1.18.5**
Apart from several fixes, this version also focusses on several minor, but important feature improvements. Among the latter is a more precise computation of proper line heights and insertion points for writing / inserting text. As opposed to using font-agnostic constants, these values are now taken from the font's properties.
Also note that this is the first version which does no longer provide pregenerated wheels for Python versions older than 3.6. PIP also discontinues support for these by end of this year 2020.
* **Fixed** issue `#771 <https://github.com/pymupdf/PyMuPDF/issues/771>`_. By using "small glyph heights" option, the full page text can be extracted.
* **Fixed** issue `#768 <https://github.com/pymupdf/PyMuPDF/issues/768>`_.
* **Fixed** issue `#750 <https://github.com/pymupdf/PyMuPDF/issues/750>`_.
* **Fixed** issue `#739 <https://github.com/pymupdf/PyMuPDF/issues/739>`_. The "dict", "rawdict" and corresponding JSON output variants now have two new *span* keys: ``"ascender"`` and ``"descender"``. These floats represent special font properties which can be used to compute bboxes of spans or characters of **exactly fontsize height** (as opposed to the default line height). An example algorithm is shown in section "Span Dictionary" `here <https://pymupdf.readthedocs.io/en/latest/textpage.html#dictionary-structure-of-extractdict-and-extractrawdict>`_. Also improved the detection and correction of ill-specified ascender / descender values encountered in some fonts.
* **Added** a new, experimental :meth:`Tools.set_small_glyph_heights` -- also in response to issue `#739 <https://github.com/pymupdf/PyMuPDF/issues/739>`_. This method sets or unsets a global parameter to **always compute bboxes with fontsize height**. If "on", text searching and all text extractions will returned rectangles, bboxes and quads with a smaller height.
* **Fixed** issue `#728 <https://github.com/pymupdf/PyMuPDF/issues/728>`_.
* **Changed** fill color logic of 'Polyline' annotations: this parameter now only pertains to line end symbols -- the annotation itself can no longer have a fill color. Also addresses issue `#727 <https://github.com/pymupdf/PyMuPDF/issues/727>`_.
* **Changed** :meth:`Page.getImageBbox` to also compute the bbox if the image is contained in an XObject.
* **Changed** :meth:`Shape.insertTextbox`, resp. :meth:`Page.insertTextbox`, resp. :meth:`TextWriter.fillTextbox` to respect font's properties "ascender" / "descender" when computing line height and insertion point. This should no longer lead to line overlaps for multi-line output. These methods used to ignore font specifics and used constant values instead.
------
**Changes in Version 1.18.4**
This version adds several features to support PDF Optional Content. Among other things, this includes OCMDs (Optional Content Membership Dictionaries) with the full scope of *"visibility expressions"* (PDF key ``/VE``), text insertions (including the :ref:`TextWriter` class) and drawings.
* **Fixed** issue `#727 <https://github.com/pymupdf/PyMuPDF/issues/727>`_. Freetext annotations now support an uncolored rectangle when ``fill_color=None``.
* **Fixed** issue `#726 <https://github.com/pymupdf/PyMuPDF/issues/726>`_. UTF-8 encoding errors are now handled for HTML / XML :meth:`Page.getText` output.
* **Fixed** issue `#724 <https://github.com/pymupdf/PyMuPDF/issues/724>`_. Empty values are no longer stored in the PDF /Info metadata dictionary.
* **Added** new methods :meth:`Document.set_oc` and :meth:`Document.get_oc` to set or get optional content references for **existing** image and form XObjects. These methods are similar to the same-named methods of :ref:`Annot`.
* **Added** :meth:`Document.set_ocmd`, :meth:`Document.get_ocmd` for handling OCMDs.
* **Added** **Optional Content** support for text insertion and drawing.
* **Added** new method :meth:`Page.deleteWidget`, which deletes a form field from a page. This is analogous to deleting annotations.
* **Added** support for Popup annotations. This includes defining the Popup rectangle and setting the Popup to open or closed. Methods / attributes :meth:`Annot.set_popup`, :meth:`Annot.set_open`, :attr:`Annot.has_popup`, :attr:`Annot.is_open`, :attr:`Annot.popup_rect`, :attr:`Annot.popup_xref`.
Other changes:
* The **naming of methods and attributes** in PyMuPDF is far from being satisfactory: we have *CamelCases*, *mixedCases* and *lower_case_with_underscores* all over the place. With the :ref:`Annot` as the first candidate, we have started an activity to clean this up step by step, converting to lower case with underscores for methods and attributes while keeping UPPERCASE for the constants.
- Old names will remain available to prevent code breaks, but they will no longer be mentioned in the documentation.
- New methods and attributes of all classes will be named according to the new standard.
------
**Changes in Version 1.18.3**
As a major new feature, this version introduces support for PDF's **Optional Content** concept.
* **Fixed** issue `#714 <https://github.com/pymupdf/PyMuPDF/issues/714>`_.
* **Fixed** issue `#711 <https://github.com/pymupdf/PyMuPDF/issues/711>`_.
* **Fixed** issue `#707 <https://github.com/pymupdf/PyMuPDF/issues/707>`_: if a PDF user password, but no owner password is supplied nor present, then the user password is also used as the owner password.
* **Fixed** ``expand`` and ``deflate`` parameters of methods :meth:`Document.save` and :meth:`Document.write`. Individual image and font compression should now finally work. Addresses issue `#713 <https://github.com/pymupdf/PyMuPDF/issues/713>`_.
* **Added** a support of PDF optional content. This includes several new :ref:`Document` methods for inquiring and setting optional content status and adding optional content configurations and groups. In addition, images, form XObjects and annotations now can be bound to optional content specifications. **Resolved** issue `#709 <https://github.com/pymupdf/PyMuPDF/issues/709>`_.
------
**Changes in Version 1.18.2**
This version contains some interesting improvements for text searching: any number of search hits is now returned and the **hit_max** parameter was removed. The new **clip** parameter in addition allows to restrict the search area. Searching now detects hyphenations at line breaks and accordingly finds hyphenated words.
* **Fixed** issue `#575 <https://github.com/pymupdf/PyMuPDF/issues/575>`_: if using ``quads=False`` in text searching, then overlapping rectangles on the same line are joined. Previously, parts of the search string, which belonged to different "marked content" items, each generated their own rectangle -- just as if occurring on separate lines.
* **Added** :attr:`Document.isRepaired`, which is true if the PDF was repaired on open.
* **Added** :meth:`Document.setXmlMetadata` which either updates or creates PDF XML metadata. Implements issue `#691 <https://github.com/pymupdf/PyMuPDF/issues/691>`_.
* **Added** :meth:`Document.getXmlMetadata` returns PDF XML metadata.
* **Changed** creation of PDF documents: they will now always carry a PDF identification (``/ID`` field) in the document trailer. Implements issue `#691 <https://github.com/pymupdf/PyMuPDF/issues/691>`_.
* **Changed** :meth:`Page.searchFor`: a new parameter ``clip`` is accepted to restrict the search to this rectangle. Correspondingly, the attribute :attr:`TextPage.rect` is now respected by :meth:`TextPage.search`.
* **Changed** parameter ``hit_max`` in :meth:`Page.searchFor` and :meth:`TextPage.search` is now obsolete: methods will return all hits.
* **Changed** character **selection criteria** in :meth:`Page.getText`: a character is now considered to be part of a ``clip`` if its bbox is fully contained. Before this, a non-empty intersection was sufficient.
* **Changed** :meth:`Document.scrub` to support a new option `redact_images`. This addresses issue `#697 <https://github.com/pymupdf/PyMuPDF/issues/697>`_.
------
**Changes in Version 1.18.1**
* **Fixed** issue `#692 <https://github.com/pymupdf/PyMuPDF/issues/692>`_. PyMuPDF now detects and recovers from more cyclic resource dependencies in PDF pages and for the first time reports them in the MuPDF warnings store.
* **Fixed** issue `#686 <https://github.com/pymupdf/PyMuPDF/issues/686>`_.
* **Added** opacity options for the :ref:`Shape` class: Stroke and fill colors can now be set to some transparency value. This means that all :ref:`Page` draw methods, methods :meth:`Page.insertText`, :meth:`Page.insertTextbox`, :meth:`Shape.finish`, :meth:`Shape.insertText`, and :meth:`Shape.insertTextbox` support two new parameters: *stroke_opacity* and *fill_opacity*.
* **Added** new parameter ``mask`` to :meth:`Page.insertImage` for optionally providing an external image mask. Resolves issue `#685 <https://github.com/pymupdf/PyMuPDF/issues/685>`_.
* **Added** :meth:`Annot.soundGet` for extracting the sound of an audio annotation.
------
**Changes in Version 1.18.0**
This is the first PyMuPDF version supporting MuPDF v1.18. The focus here is on extending PyMuPDF's own functionality -- apart from bug fixing. Subsequent PyMuPDF patches may address features new in MuPDF.
* **Fixed** issue `#519 <https://github.com/pymupdf/PyMuPDF/issues/519>`_. This upstream bug occurred occasionally for some pages only and seems to be fixed now: page layout should no longer be ruined in these cases.
* **Fixed** issue `#675 <https://github.com/pymupdf/PyMuPDF/issues/675>`_.
- Unsuccessful storage allocations should now always lead to exceptions (circumvention of an upstream bug intermittently crashing the interpreter).
- :ref:`Pixmap` size is now based on ``size_t`` instead of ``int`` in C and should be correct even for extremely large pixmaps.
* **Fixed** issue `#668 <https://github.com/pymupdf/PyMuPDF/issues/668>`_. Specification of dashes for PDF drawing insertion should now correctly reflect the PDF spec.
* **Fixed** issue `#669 <https://github.com/pymupdf/PyMuPDF/issues/669>`_. A major source of memory leakage in :meth:`Page.insert_pdf` has been removed.
* **Added** keyword *"images"* to :meth:`Page.apply_redactions` for fine-controlling the handling of images.
* **Added** :meth:`Annot.getText` and :meth:`Annot.getTextbox`, which offer the same functionality as the :ref:`Page` versions.
* **Added** key *"number"* to the block dictionaries of :meth:`Page.getText` / :meth:`Annot.getText` for options "dict" and "rawdict".
* **Added** :meth:`glyph_name_to_unicode` and :meth:`unicode_to_glyph_name`. Both functions do not really connect to a specific font and are now independently available, too. The data are now based on the `Adobe Glyph List <https://github.com/adobe-type-tools/agl-aglfn/blob/master/glyphlist.txt>`_.
* **Added** convenience functions :meth:`adobe_glyph_names` and :meth:`adobe_glyph_unicodes` which return the respective available data.
* **Added** :meth:`Page.getDrawings` which returns details of drawing operations on a document page. Works for all document types.
* Improved performance of :meth:`Document.insert_pdf`. Multiple object copies are now also suppressed across multiple separate insertions from the same source. This saves time, memory and target file size. Previously this mechanism was only active within each single method execution. The feature can also be suppressed with the new method bool parameter *final=1*, which is the default.
* For PNG images created from pixmaps, the resolution (dpi) is now automatically set from the respective :attr:`Pixmap.xres` and :attr:`Pixmap.yres` values.
------
**Changes in Version 1.17.7**
* **Fixed** issue `#651 <https://github.com/pymupdf/PyMuPDF/issues/651>`_. An upstream bug causing interpreter crashes in corner case redaction processings was fixed by backporting MuPDF changes from their development repo.
* **Fixed** issue `#645 <https://github.com/pymupdf/PyMuPDF/issues/645>`_. Pixmap top-left coordinates can be set (again) by their own method, :meth:`Pixmap.set_origin`.
* **Fixed** issue `#622 <https://github.com/pymupdf/PyMuPDF/issues/622>`_. :meth:`Page.insertImage` again accepts a :data:`rect_like` parameter.
* **Added** severeal new methods to improve and speed-up table of contents (TOC) handling. Among other things, TOC items can now changed or deleted individually -- without always replacing the complete TOC. Furthermore, access to some PDF page attributes is now possible without first **loading** the page. This has a very significant impact on the performance of TOC manipulation.
* **Added** an option to :meth:`Document.insert_pdf` which allows displaying progress messages. Adresses `#640 <https://github.com/pymupdf/PyMuPDF/issues/640>`_.
* **Added** :meth:`Page.getTextbox` which extracts text contained in a rectangle. In many cases, this should obsolete writing your own script for this type of thing.
* **Added** new ``clip`` parameter to :meth:`Page.getText` to simplify and speed up text extraction of page sub areas.
* **Added** :meth:`TextWriter.appendv` to add text in **vertical write mode**. Addresses issue `#653 <https://github.com/pymupdf/PyMuPDF/issues/653>`_
------
**Changes in Version 1.17.6**
* **Fixed** issue `#605 <https://github.com/pymupdf/PyMuPDF/issues/605>`_
* **Fixed** issue `#600 <https://github.com/pymupdf/PyMuPDF/issues/600>`_ -- text should now be correctly positioned also for pages with a CropBox smaller than MediaBox.
* **Added** text span dictionary key ``origin`` which contains the lower left coordinate of the first character in that span.
* **Added** attribute :attr:`Font.buffer`, a *bytes* copy of the font file.
* **Added** parameter *sanitize* to :meth:`Page.cleanContents`. Allows switching of sanitization, so only syntax cleaning will be done.
------
**Changes in Version 1.17.5**
* **Fixed** issue `#561 <https://github.com/pymupdf/PyMuPDF/issues/561>`_ -- second go: certain :ref:`TextWriter` usages with many alternating fonts did not work correctly.
* **Fixed** issue `#566 <https://github.com/pymupdf/PyMuPDF/issues/566>`_.
* **Fixed** issue `#568 <https://github.com/pymupdf/PyMuPDF/issues/568>`_.
* **Fixed** -- opacity is now correctly taken from the :ref:`TextWriter` object, if not given in :meth:`TextWriter.writeText`.
* **Added** a new global attribute :attr:`fitz_fontdescriptors`. Contains information about usable fonts from repository `pymupdf-fonts <https://github.com/pymupdf/pymupdf-fonts>`_.
* **Added** :meth:`Font.valid_codepoints` which returns an array of unicode codepoints for which the font has a glyph.
* **Added** option ``text_as_path`` to :meth:`Page.getSVGimage`. this implements `#580 <https://github.com/pymupdf/PyMuPDF/issues/580>`_. Generates much smaller SVG files with parseable text if set to *False*.
------
**Changes in Version 1.17.4**
* **Fixed** issue `#561 <https://github.com/pymupdf/PyMuPDF/issues/561>`_. Handling of more than 10 :ref:`Font` objects on one page should now work correctly.
* **Fixed** issue `#562 <https://github.com/pymupdf/PyMuPDF/issues/562>`_. Annotation pixmaps are no longer derived from the page pixmap, thus avoiding unintended inclusion of page content.
* **Fixed** issue `#559 <https://github.com/pymupdf/PyMuPDF/issues/559>`_. This **MuPDF** bug is being temporarily fixed with a pre-version of MuPDF's next release.
* **Added** utility function :meth:`repair_mono_font` for correcting displayed character spacing for some mono-spaced fonts.
* **Added** utility method :meth:`Document.need_appearances` for fine-controlling Form PDF behavior. Addresses issue `#563 <https://github.com/pymupdf/PyMuPDF/issues/563>`_.
* **Added** utility function :meth:`sRGB_to_pdf` to recover the PDF color triple for a given color integer in sRGB format.
* **Added** utility function :meth:`sRGB_to_rgb` to recover the (R, G, B) color triple for a given color integer in sRGB format.
* **Added** utility function :meth:`make_table` which delivers table cells for a given rectangle and desired numbers of columns and rows.
* **Added** support for optional fonts in repository `pymupdf-fonts <https://github.com/pymupdf/pymupdf-fonts>`_.
------
**Changes in Version 1.17.3**
* **Fixed** an undocumented issue, which prevented fully cleaning a PDF page when using :meth:`Page.cleanContents`.
* **Fixed** issue `#540 <https://github.com/pymupdf/PyMuPDF/issues/540>`_. Text extraction for EPUB should again work correctly.
* **Fixed** issue `#548 <https://github.com/pymupdf/PyMuPDF/issues/548>`_. Documentation now includes ``LINK_NAMED``.
* **Added** new parameter to control start of text in :meth:`TextWriter.fillTextbox`. Implements `#549 <https://github.com/pymupdf/PyMuPDF/issues/549>`_.
* **Changed** documentation of :meth:`Page.add_redact_annot` to explain the usage of non-builtin fonts.
------
**Changes in Version 1.17.2**
* **Fixed** issue `#533 <https://github.com/pymupdf/PyMuPDF/issues/533>`_.
* **Added** options to modify 'Redact' annotation appearance. Implements `#535 <https://github.com/pymupdf/PyMuPDF/issues/535>`_.
------
**Changes in Version 1.17.1**
* **Fixed** issue `#520 <https://github.com/pymupdf/PyMuPDF/issues/520>`_.
* **Fixed** issue `#525 <https://github.com/pymupdf/PyMuPDF/issues/525>`_. Vertices for 'Ink' annots should now be correct.
* **Fixed** issue `#524 <https://github.com/pymupdf/PyMuPDF/issues/524>`_. It is now possible to query and set rotation for applicable annotation types.
Also significantly improved inline documentation for better support of interactive help.
------
**Changes in Version 1.17.0**
This version is based on MuPDF v1.17. Following are highlights of new and changed features:
* **Added** extended language support for annotations and widgets: a mixture of Latin, Greece, Russian, Chinese, Japanese and Korean characters can now be used in 'FreeText' annotations and text widgets. No special arrangement is required to use it.
* Faster page access is implemented for documents supporting a "chapter" structure. This applies to EPUB documents currently. This comes with several new :ref:`Document` methods and changes for :meth:`Document.loadPage` and the "indexed" page access *doc[n]*: In addition to specifying a page number as before, a tuple *(chaper, pno)* can be specified to identify the desired page.
* **Changed:** Improved support of redaction annotations: images overlapped by redactions are **permanantly modified** by erasing the overlap areas. Also links are removed if overlapped by redactions. This is now fully in sync with PDF specifications.
Other changes:
* **Changed** :meth:`TextWriter.writeText` to support the *"morph"* parameter.
* **Added** methods :meth:`Rect.morph`, :meth:`IRect.morph`, and :meth:`Quad.morph`, which return a new :ref:`Quad`.
* **Changed** :meth:`Page.add_freetext_annot` to support text alignment via a new *"align"* parameter.
* **Fixed** issue `#508 <https://github.com/pymupdf/PyMuPDF/issues/508>`_. Improved image rectangle calculation to hopefully deliver correct values in most if not all cases.
* **Fixed** issue `#502 <https://github.com/pymupdf/PyMuPDF/issues/502>`_.
* **Fixed** issue `#500 <https://github.com/pymupdf/PyMuPDF/issues/500>`_. :meth:`Document.convertToPDF` should no longer cause memory leaks.
* **Fixed** issue `#496 <https://github.com/pymupdf/PyMuPDF/issues/496>`_. Annotations and widgets / fields are now added or modified using the coordinates of the **unrotated page**. This behavior is now in sync with other methods modifying PDF pages.
* **Added** :attr:`Page.rotationMatrix` and :attr:`Page.derotationMatrix` to support coordinate transformations between the rotated and the original versions of a PDF page.
Potential code breaking changes:
* The private method ``Page._getTransformation()`` has been removed. Use the public :attr:`Page.transformationMattrix` instead.
------
**Changes in Version 1.16.18**
This version introduces several new features around PDF text output. The motivation is to simplify this task, while at the same time offering extending features.
One major achievement is using MuPDF's capabilities to dynamically choosing fallback fonts whenever a character cannot be found in the current one. This seemlessly works for Base-14 fonts in combination with CJK fonts (China, Japan, Korea). So a text may contain **any combination of characters** from the Latin, Greek, Russian, Chinese, Japanese and Korean languages.
* **Fixed** issue `#493 <https://github.com/pymupdf/PyMuPDF/issues/493>`_. ``Pixmap(doc, xref)`` should now again correctly resemble the loaded image object.
* **Fixed** issue `#488 <https://github.com/pymupdf/PyMuPDF/issues/488>`_. Widget names are now modifyable.
* **Added** new class :ref:`Font` which represents a font.
* **Added** new class :ref:`TextWriter` which serves as a container for text to be written on a page.
* **Added** :meth:`Page.writeText` to write one or more :ref:`TextWriter` objects to the page.
------
**Changes in Version 1.16.17**
* **Fixed** issue `#479 <https://github.com/pymupdf/PyMuPDF/issues/479>`_. PyMuPDF should now more correctly report image resolutions. This applies to both, images (either from images files or extracted from PDF documents) and pixmaps created from images.
* **Added** :meth:`Pixmap.set_dpi` which sets the image resolution in x and y directions.
------
**Changes in Version 1.16.16**
* **Fixed** issue `#477 <https://github.com/pymupdf/PyMuPDF/issues/477>`_.
* **Fixed** issue `#476 <https://github.com/pymupdf/PyMuPDF/issues/476>`_.
* **Changed** annotation line end symbol coloring and fixed an error coloring the interior of 'Polyline' /'Polygon' annotations.
------
**Changes in Version 1.16.14**
* **Changed** text marker annotations to accept parameters beyond just quadrilaterals such that now **text lines between two given points can be marked**.
* **Added** :meth:`Document.scrub` which **removes potentially sensitive data** from a PDF. Implements `#453 <https://github.com/pymupdf/PyMuPDF/issues/453>`_.
* **Added** :meth:`Annot.blendMode` which returns the **blend mode** of annotations.
* **Added** :meth:`Annot.setBlendMode` to set the annotation's blend mode. This resolves issue `#416 <https://github.com/pymupdf/PyMuPDF/issues/416>`_.
* **Changed** :meth:`Annot.update` to accept additional parameters for setting blend mode and opacity.
* **Added** advanced graphics features to **control the anti-aliasing values**, :meth:`Tools.set_aa_level`. Resolves `#467 <https://github.com/pymupdf/PyMuPDF/issues/467>`_
* **Fixed** issue `#474 <https://github.com/pymupdf/PyMuPDF/issues/474>`_.
* **Fixed** issue `#466 <https://github.com/pymupdf/PyMuPDF/issues/466>`_.
------
**Changes in Version 1.16.13**
* **Added** :meth:`Document.getPageXObjectList` which returns a list of **Form XObjects** of the page.
* **Added** :meth:`Page.setMediaBox` for changing the physical PDF page size.
* **Added** :ref:`Page` methods which have been internal before: :meth:`Page.cleanContents` (= :meth:`Page._cleanContents`), :meth:`Page.getContents` (= :meth:`Page._getContents`), :meth:`Page.getTransformation` (= :meth:`Page._getTransformation`).
------
**Changes in Version 1.16.12**
* **Fixed** issue `#447 <https://github.com/pymupdf/PyMuPDF/issues/447>`_
* **Fixed** issue `#461 <https://github.com/pymupdf/PyMuPDF/issues/461>`_.
* **Fixed** issue `#397 <https://github.com/pymupdf/PyMuPDF/issues/397>`_.
* **Fixed** issue `#463 <https://github.com/pymupdf/PyMuPDF/issues/463>`_.
* **Added** JavaScript support to PDF form fields, thereby fixing `#454 <https://github.com/pymupdf/PyMuPDF/issues/454>`_.
* **Added** a new annotation method :meth:`Annot.delete_responses`, which removes 'Popup' and response annotations referring to the current one. Mainly serves data protection purposes.
* **Added** a new form field method :meth:`Widget.reset`, which resets the field value to its default.
* **Changed** and extended handling of redactions: images and XObjects are removed if *contained* in a redaction rectangle. Any partial only overlaps will just be covered by the redaction background color. Now an *overlay* text can be specified to be inserted in the rectangle area to **take the place the deleted original** text. This resolves `#434 <https://github.com/pymupdf/PyMuPDF/issues/434>`_.
------
**Changes in Version 1.16.11**
* **Added** Support for redaction annotations via method :meth:`Page.add_redact_annot` and :meth:`Page.apply_redactions`.
* **Fixed** issue #426 ("PolygonAnnotation in 1.16.10 version").
* **Fixed** documentation only issues `#443 <https://github.com/pymupdf/PyMuPDF/issues/443>`_ and `#444 <https://github.com/pymupdf/PyMuPDF/issues/444>`_.
------
**Changes in Version 1.16.10**
* **Fixed** issue #421 ("annot.set_rect(rect) has no effect on text Annotation")
* **Fixed** issue #417 ("Strange behavior for page.deleteAnnot on 1.16.9 compare to 1.13.20")
* **Fixed** issue #415 ("Annot.setOpacity throws mupdf warnings")

* **Added** :meth:`Page.annot_names` which returns a list of all annotation names (*/NM* keys).
* **Added** :meth:`Page.load_annot` which loads an annotation given its unique id (*/NM* key).
* **Added** :meth:`Document.reload_page` which provides a new copy of a page after finishing any pending updates to it.
------
**Changes in Version 1.16.9**
* **Fixed** #412 ("Feature Request: Allow controlling whether TOC entries should be collapsed")
* **Fixed** #411 ("Seg Fault with page.firstWidget")
* **Fixed** #407 ("Annot.setOpacity trouble")
* **Changed** methods :meth:`Annot.setBorder`, :meth:`Annot.setColors`, :meth:`Link.setBorder`, and :meth:`Link.setColors` to also accept direct parameters, and not just cumbersome dictionaries.
------
**Changes in Version 1.16.8**
* **Added** several new methods to the :ref:`Document` class, which make dealing with PDF low-level structures easier. I also decided to provide them as "normal" methods (as opposed to private ones starting with an underscore "_"). These are :meth:`Document.xrefObject`, :meth:`Document.xrefStream`, :meth:`Document.xrefStreamRaw`, :meth:`Document.PDFTrailer`, :meth:`Document.PDFCatalog`, :meth:`Document.metadataXML`, :meth:`Document.updateObject`, :meth:`Document.updateStream`.
* **Added** :meth:`Tools.mupdf_disply_errors` which sets the display of mupdf errors on *sys.stderr*.
* **Added** a commandline facility. This a major new feature: you can now invoke several utility functions via *"python -m fitz ..."*. It should obsolete the need for many of the most trivial scripts. Please refer to :ref:`Module`.
------
**Changes in Version 1.16.7**
Minor changes to better synchronize the binary image streams of :ref:`TextPage` image blocks and :meth:`Document.extractImage` images.
* **Fixed** issue #394 ("PyMuPDF Segfaults when using TOOLS.mupdf_warnings()").
* **Changed** redirection of MuPDF error messages: apart from writing them to Python *sys.stderr*, they are now also stored with the MuPDF warnings.
* **Changed** :meth:`Tools.mupdf_warnings` to automatically empty the store (if not deactivated via a parameter).
* **Changed** :meth:`Page.getImageBbox` to return an **infinite rectangle** if the image could not be located on the page -- instead of raising an exception.
------
**Changes in Version 1.16.6**
* **Fixed** issue #390 ("Incomplete deletion of annotations").
* **Changed** :meth:`Page.searchFor` / :meth:`Document.searchPageFor` to also support the *flags* parameter, which controls the data included in a :ref:`TextPage`.
* **Changed** :meth:`Document.getPageImageList`, :meth:`Document.getPageFontList` and their :ref:`Page` counterparts to support a new parameter *full*. If true, the returned items will contain the :data:`xref` of the *Form XObject* where the font or image is referenced.
------
**Changes in Version 1.16.5**
More performance improvements for text extraction.
* **Fixed** second part of issue #381 (see item in v1.16.4).
* **Added** :meth:`Page.getTextPage`, so it is no longer required to create an intermediate display list for text extractions. Page level wrappers for text extraction and text searching are now based on this, which should improve performance by ca. 5%.
------
**Changes in Version 1.16.4**
* **Fixed** issue #381 ("TextPage.extractDICT ... failed ... after upgrading ... to 1.16.3")
* **Added** method :meth:`Document.pages` which delivers a generator iterator over a page range.
* **Added** method :meth:`Page.links` which delivers a generator iterator over the links of a page.
* **Added** method :meth:`Page.annots` which delivers a generator iterator over the annotations of a page.
* **Added** method :meth:`Page.widgets` which delivers a generator iterator over the form fields of a page.
* **Changed** :attr:`Document.is_form_pdf` to now contain the number of widgets, and *False* if not a PDF or this number is zero.
------
**Changes in Version 1.16.3**
Minor changes compared to version 1.16.2. The code of the "dict" and "rawdict" variants of :meth:`Page.getText` has been ported to C which has greatly improved their performance. This improvement is mostly noticeable with text-oriented documents, where they now should execute almost two times faster.
* **Fixed** issue #369 ("mupdf: cmsCreateTransform failed") by removing ICC colorspace support.
* **Changed** :meth:`Page.getText` to accept additional keywords "blocks" and "words". These will deliver the results of :meth:`Page.getTextBlocks` and :meth:`Page.getTextWords`, respectively. So all text extraction methods are now available via a uniform API. Correspondingly, there are now new methods :meth:`TextPage.extractBLOCKS` and :meth:`TextPage.extractWords`.
* **Changed** :meth:`Page.getText` to default bit indicator *TEXT_INHIBIT_SPACES* to **off**. Insertion of additional spaces is **not suppressed** by default.
------
**Changes in Version 1.16.2**
* **Changed** text extraction methods of :ref:`Page` to allow detail control of the amount of extracted data.
* **Added** :meth:`planish_line` which maps a given line (defined as a pair of points) to the x-axis.
* **Fixed** an issue (w/o Github number) which brought down the interpreter when encountering certain non-UTF-8 encodable characters while using :meth:`Page.getText` with te "dict" option.
* **Fixed** issue #362 ("Memory Leak with getText('rawDICT')").
------
**Changes in Version 1.16.1**
* **Added** property :attr:`Quad.is_convex` which checks whether a line is contained in the quad if it connects two points of it.
* **Changed** :meth:`Document.insert_pdf` to now allow dropping or including links and annotations independently during the copy. Fixes issue #352 ("Corrupt PDF data and ..."), which seemed to intermittently occur when using the method for some problematic PDF files.
* **Fixed** a bug which, in matrix division using the syntax *"m1/m2"*, caused matrix *"m1"* to be **replaced** by the result instead of delivering a new matrix.
* **Fixed** issue #354 ("SyntaxWarning with Python 3.8"). We now always use *"=="* for literals (instead of the *"is"* Python keyword).
* **Fixed** issue #353 ("mupdf version check"), to no longer refuse the import when there are only patch level deviations from MuPDF.
------
**Changes in Version 1.16.0**
This major new version of MuPDF comes with several nice new or changed features. Some of them imply programming API changes, however. This is a synopsis of what has changed:
* PDF document encryption and decryption is now **fully supported**. This includes setting **permissions**, **passwords** (user and owner passwords) and the desired encryption method.
* In response to the new encryption features, PyMuPDF returns an integer (ie. a combination of bits) for document permissions, and no longer a dictionary.
* Redirection of MuPDF errors and warnings is now natively supported. PyMuPDF redirects error messages from MuPDF to *sys.stderr* and no longer buffers them. Warnings continue to be buffered and will not be displayed. Functions exist to access and reset the warnings buffer.
* Annotations are now **only supported for PDF**.
* Annotations and widgets (form fields) are now **separate object chains** on a page (although widgets technically still **are** PDF annotations). This means, that you will **never encounter widgets** when using :attr:`Page.firstAnnot` or :meth:`Annot.next`. You must use :attr:`Page.firstWidget` and :meth:`Widget.next` to access form fields.
* As part of MuPDF's changes regarding widgets, only the following four fonts are supported, when **adding** or **changing** form fields: **Courier, Helvetica, Times-Roman** and **ZapfDingBats**.
List of change details:
* **Added** :meth:`Document.can_save_incrementally` which checks conditions that are preventing use of option *incremental=True* of :meth:`Document.save`.
* **Added** :attr:`Page.firstWidget` which points to the first field on a page.
* **Added** :meth:`Page.getImageBbox` which returns the rectangle occupied by an image shown on the page.
* **Added** :meth:`Annot.setName` which lets you change the (icon) name field.
* **Added** outputting the text color in :meth:`Page.getText`: the *"dict"*, *"rawdict"* and *"xml"* options now also show the color in sRGB format.
* **Changed** :attr:`Document.permissions` to now contain an integer of bool indicators -- was a dictionary before.
* **Changed** :meth:`Document.save`, :meth:`Document.write`, which now fully support password-based decryption and encryption of PDF files.
* **Changed the names of all Python constants** related to annotations and widgets. Please make sure to consult the **Constants and Enumerations** chapter if your script is dealing with these two classes. This decision goes back to the dropped support for non-PDF annotations. The **old names** (starting with "ANNOT_*" or "WIDGET_*") will be available as deprecated synonyms.
* **Changed** font support for widgets: only *Cour* (Courier), *Helv* (Helvetica, default), *TiRo* (Times-Roman) and *ZaDb* (ZapfDingBats) are accepted when **adding or changing** form fields. Only the plain versions are possible -- not their italic or bold variations. **Reading** widgets, however will show its original font.
* **Changed** the name of the warnings buffer to :meth:`Tools.mupdf_warnings` and the function to empty this buffer is now called :meth:`Tools.reset_mupdf_warnings`.
* **Changed** :meth:`Page.getPixmap`, :meth:`Document.get_page_pixmap`: a new bool argument *annots* can now be used to **suppress the rendering of annotations** on the page.
* **Changed** :meth:`Page.add_file_annot` and :meth:`Page.add_text_annot` to enable setting an icon.
* **Removed** widget-related methods and attributes from the :ref:`Annot` object.
* **Removed** :ref:`Document` attributes *openErrCode*, *openErrMsg*, and :ref:`Tools` attributes / methods *stderr*, *reset_stderr*, *stdout*, and *reset_stdout*.
* **Removed** **thirdparty zlib** dependency in PyMuPDF: there are now compression functions available in MuPDF. Source installers of PyMuPDF may now omit this extra installation step.
**No version published for MuPDF v1.15.0**
------
**Changes in Version 1.14.20 / 1.14.21**
* **Changed** text marker annotations to support multiple rectangles / quadrilaterals. This fixes issue #341 ("Question : How to addhighlight so that a string spread across more than a line is covered by one highlight?") and similar (#285).
* **Fixed** issue #331 ("Importing PyMuPDF changes warning filtering behaviour globally").
------
**Changes in Version 1.14.19**
* **Fixed** issue #319 ("InsertText function error when use custom font").
* **Added** new method :meth:`Document.get_sigflags` which returns information on whether a PDF is signed. Resolves issue #326 ("How to detect signature in a form pdf?").
------
**Changes in Version 1.14.17**
* **Added** :meth:`Document.fullcopyPage` to make full page copies within a PDF (not just copied references as :meth:`Document.copyPage` does).
* **Changed** :meth:`Page.getPixmap`, :meth:`Document.get_page_pixmap` now use *alpha=False* as default.
* **Changed** text extraction: the span dictionary now (again) contains its rectangle under the *bbox* key.
* **Changed** :meth:`Document.movePage` and :meth:`Document.copyPage` to use direct functions instead of wrapping :meth:`Document.select` -- similar to :meth:`Document.delete_page` in v1.14.16.
------
**Changes in Version 1.14.16**
