- Fixed a typo in code for reading a "\b" escape character in strings.
- Improved __repr__ in FloatObject.
- Fixed a bug in reading octal escape sequences in strings.
- Added getWidth and getHeight methods to the RectangleObject class.
- Fixed compatibility warnings with Python 2.4 and 2.5.
- Added addBlankPage and insertBlankPage methods on PdfFileWriter class.
- Fixed a bug with circular references in page's object trees (typically
annotations) that prevented correctly writing out a copy of those pages.
- New merge page functions allow application of a transformation matrix.
- To all patch contributors: I did a poor job of keeping this ChangeLog
up-to-date for this release, so I am missing attributions here for any
changes you submitted. Sorry! I'll do better in the future.
Version 1.12, 2008-09-02
------------------------
- Added support for XMP metadata.
- Fix reading files with xref streams with multiple /Index values.
- Fix extracting content streams that use graphics operators longer than 2
characters. Affects merging PDF files.
Version 1.11, 2008-05-09
------------------------
- Patch from Hartmut Goebel to permit RectangleObjects to accept NumberObject
or FloatObject values.
- PDF compatibility fixes.
- Fix to read object xref stream in correct order.
- Fix for comments inside content streams.
Version 1.10, 2007-10-04
------------------------
- Text strings from PDF files are returned as Unicode string objects when
pyPdf determines that they can be decoded (as UTF-16 strings, or as
PDFDocEncoding strings). Unicode objects are also written out when
necessary. This means that string objects in pyPdf can be either
generic.ByteStringObject instances, or generic.TextStringObject instances.
- The extractText method now returns a unicode string object.
- All document information properties now return unicode string objects. In
the event that a document provides docinfo properties that are not decoded by
pyPdf, the raw byte strings can be accessed with an "_raw" property (ie.
title_raw rather than title)
- generic.DictionaryObject instances have been enhanced to be easier to use.
Values coming out of dictionary objects will automatically be de-referenced
(.getObject will be called on them), unless accessed by the new "raw_get"
method. DictionaryObjects can now only contain PdfObject instances (as keys
and values), making it easier to debug where non-PdfObject values (which
cannot be written out) are entering dictionaries.
- Support for reading named destinations and outlines in PDF files. Original
patch by Ashish Kulkarni.
- Stream compatibility reading enhancements for malformed PDF files.
- Cross reference table reading enhancements for malformed PDF files.
- Encryption documentation.
- Replace some "assert" statements with error raising.
- Minor optimizations to FlateDecode algorithm increase speed when using PNG
predictors.
Version 1.9, 2006-12-15
-----------------------
- Fix several serious bugs introduced in version 1.8, caused by a failure to
run through our PDF test suite before releasing that version.
- Fix bug in NullObject reading and writing.
Version 1.8, 2006-12-14
-----------------------
- Add support for decryption with the standard PDF security handler. This
allows for decrypting PDF files given the proper user or owner password.
- Add support for encryption with the standard PDF security handler.
- Add new pythondoc documentation.
- Fix bug in ASCII85 decode that occurs when whitespace exists inside the
two terminating characters of the stream.
Version 1.7, 2006-12-10
-----------------------
- Fix a bug when using a single page object in two PdfFileWriter objects.
- Adjust PyPDF to be tolerant of whitespace characters that don't belong
during a stream object.
- Add documentInfo property to PdfFileReader.
- Add numPages property to PdfFileReader.
