v0.3.1

This is a very small update that addresses an issue when serializing standard XRef tables using generate_standard_xref_table. Inputs that would produce tables with multiple subsections would previously fail. This should now be fixed.

v0.3

0.3 includes major changes that should hopefully improve developer experience when reading PDF files.

• pdfnaut now includes typings for many common PDF dictionaries including the trailer, catalog, outlines, and others. (this change introduces a new dependency, typing-extensions, for users of Python 3.11 or earlier)
• PdfDocument has been added as a foundation of the high-level API. It allows quick access to common PDF objects (such as pages)
• pdfnaut now adds a new "strict" mode that warns or fails when parsing non-spec-compliant documents. This also means pdfnaut is also more lenient towards these files (given that strict=False).
• Document lexing should be slightly faster for references since we now first check for a digit before invoking regex.

v0.2

This update adds support for encoding and encrypting objects.

Additions:

• All filters (except Crypt) now support encoding.
• Added a decoder for the RunLengthDecode filter
• The security handler was reworked to allow for encryption of objects.

Removals:

• The TIFF predictor function used previously was implemented improperly. It has now been removed.

Fixes:

• The PNG predictor function previously worked on entire samples rather than on bytes, which led to only one of the color components being preserved. This has now been fixed.

0.1.1

A small update that adds two additions

• Incremental updates are now exposed under a new updates attribute in the PDF parser. See the docs for info.
• An edge case was found when attempting to tokenize an indirect reference at the end of data. This has now been fixed.

v0.1

The first release of pdfnaut. Available on PyPI.
