Bug Fixes (BUG):
- XmpInformation._converter_date was unusable (#921)
- PEP8 renaming (#905)
- XmpInformation missing method _getText (#917)

This release adds a lot of deprecation warnings in preparation of the PyPDF2 2.0.0 release. The changes are mostly using snake_case function-, method-, and variable-names as well as using properties instead of getter-methods.

PyPDF2.utilsmodule private - Rename of core classes:

Note: This ChangeLog has not been kept up-to-date for a while. Hopefully we can keep better track of it from now on. Some of the changes listed here come from previous versions 1.14 and 1.15; they were only vaguely defined. With the new _version.py file we should have more structured and better documented versioning from now on.
-
Defined
PyPDF2.__version__ -
Fixed encrypt() method (from Martijn The)
-
Improved error handling on PDFs with truncated streams (from cecilkorik)
-
Python 3 support (from kushal-kumaran)
-
Fixed example code in README (from Jeremy Bethmont)
-
Fixed an bug caused by DecimalError Exception (from Adam Morris)
-
Many other bug fixes and features by:
jeansch Anton Vlasenko Joseph Walton Jan Oliver Oelerich Fabian Henze And any others I missed. Thanks for contributing!
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
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.
-
Add pages property to PdfFileReader.
-
Add extractText function to PdfFileReader.
-
Add basic support for comments in PDF files. This allows us to read some ReportLab PDFs that could not be read before.
-
Add "auto-repair" for finding xref table at slightly bad locations.
-
New StreamObject backend, cleaner and more powerful. Allows the use of stream filters more easily, including compressed streams.
-
Add a graphics state push/pop around page merges. Improves quality of page merges when one page's content stream leaves the graphics in an abnormal state.
-
Add PageObject.compressContentStreams function, which filters all content streams and compresses them. This will reduce the size of PDF pages, especially after they could have been decompressed in a mergePage operation.
-
Support inline images in PDF content streams.
-
Add support for using .NET framework compression when zlib is not available. This does not make pyPdf compatible with IronPython, but it is a first step.
-
Add support for reading the document information dictionary, and extracting title, author, subject, producer and creator tags.
-
Add patch to support NullObject and multiple xref streams, from Bradley Lawrence.
-
Fix a bug where merging pages did not work in "no-rename" cases when the second page has an array of content streams.
-
Remove some debugging output that should not have been present.
-
Add capability to merge pages from multiple PDF files into a single page using the PageObject.mergePage function. See example code (README or web site) for more information.
-
Add ability to modify a page's MediaBox, CropBox, BleedBox, TrimBox, and ArtBox properties through PageObject. See example code (README or web site) for more information.
-
Refactor pdf.py into multiple files: generic.py (contains objects like NameObject, DictionaryObject), filters.py (contains filter code), utils.py (various). This does not affect importing PdfFileReader or PdfFileWriter.
-
Add new decoding functions for standard PDF filters ASCIIHexDecode and ASCII85Decode.
-
Change url and download_url to refer to new pybrary.net web site.
-
Fix new bug introduced in 1.2 where PDF files with \r line endings did not work properly anymore. A new test suite developed with various PDF files should prevent regression bugs from now on.
-
Fix a bug where inheriting attributes from page nodes did not work.
-
Improved support for files with CRLF-based line endings, fixing a common reported problem stating "assertion error: assert line == "%%EOF"".
-
Software author/maintainer is now officially a proud married person, which is sure to result in better software... somehow.
-
Add capability to rotate pages.
-
Improved PDF reading support to properly manage inherited attributes from /Type=/Pages nodes. This means that page groups that are rotated or have different media boxes or whatever will now work properly.
-
Added PDF 1.5 support. Namely cross-reference streams and object streams. This release can mangle Adobe's PDFReference16.pdf successfully.
-
