  • v1.12 Changes

    September 02, 2008
    • 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.

  • v1.11 Changes

    May 09, 2008
    • 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.

  • v1.10 Changes

    October 04, 2007
    • 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.

  • v1.9 Changes

    December 15, 2006
    • 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.

  • v1.8 Changes

    December 14, 2006
    • 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.

  • v1.7 Changes

    December 10, 2006
    • 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.

  • v1.6 Changes

    June 06, 2006
    • 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.

  • v1.5 Changes

    January 28, 2006
    • ๐Ÿ›  Fix a bug where merging pages did not work in "no-rename" cases when the second page has an array of content streams.

    • โœ‚ Remove some debugging output that should not have been present.

  • v1.4 Changes

    January 27, 2006
    • โž• 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.

    • โž• 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.

    • ๐Ÿ”จ 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.

    • โž• Add new decoding functions for standard PDF filters ASCIIHexDecode and ASCII85Decode.

    • ๐Ÿ”„ Change url and download_url to refer to new pybrary.net web site.

  • v1.3 Changes

    January 23, 2006
    • ๐Ÿ›  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.

    • ๐Ÿ›  Fix a bug where inheriting attributes from page nodes did not work.
