Revision history for Perl module CAM::PDF

1.54  26 Mar 2011
      [FIXES]

        Thanks to Charlie Katz for a sample PDF

1.53  25 Mar 2011

        http://www.cpanforum.com/posts/11494

1.52  02 Oct 2008
      [FIXES]
      - Better handling of failures during filter loading
        (rlane10 via http://www.nntp.perl.org/group/perl.cpan.testers/2008/10/msg2361238.html)

1.51  28 Sep 2008
      [FIXES]
      - Support PDFs with 24-bit offsets in the xref stream (PDF v1.5 only)
        (thanks to Dan Richman for reporting the problem and providing an example)

1.50  20 Sep 2008
      [ENHANCEMENTS]
      - Support for reading PDF 1.5 compressed object streams and cross reference streams.
        (we cannot write this style, but we can append to it)
      [FIXES]
      - Decompression of PNG-filtered streams was totally broken.
      - Deleting pages now also deletes back references from annotations on that page.
      - cleanse() now removes PieceInfo data.  I have no idea what
        PieceInfo does, but it had a whole bunch of page back links
        that broke page deletion.

1.21  13 Aug 2008
      [FIXES]
      - Permit comments after the %%EOF, like Adobe Reader does.  Thanks to
        Malcolm Cook for pointing out the incompatibility.

        are different

        RT #35555 (credit Eric Hall and his anonymous employee).

        Andrew Cadman for finding the bug and suggesting a fix

1.12  27 Nov 2007
      [FIXES]
      - I just realized that CAM::PDF::Renderer::Text was useless
        because it just printed to STDOUT.  Fixed to offer a
        toString() method instead.  Fuse::PDF wants this feature.
      - Fixed a typo in the Synopsis of CAM::PDF::Content

1.11  20 Nov 2007
