Revision history for Perl module CAM::PDF
1.58 28 May 2012
Many thanks for Vadim Repin for numerous excellent bug reports!
[FIXES]
- Appended pdf revisions incorrectly incremented object generation numbers
https://rt.cpan.org/Ticket/Display.html?id=76513
- Appending pdf revisions was broken for non-linearized PDFs
https://rt.cpan.org/Ticket/Display.html?id=76514
- Allow multiple "startxref" statements in the last 1024 bytes -- unlikely, but possible
https://rt.cpan.org/Ticket/Display.html?id=77508
- Allow whitespace at the beginning of an indirect object (I think the PDF spec is
ambiguous about this)
https://rt.cpan.org/Ticket/Display.html?id=76512
- Allow backspace character
https://rt.cpan.org/Ticket/Display.html?id=76151
[DOCUMENTATION]
- mention $pdf->setPageContent($pagenum, $tree->toString());

1.57 17 Dec 2011
[FIXES]
- Test for undef streams instead of truth, to allow streams like '' or '0'
Thanks to Thorsten Schwander for the patch
- Failed to parse PDF 1.5 cross reference streams where a
1024-byte boundary happened to fall between "endstream" and
"endobj" do to a logic error.
Thanks to Thorsten Schwander for the report and fix suggestion
1.56 13 Dec 2011
[FIXES]
- Workaround for corrupt PDFs that have 'n' records in their index that point to byte zero
of the file. Silently treat those as 'f' records. Yet another case of Acrobat supporting
broken PDFs, so the rest of us have to support them too...
Thanks to Mark Hunnibell for a sample PDF that demonstrated the problem
1.55 22 Jun 2011
[FIXES]
- Performance enhancement saving large files
https://rt.cpan.org/Ticket/Display.html?id=69021
Thanks to David Porter of Audacitas Limited for the patch
1.54 26 Mar 2011
[FIXES]
- appendPDF was broken intermittently if appended doc was bigger than main doc
Thanks to Charlie Katz for a sample PDF
http://chrisdolan.net/talk/2011/03/26/cam-pdf-fixes-appendpdf-bug/
1.53 25 Mar 2011
[FIXES]
- Handle PDF 1.5 case where "endstream" token crosses a 1024-byte boundary
Thanks to Charlie Katz for a sample PDF
- Allow whitespace after the 'stream' token for better interoperability

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.
1.20 26 Jun 2008
[ENHANCEMENTS]

- Support for reading PDFs where the owner and user passwords
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]

because it just printed to STDOUT. Fixed to offer a
toString() method instead. Fuse::PDF wants this feature.

- disable the "node has only one kid and no parent" error
This is a case where the delete code does a poor job of
maintaining a balanced page tree and then complains about it's
own bad work. This should eventually be fixed, but for now,
removing the die() is good enough.
