Upstream changes:
2.020 2013-01-20
- Give a more informative error message when a PDF file using a
cross-reference stream is encountered. The Known Issues section
of the documentation includes pointers on how to add support in
case someone else can get to this before I do.
- Text using TrueType fonts is now searchable again. In version
0.61, an undocumented -unicodemap option was added to nearly all
of the font resource methods, which only included a ToUnicode
CMap if it was set (and it's required in order for PDF readers
to be able to identify individual characters if BaseEncoding
isn't present, which it isn't for TrueType fonts).
I've left the -unicodemap option in place, and it's still
undocumented (except here), but it's now on by default. Call
$pdf->ttfont($fontfile, -unicodemap => 0) if you want to disable
it for performance or file size reasons.
- Add a note to the stringify method's documentation saying that
it's a destructive operation.
- The various filter types have their own classes in the
PDF::API2::Basic::PDF::Filter namespace now, rather than having
all of the packages in Filter.pm.
- To facilitate testing and ensure that identically-generated PDFs
have identical output in Perl 5.17.5 or later, PDF dictionary
keys are now sorted during output.
