[cl-pdf-devel] PATCH: PDF transparency support

[Eric Marsden]

Hi,

The attached patch adds support for PDF transparency, using the existing
gstate mechanism. It allows you to specify transparency for stroke and
fill operations seperately. The "blend mode" can also be specified. The
patch includes an example.

Note that viewer support for different blend modes is variable (works OK
in Adobe Reader, Foxit Reader, xpdf but not in evince/poppler).
