Description zeniko 2009-08-04 10:57:15 UTC 
The main blend modes used (besides Normal) seem to be Multiply and Overlay.

Please clarify this bug with more information or we will close it.
Comment 2 zeniko 2009-08-06 10:28:35 UTC 
Fitz currently doesn't support any blend modes beside Normal which causes many PDF 
documents to misrender, e.g. http://sumatrapdf.googlecode.com/issues/attachment?
aid=7759301644859318168&name=911.pdf (see the URL and the issues which have been 
merged into it for further such documents).

This bug is about changing adding support for them (and for SumatraPDF we seem to 
require mainly the Multiply and Overlay modes).

Blend modes have been implemented. There remains a known issue where objects drawn after a clip mask is installed to be blended against a transparent backdrop instead of the earlier objects.

Zeniko: Is this bug still relavent? The link to the document doesn't work. Can you update it with a working one please?

Thanks.

As I've originally filed it, this bug has been fixed for over a year (see comment #4).

Closing. Thanks.
