Summary [META] Add CSS blending to WebKit

Rik Cabanier

Reported 2012-07-20 15:44:22 PDT

I would like to add CSS blending to WebKit. We have a draft specification that we will push to WD soon. The first implementation will be done using the 'webkit-' prefix and implement a subset of the whole feature (only the blending of whole elements).

(In reply to comment #1) > How will this work with compositing? I was planning on adding compositing at a later stage. For now, blending will always be done with 'src-over'.

Comment on attachment 154983 [details] patch for parsing. code is disabled for now You should add CSS_COMPOSITING to all the build system first. See http://trac.webkit.org/changeset/123350 for an example.
