New issue 24191 by [email protected]: Support transparency in text drawing http://code.google.com/p/chromium/issues/detail?id=24191 ( migrated from http://buganizer/issue?id=700464 ) arv on May 04 2007 11:30 (New) Summary rgba does not work for CSS color property Component Chrome > Deprecated > WebKit > Layout Reporter arv CC chrome-team Type Bug Priority P2 Severity S2 In prod false Notes Given the following CSS rule: seletor { color: rgba(0, 0, 255, 0.5); } the text should be blue and 50% transparent. However the text is fully opaque. temp.html darin on July 11 2007 16:01 (New) Notes I believe this is particular to our text drawing code. The same style rule works properly when applied to the background color of a DIV. mal on July 11 2007 20:06 (New) Hotlist Cr__Rel_1.0 brettw on July 13 2007 11:15 (New) Summary Support transparency in text drawing Notes Unfortunately, I don't thing GDI supports drawing non-opaque text. Does anybody know a way? We can hack this by making a copy of the background where the text is (so ClearType does the right thing), drawing the text opaque, and combining that layer with the background with the correct transparency. darin on July 13 2007 13:06 (New) Notes We should look at how Firefox implements this on Windows. mal on March 22 2008 14:40 (New) CC chrome-bugs eseidel on May 01 2008 12:44 (New) Hotlist Cr__Rel_Future, Cr__Untriaged Notes This is a real bug. Not sure it's critical for Beta. But it would be nice to have. upstream webkit will also have to fix this for their GDI text path. I agree, this would be nice to fix, but punting out of Beta for now. We can pull it back if someone actually finds a website which depends on having transparent text. eseidel on May 01 2008 16:36 (New) Notes mitzpettel (Dan Bernstein, apple employee) has added support for transparent GDI text in upstream WebKit. We'll definitely want to unify our text drawing code with Safari post-beta. brettw on May 01 2008 17:57 (New) Notes Also note that mitzpettel (Dan Bernstein, apple employee)'s transparent GDI text drawing code in WebKit is wrong. We should write a correct one and give it to them rather than copying theirs. mal on July 17 2008 11:17 -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
