Posted from: 82.170.157.116 43615 1 ian 2010-12-29 08:28:21 +0000 Do you have a test case demonstrating this? 44537 2 ian 2011-01-21 02:11:21 +0000 Philip`: Can you comment on this? 44538 3 excors 2011-01-21 02:31:25 +0000 Most browsers use premultiplied alpha so transparent white and transparent black both get encoded as (0,0,0,0) which gets decoded into rgba(0,0,0,0) - they can never distinctly represent transparent white. It shouldn't affect correctly-implemented antialiasing either way, anyway. I guess it's most likely that the original reporter was confused. 45361 4 ian 2011-02-11 01:31:27 +0000 EDITOR'S RESPONSE: This is an Editor's Response to your comment.
