Hi all, For the moment, it seems that drawing on canvas is done without accounting for gamma, actually making wrong assumptions, like a^x + b^x = (a + b)^x. This gives incorrect results, although they are not always obvious to perceive. For example, all shapes and font antialiasing is incorrect, as are gradients. I propose to address this issue by ensuring that all drawing operations are done in linear space.
I wrote a thorough explanation in a W3C bug report, so please see http://www.w3.org/Bugs/Public/show_bug.cgi?id=12444 for more information. As a picture is often more expressive than text, please take a look at the example picture: http://www.w3.org/Bugs/Public/attachment.cgi?id=975 (has to be displayed unscaled). I don’t know whether this is the appropriate mailing list to present this problem. The actual drawing is probably done through platform-specific libraries, so maybe this issue concerns those? If it is the case, could someone give me a list of these platform-specific libraries? Kind regards, Hugues De Keyzer La sola konstanto en la vivo estas la ŝanĝo.
