[webkit-dev] Support for CSS3 gradients landed; ports will need minor changes

2011-01-03 Thread Simon Fraser 
I just landed support for CSS3 gradients (see 
http://dev.w3.org/csswg/css3-images/#gradients), via 
https://bugs.webkit.org/show_bug.cgi?id=28152.

The spec now allows elliptical gradients. Since some platforms may be able to 
render elliptical gradients natively, the code relies on the platform to render 
such gradients. In CG, this is done via a scale transform on the graphics 
context.

Non-CG platforms will need to make changes to do something similar so what I do 
for CG:

CGContextTranslateCTM(ctx, m_p0.x(), m_p0.y());
CGContextScaleCTM(ctx, 1, 1 / aspectRatio());
CGContextTranslateCTM(ctx, -m_p0.x(), -m_p0.y());

Please file a bug and fix your port accordingly.

Thanks
Simon

I've filed https://bugs.webkit.org/show_bug.cgi?id=51841 about making
the change for Chromium/Skia.
