849576 - SVG / radialGradient - focal point of radial gradient not rendered correctly

Status: RESOLVED DUPLICATE of bug 828157

(Core :: SVG, defect)

Description

[Patrick Storz]

Attachment: testcase (sample SVG showing the problem)

The attributes "fx" and "fy" of the SVG 1.1 element "radialGradient" (defining the focal point of the radial gradient) aren't rendered correctly. The center of the gradient is moved instead of shifting the focal point.

Attachments:
- testcase: sample SVG showing the problem
- wrong rendering of the testcase in Firefox 19.0.2
- correct rendering of the testcase by Inkscape

See URL for details in SVG 1.1 specification.

I get the correct rendering in Firefox 20b4. So maybe the problem has already been fixed?

Sounds like bug 828157? Does turning hardware acceleration off fix it? If so it's a duplicate of that bug. Maybe mjh563 does not have a graphics card that Firefox will use for HWA.

Yes, that's totally bug 828157. The testcase provided there does basically the same as mine here. However this has nothing to do with stop-colors as it says in the title, therefore I didn't consider the bug to be relevant to my problem in the first place.

Disabling HW acceleration fixes the problem also for me as described in the other bug.

In that case, let's use your title :-)
