Description Jonathan Watt 2006-03-18 09:57:52 UTC

See https://bugzilla.mozilla.org/show_bug.cgi?id=330682

When cairo_pattern_create_radial(cx0, cy0, 0.0, cx1, cy1, radius1) is called and
[cx0,cy0] is on or outside the circumference defined by cx1, cx2 and radius1
then we get rendering anomalies. See the testcases attached to the Mozilla bug
above:

Perhaps cairo is the place this should be caught?

CC'ing keithp since cworth tells me he's done some radial gradient stuff recently.

Comment 2 Søren Sandmann Pedersen 2010-10-13 06:17:13 UTC

The radial gradients have changed enough that this bug probably isn't relevant anymore.
