Description Regina Henschel 2011-01-05 21:20:40 UTC
Start Impress and load the attached palette and then the file.
The palette contains some axial gradients, so that you can watch the display of
some borders.
The file contains a sreenshot of the rectangles in edit mode.
Go to presentation mode and compare the displayed rectangles with the
screenshot. Notice, that the axial gradients have wrong borders. It seems as if
the border is not added symmetrically as it should be for an axial gradient.

DEV300m76 is OK. I see the bug first in DEV300m77 and unfortunately in OOo33RC8 too.

I can confirm this bug. Happens in LibreOffice 3.3 RC2, too.
Comment 4 wolframgarten 2011-01-06 10:04:21 UTC
Reproducible in DEV300_m96 and OOO330_m18. Reassigned.

This issue has been introduced by issue 105937 in cws thbfixes10 (which was
integrated into DEV300 m77): a simple mix-up of method names.  In
cppcanvas/source/mtfrenderer/implrenderer.cxx the method
ImplRenderer::createGradientAction called
basegfx::tools::createLinearODFGradientInfo instead of
basegfx::tools::createAxialODFGradientInfo to paint axial gradients.

The border value had to be adapted for the new method: the area covered by the
actual gradient (1 minus the border) was doubled to counteract the compression
caused by painting (in effect) two linear gradients side-by-side.
