A PDF file that just draws a small rectangular area showing that the lines
all radiate in 8 directions from a single point in the shading.
This is a ShadingType 4: 'Free form Gouraud-shaded triangle mesh'
Back to Ray from IRC discussion:
<Robin_Watts> The problem is that we're getting stitch lines where the edges
of the shading meet, and to fix that we need to push a
transparency group before starting the mesh rendering. [10:12]
<Robin_Watts> and ray_laptop said he'd do it because he had experience in that
area.
Oops. I committed the fix (rev 12302) and forgot to close this bug. |
