Description zeniko 2010-10-16 18:31:03 UTC
Created attachment 6804 [details]
document with misrendered title background

On pages 2 and 3 of the attached document, the title should have a solid yellow background (it at least does in Adobe Reader).

Turns out that this is just due to dozens of very thin fills all being smudged out - because they don't quite touch - instead of forming the (apparently) expected whole:

1 1 0.604 scn % the expected yellow
63.48 738.92 216 -0.06 re f
63.48 738.68 216 -0.06 re f
63.48 738.44 216 -0.06 re f
% etc.

It's files like this that make me wonder if we should even bother to antialias vector graphics at all. It may be worth considering grid-fitting rectilinear paths, like we have started doing for images.
