Excellent, thank you! I used this as inspiration to write a new test case for cairo's test suite, (ft-show-glyphs-table). And it nicely demonstrates Adrian's bug fix for cairo-pdf. Meanwhile, though, the test totally fails with cairo-ps, (all the glyphs end up on top of each other). In general, we'd hope that a bug fix in the cairo-pdf-operators.c, (which is the file used by both cairo-pdf and cairo-ps in spite of "pdf" in the name), would fix both backends. But clearly there's something else broken here. Adrian, ready to work your magic again? I'll look and see if I can't figure out something myself in the meantime. (I want whack-a-mole to end now and let's get cairo 1.6 out the door.) > Another version of this program gives assertion failure with > FreeSansItalic.ttf: http://article.gmane.org/gmane.comp.lib.cairo/9166 > (file test.c, cairo 1.4.14 on amd64, but not 1.5.x). Thanks for the report. So somebody might want to backport something like Chris' recent fixes to 1.4, but it still likes like the assertion failures have their original cause in a buggy font. Anyone interested in looking closer at that? -Carl
