Description Brian Ewins 2006-12-16 05:00:43 UTC

Continuing bug 9350 (rather than post multiple patches on a single bug)

cairo-scaled-font.c rounds glyph positions to the nearest pixel, but this code
path isn't used by the atsui backend, resulting in small differences in the
output from the ft backend.

adds rounding with the same todo comment as in cairo-scaled-font. applied after
the patch in 9350

Comment 2 Brian Ewins 2006-12-16 05:04:08 UTC

Created attachment 8135 [details]
Output of text-rotate after the patch

compare this to the patched output in 9350
