Hi.
[PATCH 1/2] Improve FT_Outline_Embolden for the unintended arfifacts problem
(#45597):
- The mathematical background is clearly added to the patch.
- Some error situation processing is done naturally during the formula
processing.
- At the bauhaus_256px_win7_ie9.png file, you can see that Microsoft's embolden
did not properly inhibits the unintended artifacts. This patch will handled
properly.
- Because the strength value also affects the unintended artifacts creation, the
strength formula of [PATCH 2/2] should also be used.
[PATCH 2/2] Improve FT_GlyphSlot_Embolden to match more with Microsoft Windows
looks:
- The DirectWrite font rendering appears to have deleted the strange
transformation from the existing GDI. For reference, the GDI matching code has
not been deleted.
- "Advance" values are important to match text layouts.
- The strength value must be an integer pixel value to inhibits blurring the
hinted outline.
More details are commented on the patch.
Thanks.
