One small thing though - when you use the LCD/BGR style fonts,
you get a mismatch between the font metrics and bitmap size.
So if you're using FT_LOAD_TARGET_LCD, then some of these may
glyph.bitmap_left != (glyph.metrics.horiBearingX >> 6);
glyph.bitmap_top != (glyph.metrics.horiBearingY >> 6);
glyph.bitmap.width != (glyph.metrics.width >> 6);
glyph.bitmap.rows != (glyph.metrics.height >> 6);
The result could be a crash, clipping, or misalignment of
glyphs, depending on the assumptions made by your blitting code.
I asked about this on the FT mailing list, and unfortunately,
they don't believe that the 1 or 2 pixels of padding added to
the bitmap to accommodate the LCD rendering belongs in metrics.
The fix is simply using bitmap_left, bitmap_top, bitmap.width,
bitmap.height, instead of the metrics.
I was looking at the commits and saw that you added kerning, so
was wondering if you hit this problem.
Thank you for advice.
It looks like I faced this problem when one of fonts was selected
As well, I see wrong monotype fonts character placement not
