Hello,
Apologies if I am misled here, but I'm noting that
FT_GlyphSlot_Embolden() alter the slot metrics, e.g. code includes.
slot->metrics.width += xstr;
slot->metrics.height += ystr;
Whereas FT_GlyphSlot_Oblique() doesn't. It only calls
FT_Outline_Transform().
Shouldn't FT_GlyphSlot_Oblique alter metrics to expose the typically
altered width?
After I call FT_Render_Glyph() the width found in
face->glyph->bitmap->width is typically larger than the metrics width.
Should not this be reflected in metrics ahead of the render?
(My context is the following: I am trying to understand if it is
possible to obtain the expected size of a bitmap _before_ rendering it.
I need sizes ahead of time to pack rasterized glyphs into an atlas.
Rendering the glyphs twice is out of question because this is an
expensive enough operation it actually does affect my initialization
time meaningfully. Peeking into the slot metrics seems to works well
_unless_ I start using FT_Render_Glyph() in which case there is a
mismatch between the size in metrics and the rendered glyph size).
Being new to FreeType it is possible I am misunderstanding something.
Regards,
Omar
