The function stbtt_BakeFontBitmap is used to write bitmap data into set->image->pixels (where set is a GlyphSet).
|
||
|
|
Note that set->image->pixels need data in RGB format. After stbtt_BakeFontBitmap call the bitmap data are converted into RGB.
|
||
|
|
With a single call many glyphs corresponding to a range of codepoints, all in a
|
||
|
|
single image.
