FT_GLYPH_FORMATS

An enumeration type used to describe the format of a given glyph image. Note that this version of FreeType only supports two image formats, even though future font drivers will be able to register their own format.

FT_GLYPH_FORMAT_NONE

The value 0 is reserved.

FT_GLYPH_FORMAT_COMPOSITE

The glyph image is a composite of several other images. This format is only used with FT_LOAD_NO_RECURSE, and is used to report compound glyphs (like accented characters).

FT_GLYPH_FORMAT_BITMAP

The glyph image is a bitmap, and can be described as an FT_Bitmap. You generally need to access the ‘bitmap’ field of the FT_GlyphSlotRec structure to read it.

FT_GLYPH_FORMAT_OUTLINE

The glyph image is a vectorial outline made of line segments and Bezier arcs; it can be described as an FT_Outline; you generally want to access the ‘outline’ field of the FT_GlyphSlotRec structure to read it.

FT_GLYPH_FORMAT_PLOTTER

The glyph image is a vectorial path with no inside and outside contours. Some Type 1 fonts, like those in the Hershey family, contain glyphs in this format. These are described as FT_Outline, but FreeType isn’t currently capable of rendering them correctly.
