)

@Function: cff_get_kerning

@Description: A driver method used to return the kerning vector between two glyphs of the same face.

@Input: face :: A handle to the source face object.

left_glyph :: The index of the left glyph in the kern pair.

right_glyph :: The index of the right glyph in the kern pair.

@Output: kerning :: The kerning vector. This is in font units for scalable formats, and in pixels for fixed-sizes formats.

@Return: FreeType error code. 0 means success.

@Note: Only horizontal layouts (left-to-right & right-to-left) are supported by this function. Other layouts, or more sophisticated kernings, are out of scope of this method (the basic driver interface is meant to be simple).

They can be implemented by format-specific interfaces.

cff_glyph_load ( FT_GlyphSlot  cffslot,
FT_Size  cffsize,

)

@Function: cff_glyph_load

@Description: A driver method used to load a glyph within a given glyph slot.

@Input: slot :: A handle to the target slot object where the glyph will be loaded.

size :: A handle to the source face size at which the glyph must be scaled, loaded, etc.

glyph_index :: The index of the glyph in the font file.

load_flags :: A flag indicating what to load for this glyph. The FT_LOAD_??? constants can be used to control the glyph loading process (e.g., whether the outline should be scaled, whether to load bitmaps or not, whether to hint the outline, etc).

@Return: FreeType error code. 0 means success.
