TrueType Font Driver Functions

TrueType font drivers must support the functions listed in the following table.

Function	Description
DrvGetTrueTypeFile	Gives GDI efficient access to the memory-mapped TrueType font file.
DrvQueryTrueTypeOutline	Returns glyph handles in native TrueType format.
DrvQueryTrueTypeTable	Gives GDI access to specific files in the TrueType font file format.

All these functions provide GDI with information about TrueType font files. DrvQueryTrueTypeTable should give GDI access to specific tables in the TrueType font-file format. DrvQueryTrueTypeOutline must send GDI glyph outlines in native TrueType format. DrvGetTrueTypeFile returns to GDI the TrueType driver's private entry point that allows GDI efficient access to the memory mapped TrueType font file.
