Microsoft Windows font files contain the font glyph information the graphics-device interface (GDI) or a graphics driver needs to draw text on a given device. The font-file format supports both raster and vector fonts. Also, Windows extended the font file format for Windows 3.x to increase the maximum size of a font file beyond 64K bytes.
This chapter does not describe the format of Microsoft TrueType font files. For more information about TrueType fonts, see the Microsoft Windows Installation and Update Guide.
