Description
The .fon format is a Windows font resource file that stores bitmap (raster) fonts or acts as a container referencing font data for use by older Windows applications. It is commonly used for legacy screen fonts, especially fixed-size bitmap fonts used in older Windows GUI elements and MS-DOS era applications. Modern Windows systems retain support for .fon files mainly for backward compatibility with legacy software.
PostScript Type 3 consists of glyphs defined using the full PostScript language, rather than just a subset. Because of this, a Type 3 font can do some things that Type 1 fonts cannot do, such as specify shading, color, and fill patterns.
