A font resource consists of two parts: a directory and its components. The font-directory data describes all the fonts in a resource. This data includes a value specifying the number of fonts in the resource and a table of metrics for each of these fonts. The font-component data describes a single font in the resource. There is one component for each of the fonts in the resource. The component data is identical to the data found in a Windows font file (.FNT).
Each entry in the executable file's resource table contains a member that identifies the resource type. The RT_FONTDIR and RT_FONT constants identify a font directory and a font component, respectively.
