Hardware font

A hardware font, or VGA ROM font, contains a set of 256 monochrome and monospaced characters, the character width is always eight pixels. Each pixel is described as a single bit, on or off, and so each line is described as a single byte; therefore the byte size corresponds to the total number of lines. A single character's eight is 1/256 that amount. A character's description is the character height bytes found at the character number × character height offset in the file. There is no header or other form of meta-information.

This format is the one used by system consoles, terminal emulators and similar command line interfaces.

ZDoom uses it only for ANSI screen emulation and uses the one described in the file vga-rom-font.16 contained in zdoom.pk3. This font format cannot be used for in-game fonts.
