FONT (NFNT)
Synopsis
FONT ID <FontResourceId.n> FONTID <FontId.n> <FontFileName.s>FONT file format
The file containing the font information is plain ASCII. To understand how it works it is first necessary to understand how a font is arranged in memory. A font consists of four main parts: a header, a bitmap image, a bitmap location table, and an offset/width table. The bitmap image and location table are generated for you automatically.
The ASCII file consists of two parts: the header and the font data (glyph objects). A full font file is provided with the PilRC distribution.
The FONT header has the following fields:
- fontType
The purpose of this field is unknown. The ROM fonts define this value to be 36864.
- maxWidth
Defined as “maximum character width.” If not set, it is automatically set to the width of the widest character.
- kernMax
Defined as “negative of maximum kern value.” The purpose of this field is unknown.
- nDescent
Defined as “negative of descent.” The purpose of this field is unknown, and is not used in the ROM fonts.
- fRectWidth
Defined as “width of font rectangle.” If not set, it is automatically set to the width of the widest character.
- fRectHeight
Defined as “height of font rectangle.” If not set, it is automatically set when the first glyph is defined.
All characters must be exactly this height.
- ascent
The number of rows that make up the ascending part of the glyphs. Ascent plus descent equals
fRectHeight. This value should be set.- descent
The number of rows that make ...
