Introduction to fontdir

The content of a typical fontdir file is as follows:

Fixed fixed_120_50.qpf qpf N 50 120

Helvetica helvetica_80_50.qpf qpf N 50 80

Helvetica helvetica_120_50.qpf qpf N 120 U

Helvetica helvetica_120_75.qpf qpf N 120 U

Helvetica helvetica_140_75.qpf qpf N 75 140

Helvetica helvetica_180_75.qpf qpf N 75 180

Each line in the file identifies a specific font. The meaning of each segment is: the first column is name, the second column is file, and the third column is Renderer, which is equivalent to the font format. Therefore, BDF, TTT, qpf and other options. Column N indicates iitalic and whether it is italic. The fifth column indicates weight, where 50 indicates normal and 75 indicates bold. The sixth column indicates the size, for example, 120 indicates 12pt. The seventh column is flags. There are three options: S = smooth (Anti-aliased) U = Unicode range when saving (default is Latin 1 A = ASCII range when saving (default is Latin 1 ))
