# fontpic
Goal of the project - allow to easily generate images with text using widely
available CGA/EGA/VGA ROM fonts. This can be useful for generating captcha
images for website or telegram chats.
It comes with 8x8, 8x14 and 8x16 fonts in DOS 866 (Cyrillic) encoding in
[fnt](/fnt) directory. Font files 08x08.fnt, 08x14.fnt, 08x16.fnt were
distributed with the freeware [KeyRus program][1], and are used in this
library by default as a tribute to Dmitry Gurtyak (1971-1998), author of
KeyRus.
Currenly the project supports only raw font files, it's easy to tell if it's
a raw FNT by looking at the file size:
- 8x8 - 2048 bytes
- 8x14 - 3584 bytes
- 8x16 - 4096 bytes
## Where to get more fonts
1. There is a great project that contains a lot of fonts extracted from
different ROMs: [romfont][2]
2. Extract fonts from a BIOS of the old PC. Read the [romfont][2] repository
README.
3. Unpack fonts from the Abandonware programs. I.e. DOS distribution includes
'*.CPI' files that contain fonts. You can use [psf2inc][3] utility to
extract them. If you went down that path, you'd probably know what to do
with the output.
4. Convert BDF fonts.
