What is a .bdf file?
application/x-font-bdf
BDF (Glyph Bitmap Distribution Format) is a plain-text format for bitmap fonts from the X11 world. Each glyph is described by a small grid of pixels given as hex rows, along with metrics and encoding. It is human-readable and was the standard way to ship fixed-size screen fonts before scalable outlines.
How to use a .bdf file
Use an example BDF file to test bitmap-font parsers and converters (for example BDF to PCF, TTF, or a sprite sheet), and retro or embedded rendering pipelines.
