ReFreezed Bitmap Font converter

This command line program converts a simple custom bitmap font format to AngelCode's BMFont. There is also some basic support for rasterizing TrueType/OpenType fonts.

The ReFreezed Bitmap Font consists of two files: an image with all the glyphs separated by a border, and a text file (descriptor) that specifies what glyphs are in the image (but not any coordinates, unlike BMFont).

Who is this program for?

If you're making bitmap fonts for your game in an image editing program but you don't have a simple way of creating BMFont files, this program could be what you're looking for. There are other programs that focus on rasterizing TrueType fonts into bitmaps - this program however is focusing more on converting a more user-friendly bitmap format to the pretty well-supported BMFont format.

This program was made as a tool for the LÖVE game framework, but if your game engine or framework understands BMFont files (e.g. Unity or MonoGame) then this program may very well be useful for you.
