Bitmap Font Generator
This program will allow you to generate bitmap fonts from TrueType fonts. The application generates both image files and character descriptions that can be read by a game for easy rendering of fonts.
download installer for v1.9c (219KB)
If you don't have an image viewer capable of reading TGA, PNG, or DDS files, I recommend PUPP, another free product from AngelCode.
Features
- Both 16bit unicode and 8bit character sets are supported
- Optimal use of texture space, i.e. as little unused area as possible
- Support for kerning pairs
- Easy to use file format, either normal text file or xml files. Binary format is available for those that prefer that
- 8bit or 32bit texture output (TGA, PNG, and DDS files)
- Option for packing 4 layers of font images into 1 32bit texture. Needs special shader to render with, but saves a lot of memory
- Anti-aliasing, both through Windows native font smoothing and super sampling
- Configurable padding and spacing between characters
- Select characters from text file
- Generate bitmap font from command line
- Import colored images as characters, supports: bmp, jpg, tga, dds, png
- Optional outline to font characters
- Optional packing of characters with outline into 1 channel. Needs special shader to unpack during rendering, but saves a lot of memory.

Work in Progress
Some of the things that will be implemented in future versions:
- Improve packing routine to leave even less unused space of the textures.
- Allow output with fixed height, for easier post edit in graphics programs.
- Allow use of character encoding for the text file which characters are selected from. Should support at least 8bit OEM, UTF-8, and UTF-16.
- Improved font generation
- Add support for ClearType as anti-aliasing method again.
- Support for drop shadow.
- Support for blurring.
- Improve the useability.
- Add a 'clear all' option that will clear all characters in all subsets.
- Selecting characters from a file could support a drag-and-drop interface.
- Importing images over characters could also support a drag-and-drop interface.
- Add logfile output for missing glyphs when scanning text files for used characters.
- Add mouse over information for characters, i.e. character code, etc.
- Complete unicode support with support for the characters above 65535.
- Add font preview
- Allow user to write text and see the outcome. It should be possible to encode special characters as icons are usually imported over non-visible glyphs
- Improve icon import
- Skip kerning information for imported icons that are overriding font characters.
- Allow offsets and abc widths of imported icons to be adjusted manually.
- Store relative path in the configuration file, so that the project can be moved without having to import all images again.
- Allow importing grayscale images into a single channel, rather than full 32bit.
- Warn if imported icon is larger than output texture.
- Add plugin support for output formats.
- Allow the plugins to format both font descriptor and image files.
