- Bitmap Font Generator - Documentation. Back to main page. You can open the export options dialog by going to the Options menu and choosing Export options, or you can just press T on the keyboard. This dialog controls how the font will be stored, i.e. Texture layout, file format, etc.
- From the free options, AngelCode produces the better output, but it is only available in Windows. When you use it, export the font data in XML format, and the texture as a PNG-file with white characters on a transparent background (32 bit).
- 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. The program is freeware and open source, but a donation is greatly appreciated.
A bitmap font is an image/texture file (just like a sprite sheet), and a text file with the glyphs coordinates. For each glyph, you will find its size and position on the texture file, and different parameters for the text positions when you write a sentence (the kernings for example). I have a question concerning Bitmap fonts. I need to create fonts for screen device. Clipart for mac mini. It should consists of bitmaps of all printable characters. To get a bitmaps of all characters I am using the fol.
The program is freeware and open source, but a donation is greatly appreciated.
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
- Support for complete Unicode 8.0 character set, as well as 8 bit OEM character sets
- 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, supports both UTF8 and UTF16 encoded files
- 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
- Use TrueType fonts directly from the file without installing them first
Documentation
The manual is installed with the tool, but for those who wish to take a look at it without installing the tool first it is also available here. The manual describes both how to use the tool and the file format of the generated files.Source code
The source code is available under the widely known zlib license. The svn repository is hosted at SourceForge.net
Get the code by pointing your svn client at: http://svn.code.sf.net/p/bmfont/code/trunk. If you want any support with the code, then please visit the forums.

Observation on virus alert
Avira anti-virus has been known to give a virus alert when scanning bmfont.exe or the installer. This is a false positive generated by their heuristic functions that tries to predict and catch unknown viruses. I've already reported this false positive to Avira a few times and each time they recognize it as a false positive, however for some reason the problem comes back months later (presumably when they update the heuristic functions).If anyone has any idea what I need to change in the code to prevent this false alert I would very much like to know.

The following are some other tools that also generate output in the same format that I came up with for BMFont and that is widely used in the industry today.- Littera - free web application
- Glyph Designer - paid app for Mac
- ShoeBox - free tool written with Adobe Air
- Hiero - open source tool written in Java
