If anyone volunteered for a TTF library X platform, we could make that thing with GLBasic.
Also, the project libgd seems to have a console program that can print on a png image. So, that might be a x-platform way to solve this.
Hi mate, did you mean FreeType (http://freetype.sourceforge.net/index2.html
)? The only downside with FreeType is that it's not really a font renderer. Reading the FAQ it makes it quite clear that although it can do basic rendering (1-bit mono and 8-bit grey scale) of fonts, it's not a graphics library. It doesn't even handle formatting such as justification, kerning etc. It's more a library that allows you to read in fonts and not a lot more.
There is also SDL_ttf 2.0 (http://www.libsdl.org/projects/SDL_ttf/
) which uses FreeType 2.0.
Only other option would be to recreate the Windows version of the font tool for Mac. If it was left up to me, I'd probably "cheat" and use PureBASIC to recreate it for Windows, Mac and Linux (assuming there was ever a Linux editor).
Edit: Removed one of my more daft suggestions.
