While this is cool, I think it would be better to write a set of convertors to and from well-recognised formats like BDF. There are far more professional tools that work with those, e.g. gbdfed, FontForge and Bits'N'Picas:

Thanks for sharing that, I'll have a read. Knowing very little on the subject, I was missing the keywords to duck-duck-go for to find any info on the topic of generating font sprites for embedded systems.

I myself had written a tool like yours for a similar purpose except I needed it done quick'n'dirty, so I wrote it in C with GTK and just used a grid of toggle buttons :D

It all went fine until I needed a variable width modern-looking font, so I wrote a convertor from BDF to the proprietory format the video chip used (vertical middle-endian scan lines arranged in a weird order) and generated the BDF using gbdfed or FontForge, I don't remember which one. I must admit the convertor was horrible :D

Interestingly enough, when I needed fonts/sprites again in a couple of years, I resorted to a set of multi-layer GIMP files with a set of rulers and grids which I would export into the X bitmap format (which is a text format consisting of a bunch of C constants). (I didn't need to dynamically generate text on that project, just fixed pre-prepared strings.)
