Converting fonts to images and back

[anthony]

Creating font files (which are vector images) is beyond the scope of IM, which is a raster image processor.
For the differences see
A word about Vector Image formats

However various people have been scanning and vectorizing raster images to generate fonts for various things. Look at Autotrace, and Potrace as starting points for this. I am sure google can find you information and techniques these people use.

You may even be able to find a actual vector editor that can modify the font as vectors.
