Re: [Freetype-devel] Re: GSOC - Distance Fields

I agree with Alexei that it's probably a good idea to start writing a prototype with whatever language / format you feel the more fluent first so we can look at the algorithms and the outputted data.

This can later be rewritten into something more FreeType-specific (e.g. fixed-floats are better than floats if you have simple ranges like [-1.0..1.0] in general).

Great! Without further delay, go ahead and write a standalone program
that calculates DF for a outline glyph in whatever format you choose
or is appropriate. This is a lot of work by itself. How are you going
to calculate it straight from Bezier outlines should concern you much
more than memory issues.

We can think about integrating it into FreeType ,once you have a
standalone implementation.
