Peter asked me to forward his auto spacing idea to the ttfautohint and
fontforge devel lists :-)

Dear Sir,

I am also working with fonts, and I found, that kerning it's a very
time-consuming job, especially with the font that have a lot of
glyphs. I often have seen fonts, that has a good kerning for all that
ANSI-leters, but the poor or even nonexisting kerning for all the
Unicode letters, and so I have the idea for another tool likeĀ  you're
fantastic ttfautohint.

I think, that could work like this: the software has to build and you
conture around any glyphe, in a way that the distance to the outline
of the glyphe is depending on its form, so that theĀ  new outline is
closer to sharp edges then to straight lines. this could be done in
the way I have described in the attached graphic.

First I have made a pixel copy of my letters. Then I have blurred this
little picture and after that I had reduced all the gray pixels to
black. this new picture can be traced, so I get a new outline around
my glyphes. The next step is to move all the glyphs to gether, until
the new outline we get in touch, so it must be possible to calculate a
good value for this kerning pair. this could be done automatically
with all glyphs in the font, or even with all possible combinations in
any language.

I hope that you understand me. Please let me know about your thinking
on this idea.

With kind regards
Peter Wiegel
