[texhax] Incorporating TeX into Custom-made Programs

How do you suggest that I incorporate TeX symbols
into a graphical C program?
Displaying individual symbols would be doable by simply using the
freetype library to read the TeX math fonts and display characters from
them. However, I imagine you actually need to typeset significant
mathematical equations/formulas, which is a much harder problem.
The other replies mostly suggested creating a (La)TeX document and
processing it into a png/pdf/whatever, and displaying that. That seems
like the most expedient solution to me too.
However, I wanted to mention the (much) more difficult but (much) more
efficient solution of typesetting the math yourself. The algorithm is
described in Appendix G of the TeXbook, and of course the source is in
tex.web. It was also reimplemented in C++ by Luca Padovani for his
GtkMathView project, which applies TeX math typesetting to MathML input.
By the way, we'd certainly welcome an article on your project (or the
others people have mentioned in this thread) for TUGboat, when the time
is appropriate. (http://tug.org/TUGboat)
