I want an image to move according to the path drawn by programming codes. I have asked a similar question (http://stackoverflow.com/questions/1571182/how-to-limit-a-uiimageview-to-move-in-a-specific-path) before, but I found that I asked in a wrong way.

I have a library that draws regular bezier path figures (complex paths formed of a lot of bezier points), using midpoint approximation. I can draw them without problem, but I need to add support for advanced geometry operations: Nearest point of a curve, intersection, figure contains point, and more importantly, path combinations: diffe...
I have a bezier path library to draw complex bezier paths without problem. Now, I need to know how to read a text or font and extract its path information to draw it as a path instead of as text. I came across a C applicaiton, FontForge. It does exactly what I need, picks any font and extract its path information. But what I need to kno...
