I use a program that produce a graphic (imagine a sinusoid, more or less).
There is no opportunity to obtain from the program an output of the coordinates of the points of this curve.
I desperately tried a way to achieve this, for example using a program that transform a normal raster image in a vector, and after read the vector, but all this is not precise nor accurate.
I wonder if there is a way to obtain this result.

If I'm reading this right, you want to take a picture, analyse it, and pull out things like a point on the curve, curve angle, etc. Correct?

This won't be easy. If you are using C/C++, this will be pretty hard (as in, probably on the level of just recreating the program itself). It might be doable in Matlab or some other language with loads of image manipulation libraries.

Heck, it may even be possible (and easier) to inject a DLL to spit out the info you need http://en.wikipedia.org/wiki/DLL_injection

Maybe inject a DLL could be a solution.
Now I'm reading the topic... I download "UniJect - A universal DLL injector" from the site http://warpzone.se/uniject.php, and I'll tried to build a DLL.
