View Full Version : from screen to file

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.

Why not just capture the screen image? 100's of programs that do that.

Yes, but after I have to extract the numbers (= the coordinates x,y of the numbers).
I also tried to recode with XnView in ppm (ASCII format) and try to obtain something, but it was a pain; definitely it is not the right way...
In any case I have FTPed here the jpeg:
