Selecting certain parts of a image

[trig]

Hi,

I have this problem, i am uploading a .PNG image file and want I want to be able to do is to get my program to select certain parts of the image by it self.

For example, if i upload a PNG file with boxs, i want the program to be able to select the box's and ignore the background. This is so that if someone wanted to highlight just 1 box with a click, they can. Now the issue is getting the program to only selecting certain parts of the png file.

Any information would be great.

Thank you

You most probably need an image processing library, this one comes top in Google's "c++ image processing" search: http://cimg.sourceforge.net/
