I need to make a program that can retrieve the width of lines and put it into a histogram. Same thing with the height of lines, but a seperate histogram. I've already looked into histograms and I know how to do those ( I'm using C# for that ). Its how to retrieve the width and height of all the different lines. I need to read off of a chart like what I'm showing from imageshack. If anyone can help, that would be excellent!

I would REALLY appreciate it if someone could help me out!!!
