Hello,

I would like to create an contrast adjustment tool similar to incontrast() function that can adjust contrast by dragging the histogram bars. I cannot use imcotrast because I want to use the histogram in a gui. Can anyone please give me some hint how can I start making this tool?

Thanks in advance

You're asking for a graphical image adjustment tool while simultaneously asserting that you can't use the extant ones because you want to make your own tool.

There are other interactive tools for doing image adjustment. MIMT has immodify(), and IPT has imcontrast(), but that's really irrelevant. If your goal is to reinvent the wheel, then reinvent the wheel.
