Hello everyone!
I'm a c# developer and I'm trying to create a windows Image Editor app. So analyze bitmap image in input and show a flexible histogram to modify that, then save as a new .jpg file.
My main doubt is this:
how do I create an histogram to modify the image in real time?

Thanks in advance

I don't know what that means. I've never seen an editor that allows interactive editing of a histogram. The usual arrangement (eg Gimp Color Curves) shows a histogram. The user can interactively edit curves, and Gimp will update the histogram accordingly.

snibgo -- perhaps he means like in Photoshop or GIMP where you can move sliders for clipping and stretching as per -level and +level

Exactly.
Does anyone know how to implement such a solution?
I had already looked at the scripts but the only problem is that they need Unix to work, right? (I'm working on a Windows-based application, with c#)

I'm still not sure what you are asking.

A program can be written in whatever language you want that reads sliders and applies effects to images, with updates to a screen copy of the image in real time. I have done that, with C and ImageMagick (unpublished). Gimp is open source, so you can see how it is done.
