DotImage 1.2 introduces a number of commands that can be used to correct color in images. They include:
Levels
Auto Levels
Auto Color
Auto Contrast
These commands work just like Adobe Photoshop. This code includes a C# project with a Levels dialog that looks and acts just like Photoshop's version. It uses the histogram functions in DotImage to show the histogram and the new Levels and Auto Levels commands.
This dialog could use some "touching up". If you would like to do so, feel free to post the results here. It also could use a VB.NET version.
