Does anybody know how to retrieve the gamma value from an bitmap. There is a function LBitmap::GammaCorrect() that can only set the gamma correction. What I want to do is to retrieve the current gamma setting of the bitmap then decide which value I need to put to correct it.

Thanks!

There is no function that retrieves the gamma value set by GammaCorrect. We only have a GetPaintGamma/SetPaintGamma pair. Those only affect the display of the image but not the pixel data as opposed to GammaCorrect.

When an image is loaded, the Gamma has not be adjusted at all. LEADTOOLS loads the image as the data is stored in the file.
