#include "BIFILTER.H"
HANDLE CALLBACK HistDIBEqualization( HANDLE hSrcDIB,
int iShowProgress,
HWND hParent)
Description
The result is put to a newly created DIB and the source DIB is unmodified. The result DIB has a uniform histogram. It works with 4, 8 or 24 bits/pixel. In case of 24 bits/pixel, the operation is made separately on the R, G, B channels. In case of 4 or 8 bits/pixel, the source DIB must contain grayscale image and the palette values in the source DIB must be monotone increasing. It makes no sense to use this function in case of 1 bits/pixel.
