L_LTIMGEFX_API L_INT L_MatchHistogram(pBitmap, pRefBitmap, uFlags)
Parameters
pBITMAPHANDLE pBitmap
Pointer to the bitmap handle that references the bitmap on which to apply the effect.
pBITMAPHANDLE pRefBitmap
Pointer to the bitmap handle that references the bitmap which its histogram will be a reference for matching.

Returns
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
Comments
This function supports 8-bit grayscale and 24-bit color images.
If the image to be transformed is 8-bit grayscale then the reference image must be 8-bit grayscale too. If the image to be transformed is 24-bit color, then the reference image could be 8-bit grayscale or 24-bit color.
