virtual L_INT LBitmap::ChannelMix(pRedFactor, pGreenFactor, pBlueFactor, uFlags = 0)
Redistributes the RGB values of the specified bitmap, using the values stored in the specified structures.
Pointer to a COLORDATA structure that contains the values to use for redistributing the bitmap's red values.
Pointer to a COLORDATA structure that contains the values to use for redistributing the bitmap's green values.
Pointer to a COLORDATA structure that contains the values to use for redistributing the bitmap's blue values.
Reserved for future use. Must be 0.

SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This function is used to rebalance the colors in a bitmap. It can be used to make color adjustments and corrections.
This function supports 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 24- and 48-bit bitmaps and can support regions for 24- and 48-bit bitmaps. If the bitmap has a region, the effect will be applied on the region only.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
Win32, x64.
The following example applies the LBitmap::ChannelMix function to it:
L_INT LBitmap__ChannelMixExample(LAnimationWindow *BitmapWindow)
{
COLORDATA RedFact, GreenFact, BlueFact;
RedFact.uStructSize = sizeof(COLORDATA);
GreenFact.uStructSize = sizeof(COLORDATA);
BlueFact.uStructSize = sizeof(COLORDATA);
RedFact.nRedFactor = 250;
RedFact.nGreenFactor = 255;
RedFact.nBlueFactor = 222;
RedFact.nConstant = 0;
GreenFact.nRedFactor = 100;
GreenFact.nGreenFactor = 0;
GreenFact.nBlueFactor = 250;
GreenFact.nConstant = 0;
BlueFact.nRedFactor = 5;
BlueFact.nGreenFactor = 0;
BlueFact.nBlueFactor = 0;
BlueFact.nConstant = 0;
return BitmapWindow->ChannelMix( &RedFact, &GreenFact, &BlueFact);
}
