The ColorBalance method changes the overall mixture of colors in the image page for generalized color correction based on defined values for each of the valid channels available - Red, Green and Blue.
Syntax
HRESULT ColorBalance([in, defaultvalue(0)] LONG nRValue,
[in, defaultvalue(0)] LONG nGValue,
[in, defaultvalue(0)] LONG nBValue,
[in, defaultvalue(NULL)] RECT* stRect);
Parameters
- nRValue
- [in, defaultvalue(0)] Specifies the level of red color in the image.
- nGValue
- [in, defaultvalue(0)] Specifies the level of green color in the image.
- nBValue
- [in, defaultvalue(0)] Specifies the level of blue color in the image.
- stRect
- [in, defaultvalue(NULL)] Pointer to RECT structure which defines the rectangular area where function should be applied. If this parameter is NULL, the entire page will be processed.
Note:
Please note that partial processing of an area of a page is not supported for all image formats. For example, it is not supported for indexed images, because each pixel in such images does not contain a color, but an index into a color table (or palette) which is common for the entire page.Return Value
Returns S_OK if operation was successful or error code in other cases.
