Leonardo: The RWSetPixelIndex function

This function sets a pixel at the specified x-y coordinates to the binary pixel value in the lpPixelIndex structure.

void API RWSetPixelIndex(
HDIBRW	hDibRW,
int	x,
int	y 
LPRIXELINDEXUNTION	lpPixelIndexUnion);

hDibRW HDIBRW Handle for DIB access returned by RWOpenDIB

x int Horizontal coordinate of the pixel to be set; i.e. the number of the pixels from the left edge of the DIB to the desired pixel.

y int Vertical coordinate of the pixel to be set; i.e. the number of the pixels from the bottom edge to the desired pixel. (0 in this function points to the bottom row of pixels, rather than the top row.)

lpPixelIndexUnion LPPIXELINDEXUNION Pointer to a PIXELINDEXUNION - structure defining the binary pixel value for the pixel.
