The GetPixel function retrieves the red, green, blue (RGB) color value of the pixel at the specified coordinates.
COLORREF GetPixel(
HDC hdc, |
// handle of device context |
int XPos, |
// x-coordinate of pixel |
int nYPos |
// y-coordinate of pixel |
); |
The return value is the RGB value of the pixel. If the pixel is outside of the current clipping region, the return value is CLR_INVALID.
The pixel must be within the boundaries of the current clipping region.
Not all devices support GetPixel. An application should call GetDeviceCaps to determine whether a specified device supports this function.
