Retrieves the RGB color value of the pixel at the point specified by x and y.
Specifies the logical x-coordinate of the point to be examined.
Specifies the logical y-coordinate of the point to be examined.
Specifies the logical x- and y-coordinates of the point to be examined.
For either version of the function, an RGB color value for the color of the given point. It is –1 if the coordinates do not specify a point in the clipping region.
The point must be in the clipping region. If the point is not in the clipping region, the function has no effect and returns –1.
Not all devices support the GetPixel function. For more information, see the RC_BITBLT raster capability under the GetDeviceCaps member function.
