DWORD GetPixel(hDC,X,Y)
This function retrieves the RGB color value of the pixel at the point specified by the X and Y parameters. The point must be in the clipping region. If the point is not in the clipping region, the function is ignored.
| Parameter | Type/Description |
| hDC | HDC Identifies the device context. | |
| X | int Specifies the logical x-coordinate of the point to be examined. | |
| Y | int Specifies the logical y-coordinate of the point to be examined. |
The return value specifies 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.
Not all devices support the GetPixel function. For more information, see the RC_BITBLT raster capability in the GetDeviceCaps function, earlier in this chapter.
