The SetPixel function sets the pixel at the specified coordinates to the specified color.
COLORREF SetPixel(
HDC hdc, |
// handle of device context |
int X, |
// x-coordinate of pixel |
int Y, |
// y-coordinate of pixel |
COLORREF crColor |
// pixel color |
); |
If the function succeeds, the return value is the RGB value that the function sets the pixel to. This value may differ from the color specified by crColor; that happens when an exact match for the specified color cannot be found.
If the function fails, the return value is -1. To get extended error information, call GetLastError.
The function fails if the pixel coordinates lie outside of the current clipping region.
Not all devices support the SetPixel function. For more information, see GetDeviceCaps.
