Re: [Dev-C++] Drawing lines

Hello everyone,

I have copied the following from the Windows API help files. Does it help?

-----------------------------------------

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
   );


Parameters

hdc

Identifies the device context.

X

Specifies the x-coordinate, in logical units, of the point to be set.

Y

Specifies the y-coordinate, in logical units, of the point to be set.

crColor

Specifies the color to be used to paint the point.

Return Values

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.

Remarks

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.

Regards,
        Kevin.
