LPDRAWMODE lpDrawMode; |
The Pixel function sets or retrieves the color of the specified pixel. The function sets the given pixel to the color given by the dwPhysColor parameter if the lpDrawMode parameter specifies a binary-raster operation. Pixel returns the physical color of the pixel if the lpDrawMode parameter is NULL. GDI calls this function when simulating output or when an application calls the SetPixel or GetPixel function (GDI.31 or GDI.83).
Every graphics driver must export a Pixel function.
lpDestDev
Points to a PDEVICE or PBITMAP structure specifying the destination device or bitmap.
X
Specifies the x-coordinate of the pixel to retrieve or set.
Y
Specifies the y-coordinate of the pixel to retrieve or set.
dwPhysColor
Specifies the physical color value used to set the pixel.
lpDrawMode
Points to a DRAWMODE structure specifying the binary-raster operation to use to combine the physical color with the existing pixel color.
If lpDrawMode is NULL, Pixel retrieves and returns the current color of the specified pixel.
The return value is either the physical color of the specified pixel or 1 depending on whether lpDrawMode is NULL, if the function is successful. Otherwise, the function returns 0x80000000L.
The export ordinal for this function is 9.
