Parameters

$h_Image	Handle to an irrlicht image object
$i_XPos	X position on display from where drawing starts
$i_YPos	Y position on display from where drawing starts
$i_SourceTopX	X top position of rectangle in the source texture
$i_SourceTopY	Y top position of rectangle in the source texture
$i_SourceBottomX	X bottom position of rectangle in the source texture
$i_SourceBottomY	Y bottom position of rectangle in the source texture
$i_UseAlpha	Whether or not to use the alpha channel should be one of the following values: $IRR_IGNORE_ALPHA $IRR_USE_ALPHA

Success: True
Failure: False

local $logo = _IrrGetTexture("./media/cross.bmp")
_IrrColorKeyTexture($logo, 255, 255, 255)

WHILE _IrrRunning()
    _IrrBeginScene(50, 0, 0)
    _IrrDraw2DImageElement( $logo, 0, 0 , 0, 0, 128, 64, $IRR_IGNORE_ALPHA)
    _IrrDraw2DImageElement( $logo, 0, 64, 0, 64, 128, 128, $IRR_USE_ALPHA)
