#Include <au3Irrlicht2.au3>
_IrrDraw2DImageElement($h_Texture, $i_XPos, $i_YPos, $i_SourceTopX, $i_SourceTopY, $i_SourceBottomX, $i_SourceBottomY, $i_UseAlpha)
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 |
Return Value
Success: TrueFailure: False
