#include <GDIPlus.au3>
_GDIPlus_BitmapCreateApplyEffect ( $hBitmap, $hEffect [, $tRECT = Null [, $tOutRECT = Null]] )
| $hBitmap | Handle to a Bitmap to which the effect is applied. |
| $hEffect | Handle to an Effect to be applied. |
| $tRECT | [optional] a $tagRECT structure that specifies the portion of the input bitmap that is used. |
| $tOutRECT | [optional] a $tagRECT structure that receives the portion of the input bitmap that was used. |
| Success: | a handle to a Bitmap object. |
| Failure: | 0 and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
