Updates the clipping region of a Graphics object to a region that is the combination of itself and a rectangle
#include <GDIPlus.au3>
_GDIPlus_GraphicsSetClipRect ( $hGraphics, $nX, $nY, $nWidth, $nHeight [, $iCombineMode = 0] )
| $hGraphics | Pointer to a Graphics object |
| $nX | X coordinate of the upper-left corner of the rectangle |
| $nY | Y coordinate of the upper-left corner of the rectangle |
| $nWidth | Width of the rectangle |
| $nHeight | Height of the rectangle |
| $iCombineMode | [optional] Regions combination mode: 0 - The existing region is replaced by the new region 1 - The existing region is replaced by the intersection of itself and the new region 2 - The existing region is replaced by the union of itself and the new region 3 - The existing region is replaced by the result of performing an XOR on the two regions 4 - The existing region is replaced by the portion of itself that is outside of the new region 5 - The existing region is replaced by the portion of the new region that is outside of the existing region |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
