Updates a brush's transformation matrix with the product of itself and another matrix
#include <GDIPlus.au3>
_GDIPlus_PathBrushMultiplyTransform ( $hPathGradientBrush, $hMatrix [, $iOrder = 0] )
| $hPathGradientBrush | Pointer to a PathGradientBrush object |
| $hMatrix | Pointer to a matrix to be multiplied by the brush's current transformation matrix |
| $iOrder | [optional] Order of matrices multiplication: 0 - The passed matrix is on the left 1 - The passed matrix is on the right |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
None.
