Updates the world transformation matrix of a Pen object with the product of itself and a rotation matrix
#include <GDIPlus.au3>
_GDIPlus_PenRotateTransform ( $hPen, $fAngle [, $iOrder = 0] )
| $hPen | A pointer to a Pen object. |
| $fAngle | The angle, in degrees, of rotation |
| $iOrder | [optional] An order of matrices multiplication: 0 - The passed matrix is on the left 1 - The passed matrix is on the right |
| Success: | True. |
| Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
