Updates a matrix with the product of itself and a rotation matrix
#include <GDIPlus.au3>
_GDIPlus_MatrixRotate ( $hMatrix, $fAngle [, $bAppend = False] )
$hMatrix | Handle to a Matrix object |
$fAngle | The angle of rotation in degrees. Positive values specify clockwise rotation. |
$bAppend | [optional] Specifies the order of the multiplication: True - Specifies that the rotation matrix is on the left False - Specifies that the rotation matrix is on the right |
Success: | True. |
Failure: | False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code ($GPIP_ERR* see GPIPlusConstants.au3). |
