_GDIPlus_LineBrushMultiplyTransform

Updates a brush's transformation matrix with the product of itself and another matrix

#include <GDIPlus.au3>
_GDIPlus_LineBrushMultiplyTransform ( $hLineGradientBrush, $hMatrix [, $iOrder = 0] )

Parameters

$hLineGradientBrush Pointer to a LinearGradientBrush object
$hMatrix Pointer to a Matrix object that specifies the transformation matrix
$iOrder [optional] Order of matrices multiplication:
    0 - The passed matrix is on the left
    1 - The passed matrix is on the right

Return Value

Success: True.
Failure: False and sets the @error flag to non-zero, @extended may contain GPSTATUS error code error code ($GPIP_ERR* see GPIPlusConstants.au3).
