_GDIPlus_MatrixSetElements ( $hMatrix [, $nM11 = 1 [, $nM12 = 0 [, $nM21 = 0 [, $nM22 = 1 [, $nDX = 0 [, $nDY = 0]]]]]] )

Parameters

$hMatrix A handle value
$nM11 [optional] A floating point number value. Default is 1
$nM12 [optional] A floating point number value. Default is 0
$nM21 [optional] A floating point number value. Default is 0
