matrix2 An affine transformation matrix (an array with keys to and float values). 0``5

An affine transformation matrix (an array with keys to and float values) return.falseforfailure. 0``5

Voorbeeld: example

<?php
$m1 = imageaffinematrixget(IMG_AFFINE_TRANSLATE, array('x' => 2, 'y' => 3));
$m2 = imageaffinematrixget(IMG_AFFINE_SCALE, array('x' => 4, 'y' => 5));
$matrix = imageaffinematrixconcat($m1, $m2);
print_r($matrix);
?>
