Returns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.

Parameters

m1

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

Examples

Example #1 imageaffinematrixconcat() 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);
?>

The above example will output:

Array
(
    [0] => 4
    [1] => 0
    [2] => 0
