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

参数

matrix1

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

matrix2

返回值

An affine transformation matrix (an array with keys 0 to 5 and float values) 或者在失败时返回 false.

示例

示例 #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);
?>

以上示例会输出:

Array
(
    [0] => 4
    [1] => 0
    [2] => 0
    [3] => 5
    [4] => 8
