(PHP 5 >= 5.5.0, PHP 7)

imageaffinematrixconcat — Concatenate two affine transformation matrices

### 说明

imageaffinematrixconcat ( array `$m1` , array `$m2` ) : array

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

`m1`

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

`m2`

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

### 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`.

### 范例

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);
    ?>

以上例程会输出：

    Array
    (
        [0] => 4
        [1] => 0
        [2] => 0
        [3] => 5
        [4] => 8
        [5] => 15
    )
