imageaffinematrixconcat

(PHP 5 >= 5.5.0, PHP 7)

imageaffinematrixconcatConcatenate two affine transformation matrices

说明

array imageaffinematrixconcat ( array $m1 , array $m2 )

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
)
