imageaffinematrixconcat — Concatenate two affine transformation matrices
$matrix1, array $matrix2): array|false
Returns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.
matrix1
An affine transformation matrix (an array with keys
0 to 5 and float values).
matrix2
An affine transformation matrix (an array with keys
0 to 5 and float values).
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 #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
)
