imageaffinematrixconcat — Concatenate two affine transformation matrices
说明
imageaffinematrixconcat
( array $m1
, array $m2
) : array|false
Returns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.
参数
m1- An affine transformation matrix (an array with keys
0to5and float values). m2- An affine transformation matrix (an array with keys
0to5and float values).
返回值
An affine transformation matrix (an array with keys
0 to 5 and float values)
或者在失败时返回 false.
范例
Example #1 imageaffinematrixconcat() example
<?php$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
)
