imageaffinematrixconcat — Concatenate two affine transformation matrices
설명
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.
인수
-
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).
반환값
An affine transformation matrix (an array with keys
0 to 5 and float values)
실패 시 FALSE를 반환합니다.
예제
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);
?>
위 예제의 출력:
Array
(
[0] => 4
[1] => 0
[2] => 0
[3] => 5
[4] => 8
[5] => 15
)
참고
- imageaffine() - Return an image containing the affine transformed src image, using an optional clipping area
- imageaffinematrixget() - Get an affine transformation matrix
