imageaffinematrixconcat — Concatenate two affine transformation matrices

Beschreibung

imageaffinematrixconcat(array $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.

Parameter-Liste

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).

Rückgabewerte

An affine transformation matrix (an array with keys 0 to 5 and float values) Bei einem Fehler wird false zurückgegeben..

Beispiele

Beispiel #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);
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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