imageaffinematrixconcat — Concatenate two affine transformation matrices
Beschreibung
$matrix1
, array $matrix2
): array|falseReturns 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
to5
and float values). -
matrix2
-
An affine transformation matrix (an array with keys
0
to5
and float values).
Rückgabewerte
An affine transformation matrix (an array with keys
0

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 )
