imageaffinematrixconcat — Concatenate two affine transformation matrices
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) Bei einem Fehler wird false zurückgegeben..
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 )
