imageaffinematrixconcat — Concatenate two affine transformation matrices

### Descrierea

imageaffinematrixconcat ( array `$m1` , array `$m2` ) : array

Returns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.

### Parametri

`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).

### Valorile întoarse

An affine transformation matrix (an array with keys 0 to 5 and float values) sau `FALSE` în cazul eșecului.

### Exemple

$m2 = imageaffinematrixget(IMG_AFFINE_SCALE, array('x' = 4, 'y' => 5));
$matrix = imageaffinematrixconcat($m1, $m2);
print_r($matrix);
?>`
