imageaffinematrixconcat — Concatenate two affine transformation matrices
Description
Returns the concatenation of two affine transformation matrices, what is useful if multiple transformations should be applied to the same image in one go.
Parameters
-
matrix1 -
An affine transformation matrix (an array with keys
0to5and float values). -
matrix2 -
An affine transformation matrix (an array with keys
0to5and float values).
Return Values
An affine transformation matrix (an array with keys
0 to 5 and float values)
or false on failure.
Examples
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);
?>The above example will output:
Array
(
[0] => 4
[1] => 0
[2] => 0
[3] => 5
[4] => 8
[5] => 15
)
