imageaffinematrixconcat — Concatenate two affine transformation matrices
Description
array imageaffinematrixconcat ( array $m1 , array $m2 )
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
-
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).
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
)
