imagecopymerge
(PHP 4 >= 4.0.1, PHP 5, PHP 7)
imagecopymerge — Copy and merge part of an image
Description
bool imagecopymerge ( resource $dst_im , resource $src_im , int $dst_x , int $dst_y , int $src_x , int $src_y , int $src_w , int $src_h , int $pct ) Copy a part of src_im onto dst_im starting at the x,y coordinates src_x, src_y with a width of src_w and a height of src_h. The portion defined will be copied onto the x,y coordinates, dst_x and dst_y.
Parameters
dst_im
Destination image link resource.
src_im
Source image link resource.
dst_x
x-coordinate of destination point.
dst_y
y-coordinate of destination point.
src_x
x-coordinate of source point.
src_y
y-coordinate of source point.
src_w
Source width.
src_h
Source height.
pct
The two images will be merged according to pct which can range from 0 to 100. When pct = 0, no action is taken, when 100 this function behaves identically to imagecopy() for pallete images, except for ignoring alpha components, while it implements alpha transparency for true colour images.
Return Values
Returns TRUE on success or FALSE on failure.
Examples

<?php
// Create image instances
$dest = imagecreatefromgif('php.gif');
$src = imagecreatefromgif('php.gif');
// Copy and merge
imagecopymerge($dest, $src, 10, 10, 0, 0, 100, 47, 75);
// Output and free from memory
header('Content-Type: image/gif');
imagegif($dest);
