imagecopymerge

(PHP 4 >= 4.0.1, PHP 5, PHP 7)
Copy and merge part of an image
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.

Returns:

Returns TRUE on success or FALSE on failure.

Examples:
Merging two copies of the PHP.net logo with 75% transparency
<?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);

imagedestroy($dest);
imagedestroy($src);
?>
