int $src_y
,
int $src_width

int $pct
)
Parameters
-
dst_image
-
Destination image resource.
-
src_image
-
Source image 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_width
-
Source width.
-
src_height
-
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);
imagedestroy($dest);
imagedestroy($src);
?>
