imagecopymerge — Copy and merge part of an image
$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.
dst_imDestination image link resource.
src_imSource image link resource.
dst_xx-coordinate of destination point.
dst_yy-coordinate of destination point.
src_xx-coordinate of source point.
src_yy-coordinate of source point.
src_wSource width.
src_hSource 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 TRUE on success or FALSE on failure.
Example #1 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);
?>
