# imagecopymerge

(PHP 4 >= 4.0.1, PHP 5)

imagecopymerge — Copy and merge part of an image

### Beschreibung

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`.

### Parameter-Liste

`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, while it implements alpha transparency for true colour images.

### Rückgabewerte

Gibt bei Erfolg `TRUE` zurück. Im Fehlerfall wird `FALSE` zurückgegeben.

### Beispiele

Beispiel #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);
?>`
