imagecopymerge

Copy and merge part of an image

&reftitle.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`.

&reftitle.parameters;

`dst_im`

- &gd.image.destination;

`src_im`

- &gd.image.source;

`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`

- &gd.source.width;

`src_h`

- &gd.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.

&reftitle.returnvalues;

&return.success;

### 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);
    ?>
