imagecopymerge - Copy and merge part of an image

SYNOPSIS

       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)

DESCRIPTION

	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

	      o $dst_im
		-Destination image link resource.

	      o $src_im
		-Source image link resource.

	      o $dst_x
		- x-coordinate of destination point.

	      o $dst_y
		- y-coordinate of destination point.

	      o $src_x
		- x-coordinate of source point.

	      o $src_y
		- y-coordinate of source point.

	      o $src_w
		-Source width.

	      o $src_h
		-Source height.

	      o $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(3) 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

       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);
	      ?>

	      imagepalettecopy(3) example

	      <?php

	      $palette1 = imagecreate(100, 100);
	      $palette2 = imagecreate(100, 100);

	      // Allocate the background to be
	      // green in the first palette image
	      $green = imagecolorallocate($palette1, 0, 255, 0);

	      // Copy the palette from image 1 to image 2
	      imagepalettecopy($palette2, $palette1);

	      // Since the palette is now copied we can use the
	      // green color allocated to image 1 without using
	      // imagecolorallocate() twice
	      imagefilledrectangle($palette2, 0, 0, 99, 99, $green);

	      // Output image to the browser
