	      imagepolygon(3) example

	      <?php

	      $image = imagecreatetruecolor(400, 300);

	      // Allocate a color for the polygon
	      $col_poly = imagecolorallocate($image, 255, 255, 255);

	      // Draw the polygon

		      0,   0,
		      100, 200,
		      300, 200
		  ),
		  3,
		  $col_poly);
