		image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3).

	      o $points
		- An array containing the polygon's vertices, e.g.:

	      +----------+------+
	      |points[0] |	|
	      | 	 |	|
	      | 	 | = x0 |
	      | 	 |	|
	      |points[1] |	|
	      | 	 |	|
	      | 	 | = y0 |
	      | 	 |	|
	      |points[2] |	|
	      | 	 |	|
	      | 	 | = x1 |
	      | 	 |	|
	      |points[3] |	|
	      | 	 |	|
	      | 	 | = y1 |
	      | 	 |	|
	      +----------+------+
	      o $num_points
		- Total number of points (vertices).

	      o $color
		- A color identifier created with imagecolorallocate(3).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	      <?php
	      // Create a blank image
	      $image = imagecreatetruecolor(400, 300);

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

	      // Draw the polygon
	      imagepolygon($image, array(
		      0,   0,
		      100, 200,
		      300, 200
		  ),
		  3,
		  $col_poly);

	      // Output the picture to the browser
	      header('Content-type: image/png');

	      imagepng($image);
	      imagedestroy($image);
	      ?>

	      $php = imagecreatefrompng('./php.png');

	      // Create the main image, 100x100
	      $im = imagecreatetruecolor(100, 100);

	      // Fill the background with white
	      $white = imagecolorallocate($im, 255, 255, 255);
	      imagefilledrectangle($im, 0, 0, 299, 99, $white);

	      // Set the brush
	      imagesetbrush($im, $php);

	      // Draw a couple of brushes, each overlaying each
	      imageline($im, 50, 50, 50, 60, IMG_COLOR_BRUSHED);

	      // Output image to the browser
	      header('Content-type: image/png');

	      imagepng($im);
	      imagedestroy($im);
	      imagedestroy($php);

NOTES

       Note

	       You need not take special action when you are finished with a brush, but if you destroy the brush  image,  you  must  not  use  the
	      IMG_COLOR_BRUSHED or IMG_COLOR_STYLEDBRUSHED colors until you have set a new brush image!
