EXAMPLES

       Example #1

	      Outputting a JPEG image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Set the content type header - in this case image/jpeg
	      header('Content-Type: image/jpeg');

	      // Output the image
	      imagejpeg($im);

	      // Free up memory
	      imagedestroy($im);
	      ?>

       Example #2

	      Saving a JPEG image

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Save the image as 'simpletext.jpg'
	      imagejpeg($im, 'simpletext.jpg');

	      // Free up memory
	      imagedestroy($im);
	      ?>

       Example #3

	      Outputting the image at 75% quality

	      <?php
	      // Create a blank image and add some text
	      $im = imagecreatetruecolor(120, 20);
	      $text_color = imagecolorallocate($im, 233, 14, 91);
	      imagestring($im, 1, 5, 5,  'A Simple Text String', $text_color);

	      // Set the content type header - in this case image/jpeg
	      header('Content-Type: image/jpeg');

	      // Skip the filename parameter using NULL, then set the quality to 75%
	      imagejpeg($im, NULL, 75);

	      // Free up memory
	      imagedestroy($im);
	      ?>

NOTES

       Note

	      JPEG support is only available if PHP was compiled against GD-1.8 or later.

       Note

	       If you want to output Progressive JPEGs, you need to set interlacing on with imageinterlace(3).
