out of curiosity, why do you want to alter the original image, rather than using css to add a single pixel border around a <img> tag?

Save your image in GIF-format as /tmp/logo.gif and run the following. Your "framed" image will be in /tmp/logo2.gif.




$im = ImageCreateFromGIF('/tmp/logo.gif');
   $rx = ImageSX($im)-1;
   $ry = ImageSY($im)-1;
   $tc = ImageColorAllocate($im, 255, 0, 0);

   $values = array(
      0, 0,
      $rx, 0,
      $rx, $ry,
      0, $ry,
      0, 0);

   ImagePolygon($im, $values, 5, $tc);
   ImageGIF($im, '/tmp/logo2.gif');
   ImageDestroy($im);

Open in new window

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

For jpg, just replace the GIF-functions with jpg equivalents:


$im = ImageCreateFromJPEG('/tmp/logo.jpg');
   $rx = ImageSX($im)-1;
   $ry = ImageSY($im)-1;
   $tc = ImageColorAllocate($im, 255, 0, 0);

   $values = array(
      0, 0,
      $rx, 0,
      $rx, $ry,
      0, $ry,
      0, 0);

   ImagePolygon($im, $values, 5, $tc);
   ImageJPEG($im, '/tmp/logo2.jpg');
   ImageDestroy($im);

I think I would choose CSS.  But the question is not complete.  Do you have a test image?  Please post one for us to use as test data.  Please tell us if you want the border to add to the size of the image or overwrite the existing order pixels.

If you are processing only a few images, you might just use Photoshop, too.

The author mentions the image should be saved on the server for future use. IMHO this indicates it is not an issue of modifying an image on-the-fly for a web server to be sent further but for something else. PHP, GD etc. can be and are used to perform off-line tasks too without any connection to web-servers, HTML or CSS.
