Verify ImageMagick installation

Try this:

<?php
//This function prints a text array as an html list.
function alist ($array) {  
  $alist = "<ul>";
  for ($i = 0; $i < sizeof($array); $i++) {
    $alist .= "<li>$array[$i]";
  }
  $alist .= "</ul>";
  return $alist;
}
//Try to get ImageMagick "convert" program version number.
exec("convert -version", $out, $rcode);
//Print the return code: 0 if OK, nonzero if error. 
echo "Version return code is $rcode <br>"; 
//Print the output of "convert -version"    
echo alist($out); 
?>

You have to add extension=imagick.so in your php.ini file.

• Location:

You can do some thing like this for the fastest way:

php -i | grep 'php.ini'

The result is like that:

Loaded Configuration File => /usr/local/lib/php.ini

Or call <?php phpinfo(); ?> from some php file to get this information :)

PS: Source

I am hopeless at PHP but something like this seems to work for me:

#!/usr/local/bin/php -f
<?php

   $padding=10;
   $info = getimagesize("input.jpg");
   $width=$info[0];
   $height=$info[1];

   // Calculate dimensions of output image
   $canvasWidth=$width+4*$padding;
   $canvasHeight=$height+2*$padding;

   // create white canvas
   $output = imagecreatetruecolor($canvasWidth, $canvasHeight);
   $background = imagecolorallocate($output, 255, 255, 255);
   imagefill($output, 0, 0, $background);

   // read in original image
   $orig = imagecreatefromjpeg("input.jpg");

   // copy left third to output image
   imagecopy($output, $orig,$padding,             $padding,             0, 0, $width/3, $height);
   // copy central third to output image
   imagecopy($output, $orig,2*$padding+$width/3,  $padding,      $width/3, 0, $width/3, $height);
   // copy right third to output image
   imagecopy($output, $orig,3*$padding+2*$width/3,$padding,    2*$width/3, 0, $width/3, $height);

   // save output image
   imagejpeg($output,"result.jpg");
?>

If I start with this:

I get this as a result

I added the black outline afterwards so you can see the extent of the image.
