Verify ImageMagick installation

Question

My web hosting said ImageMagic has been pre-installed on the server. I did a quick search for \"ImageMagick\" in the output of phpinfo() and I found nothing. I can\'t SSH in

Answer 1

This is as short and sweet as it can get:

if (!extension_loaded('imagick'))
    echo 'imagick not installed';

Answer 2

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); 
?>

Answer 3

To test only the IMagick PHP extension (not the full ImageMagick suite), save the following as a PHP file (testImagick.php) and then run it from console: php testImagick.php

<?php
$image = new Imagick();
$image->newImage(1, 1, new ImagickPixel('#ffffff'));
$image->setImageFormat('png');
$pngData = $image->getImagesBlob();
echo strpos($pngData, "\x89PNG\r\n\x1a\n") === 0 ? 'Ok' : 'Failed';
echo "\n";

EDIT: The info and script below only applies to iMagick class - which is not added by default with ImageMagick!!!

If I want to know if imagemagick is installed and actually working as a php extension, I paste this snippet into a web accessible file

<?php

error_reporting(E_ALL); 
ini_set( 'display_errors','1');

/* Create a new imagick object */
$im = new Imagick();

/* Create new image. This will be used as fill pattern */
$im->newPseudoImage(50, 50, "gradient:red-black");

/* Create imagickdraw object */
$draw = new ImagickDraw();

/* Start a new pattern called "gradient" */
$draw->pushPattern('gradient', 0, 0, 50, 50);

/* Composite the gradient on the pattern */
$draw->composite(Imagick::COMPOSITE_OVER, 0, 0, 50, 50, $im);

/* Close the pattern */
$draw->popPattern();

/* Use the pattern called "gradient" as the fill */
$draw->setFillPatternURL('#gradient');

/* Set font size to 52 */
$draw->setFontSize(52);

/* Annotate some text */
$draw->annotation(20, 50, "Hello World!");

/* Create a new canvas object and a white image */
$canvas = new Imagick();
$canvas->newImage(350, 70, "white");

/* Draw the ImagickDraw on to the canvas */
$canvas->drawImage($draw);

/* 1px black border around the image */
$canvas->borderImage('black', 1, 1);

/* Set the format to PNG */
$canvas->setImageFormat('png');

/* Output the image */
header("Content-Type: image/png");
echo $canvas;
?>

You should see a hello world graphic:

Answer 5

You can easily check for the Imagick class in PHP.

if( class_exists("Imagick") )
{
    //Imagick is installed
}

Answer 6

In bash:

$ convert -version

or

$ /usr/local/bin/convert -version

No need to write any PHP file just to check.
