Imagick::getImageResolution

For me getImageResolution() always returns X and Y resolution in pixels per centimeter, no matter if I set it with setImageUnits() or not.So an easy way to convert the result from pixels per centimeter to pixels per inch is to do this:<?php$resource = new Imagick($path);$imageResolution = $resource->getImageResolution();if (!empty($imageResolution['y'])) { $imageResolution['y'] =                             round($imageResolution['y'] * 2.54, 2);}if (!empty($imageResolution['x'])) {$imageResolution['x'] =                             round($imageResolution['x'] * 2.54, 2);}?>

Please note that this method seems to return the image density, or DPI, not it's output resolution. If you want the output resolution, please refer to Imagick::getImageGeometry: http://www.php.net/manual/en/imagick.getimagegeometry.phpSee http://www.imagemagick.org/Usage/basics/#density for more infomation on the difference.

//location of image: c:/htdocs/rose.jpg$path="c:/htdocs/";$image=new Imagick($path."rose.jpg");$array=$image->getImageResolution();print_r($array);result:Array(    [x]=>75    [y]=>75)

As of the following versions, the results of this function returns the x and y resolution as floats.desktop:~$ convert --versionVersion: ImageMagick 6.6.9-1 2011-04-14 Q8 http://www.imagemagick.orgCopyright: Copyright (C) 1999-2011 ImageMagick Studio LLCFeatures: OpenMP OpenCL desktop:~$ pecl listInstalled packages, channel pecl.php.net:==========================Package Version Stateimagick 3.0.1   stabledesktop:~$ php --versionPHP 5.3.5 (cli) (built: Mar  1 2011 12:57:53) Copyright (c) 1997-2010 The PHP GroupZend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies    with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans
