Lets say you want to reduce the resolution of uploaded images for the web.





The following will load a image at whatever resolution and resample it down to 72 dpi and save as a different file.





The dpi for setImageResolution() and resampleImage() should be whatever dpi your resampling too.





<?php


$image = new Imagick();


$image->readImage('image.jpg');


$image->setImageResolution(72,72);


$image->resampleImage(72,72,imagick::FILTER_UNDEFINED,0);


$image->writeImage('image72.jpg');


?>
