If you get an error or warning (when using strict settings for PHP), telling you, that this function should not be used anymore try getImageLength() instead ...

Practical use to get the dimensions of the image:





<?php


$image = new Imagick($image_src);


$d = $image->getImageGeometry();


$w = $d['width'];


$h = $d['height'];


?>

If you're planning to stream imagick images via http, pay attention that this function may return the uncompressed image size, so it's not directly suitable for setting the content-length http header.

Try Imagick::getSize, Imagick::getImageWidth, or Imagick::getImageHeight if you are looking to get dimensions in pixels (rows, columns) of the current image.
