Imagick::cropImage

Actually, the Imagick::setImagePage(0,0,0,0) is also handy with jpgs and pngs, if you plan to do any more changes on the cropped image that involves positioning and/or gravity (I created a script that does crop, face blur and watermarking in one go, and had a hell of a time determining why the blurs and the watermark text never showed up...).

When cropping gif-images (I had no problems with jpg and png images), the canvas is not removed. Please run the following command on the cropped gif, to remove the blank space:
$im->setImagePage(0, 0, 0, 0);

There is an easiest way to crop an image :
$picture = new Imagick('animated_gif.gif');
foreach($picture as $frame){
$frame->cropImage($width, $height, $x, $y);
}

If you're working with animated gif you might want to process this way (Probably not the best, but at least it works) :
$picture = new Imagick('animated_gif.gif');
//Crop first image
$picture->cropImage($width, $height, $x, $y);
//Crop every other image
while($picture->hasNextImage()){
$this->nextImage();
$this->cropImage($width, $height, $x, $y);
}
//display image
$picture->getImageBlob();
