Right now I use Image::Magick to create thumbnails for my website. However, since it would look nicer, I want a square thumbnail. Since the original images are not square, I first resize the image and then I crop it. But it always crops from the lower left. I would like it to crop from the center of the image. If I did this on the command line I would use the gravity option, i.e.: 

mogrify  crop 200x200+0+0 -gravity center file.jpg

However, looking at the docs it seems that Crop does not have the gravity option. Any clues? Thanks.

This is what I am currently doing:

my $image = Image::Magick->new;
$image->Read($file);

my ($width, $height) = $image->Get('width', 'height');

if($width < $height) {
  my $nh = $size*$height/$width;
  $image->Resize(width => $size, height => $nh);
} else {
  my $nw = $size*$width/$height;
  $image->Resize(width => $nw, height => $size);
}

$image->Crop(width => $size, height => $size);

Edit: I found what I needed. To set the gravity you do this: 

$image->Set(Gravity => 'Center');

If you add that before the Crop the above function works like I desired!
