Smart Image Cropping and Resizing

By tom611 on 24 Nov 2006 at 20:22 UTC

Does anyone know if there are any options for smart resizing/cropping of images? For example, I want to dynamically resize a user profile picture to a fixed HxW (easy) but also crop it based on the actual image...ideally around the main element in the picture...like someone's head. They seem to be doing this on yelp.com, but I cannot find any script that actually examines the content of the image before cropping. Thanks in advance.

have a look at the image_enhanced_scaling module in the repo. I breezed by it a few days ago so I can't be sure that it will do what you are asking.

I use the gallery 2 software package and module. Gallery2 happens to do this and create square thumbnails as well as a few other things, then with some php trickery use those photos.

Yea I saw the image scaling

Yea I saw the image scaling module...looks promising for resizing, but I am looking for smart cropping options as well. Are you saying that Gallery2 can set the crop position around what's actually in the picture?

gallery allows me/users to place the crop where ever I/the user wants them, rather then cropping the entire image. it doesnt autoguess at what the focus of the image is however.

That is a step in the right

That is a step in the right direction. Was this difficult to get working with drupal?

Does anyone else know of a cropping solution that guesses at the crop position based on the subject of the picture?

nope using G2 with the G2image addon and the gallery 2 module from the drupal.org was easy.

the Gallery2 project at gallery.menalto.com uses drupal as its cms. if you havent taken a look. They managed a nice implementation into drupal 4. I'd imagine they will also move to 5.0 once its released and stable.

Smart Crop module

The Smart Crop module does an awesome job of this. It's based on entropy so it doesn't do face detection but it does do a great job of finding what's interesting about an image and keeping as much of that as possible. It's also written by a really bang-up guy who's really active in the security team so you know it's a pretty solid thing.
