open-source smart on-demand image cropping, resizing and filters.

thumbor is a smart imaging service. It enables on-demand crop, resizing and flipping of images.

It also features a VERY smart detection of important points in the image for better cropping and resizing, using state-of-the-art face and feature detection algorithms (more on that in Detection Algorithms).

Using thumbor is very easy (after it is running). All you have to do is access it using an URL for an image, like this:

http://<thumbor-server>/300x200/smart/thumbor.readthedocs.io/en/latest/_images/logo-thumbor.png

That URL will show an image of the thumbor logo in 300x200 using smart crop.

There are several other options to the image URL configuration. You can check them in the Usage page.

For more information check thumbor's documentation.

Decide which installation option you want to use.

pip install thumbor

sudo add-apt-repository ppa:thumbor/ppa

sudo aptitude install thumbor
