fastresize is a small FastCGI daemon that resizes images on the fly. It has a very low memory footprint and uses almost no CPU time (except for the actual resizing that ImageMagick does, of course).
- ImageMagick
- libmagickwand
- libfcgi
fastresize was built to be used with nginx and makes use of some nginx-specific features like the X-Accel-Redirect. Altough it might be possible to get it to run with other webservers, it is untested (Early version have also been used with lighttpd).
Please see nginx-sample.conf for an example of how to configure your nginx to correctly pass requests to fastresize.
The syntax to launch fastresize is
fastresize [root] [thumbnail_root] [listen_addr] [user] [group] [num_workers]
- root
The directory assets should be served from. Don't forget the trailing slash.
- thumbnail_root
The directory thumbnails should be saved at. Don't forget the trailing slash.
- listen_addr
The socket address to listen on, for example 127.0.0.1:9000
- user
User name to run under
- group
Group name to run under
- num_workers
A number larger or equal to 1 that defines how many worker processes will be spawned. Usually, n+1 is a good choice (n = CPU cores).
