Jpegtran

Jpegtran provides Ruby interface to the jpegtran tool. Some examples follow: (for details, see module documentation)

require "jpegtran"

Jpegtran.available?    # will return true (or false)

options = { :progressive => true, :optimize => true }
Jpegtran.optimize("foo.jpg", options)

# will run 'jpegtran -progressive -optimize -outfile foo.jpg foo.jpg'

It can be also run asynchronously by non-blocking way (with eventmachine) simply by giving block to #optimize. See documentation.

Unsupported Options

The -maxmemory N option isn't supported.
