Problem

• Images are too large because they are not optimized
• Users & your bandwidth is wasted for useless metadata
• local image optimization requires tons of programs / libaries / knowledge

Solution

• LOSSLESS size reduction (10-97% size reduction) in the cloud
• optmizes all images(jpg+png+[gif]) from a given folder

Install

install ruby + rubygems + curl
sudo gem install grosser-smusher --source http://gems.github.com/

Usage

Optimize a single image or a whole folder in the cloud.

converting gif-s to png-s:

• called with a folder gif-s will not be converted
• called on a singe .gif, it will be converted if it is optimizeable

Usage:

smusher /apps/x/public/images [options]
smusher /apps/x/public/images/x.png [options]

Options are:

-q, --quiet                      no output
-c, --convert-gifs               convert all .gif`s in the given folder

Protection

Any image that returns a failure code, is larger than before,
or is empty will not be saved.

Example

smusher /apps/ts/public/images
  smushing /apps/rs/public/images/social/facebook_icon.png
  2887 -> 132                              = 4%

  smushing /apps/rs/public/images/social/myspace_icon.png
  3136 -> 282                              = 8%

  smushing /apps/rs/public/images/dvd/dvd_1.png
  5045 -> 4                                = 0%
  reverted!
  ...

TODO

• only optimize 'new' images -> save time when doing on each deploy
• use ruby library rather than curl
• support smusher images/*.png ?
