Fujifilm FinePix REAL 3D universal decoder for Linux and Mac

[sanmai]

This script extracts the left and right image from any .MPO file, crops them to match the embedded parallax value, then makes an anaglyph image, stereopair (JPS, Stereo JPEG analogue), and also an animated GIF for your viewing pleasure.

Prequisites: bash, ExifTool, ImageMagick, and bc.

See example output at the bottom.
