Calibration images
Compiled python sources
addblur() function

Added the addblur() function shell, no function as of yet.
mod_encode_decode_1.2 release

Updated mod_encode_decode to 1.2.

See changelog for details.
mod_imgtools update

Still no release, added the addblur() function and tweaked outputs to
not print so much so it's easier to work with in main code.
