DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike ImageMagick,
it allows operation in several color spaces and bit depths natively,
resulting in much lower memory and computational requirements. Some
optimized algorithms operate in 1/20 of the time ImageMagick requires,
and displaying large images can be as fast as 1/10 of the time the
"display" program takes.
optmize2bw reads shaded, color or gray image files and does perform
automatic thresholding and optional scaling on the data. It is useful
for long term archiving of documents that have to be stored in sub-byte
black and white data to reduce storage requirements.
OPTIONS
-i, --input FILE

-l, --low VALUE
Low normalization value.
-r, --radius RADIUS
"unsharp mask" radius.
-s, --scale SCALE
Scale output by factor.
-sd, --standard-deviation DEVIATION
Standard deviation for Gaussian distribution.
-t, --threshold VALUE
Threshold value.
