ExactImage 0.6.5 (Default branch)
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. License: GNU General Public License (GPL) Changes:
The new image iterator and codegen was implemented for RGBA (RGB + Alpha) image data. The RAW camera file support was vastly improved by updating the 2 year old bundled dcraw copy as well as surrounding C++ glue code. Support for extracting the thumbnails of RAW files was implemented. The TIFF codec was improved to not to try to decode RAW images written as defective TIFF files. Image

OPTIMIZE2BW(1)							 ExactImage Manual						    OPTIMIZE2BW(1)

NAME

       optimize2bw - automatic thresholder of the ExactImage toolkit

SYNOPSIS

       optimize2bw [option...] {-i | --input} input-file  {-o | --output} output-file

       optimize2bw --help

DESCRIPTION

       ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
       depths natively, resulting in low memory and computational requirements.

       optimize2bw reads image files and performs 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 file, --input file
	   Read image from the specified file.

       -o file, --output file
	   Save output image to the specified file.

       -n, --denoise
	   Remove ("denoise") single bit pixel noise.

       -d n, --dpi n
	   Scale the image to the specified resolution.

       -h n, --high n
	   Set high normalization value.

       -l n, --low n
	   Set low normalization value.

       -r n, --radius n
	   Set "unsharp mask" radius. The default is 0.

       -s n, --scale n
	   Set output scale factor. The default is 1.0.

       -sd x, --standard-deviation x
	   Set standard deviation for Gaussian distribution. The default is 0.0.

       -t n, --threshold n
	   Set threshold value. The default is 0.

       --help
	   Display help text and exit.

EXAMPLES

	   $ optimize2bw -i logo.jpg -o logo.tif
	   Scale: 0
