jbig2dec 1 "2020 March 11" "Version 0.19" "jbig2dec Manual"
NAME
jbig2dec - File format converter specialized in JBIG2 decoding
SYNOPSIS
jbig2dec [ options ] file.jbig2

jbig2dec [ options ] global-stream page-stream

DESCRIPTION
The jbig2dec command converts JBIG2 files to png or pbm files. When passed a single file argument it is interpreted as a JBIG2 file stream, with either sequential or random-access organization. When passed two stream arguments, they are interpreted as the global and page-specific portions of an embedded organization, as used in PDF. If a particular page references no global segment stream, /dev/null can be passed for the global-stream argument to request the embedded parser.
OPTIONS
The options are as follows:

-e ", " --embedded Expect embedded bit stream without file header.

-o " file" ", --output" " file" Store the decoded output in file . Defaults to the input with a different extension. Set to - for standard output.

-t " type" ", --format" " type" Force a particular output file format. Supported are png and pbm.

-d ", " --dump Print the structure of the JBIG2 file rather than explicitly decoding it.

-m ", " --hash Print a hash of the decoded document.

-q ", " --quiet Suppress warnings and other diagnostic output.

-v ", " --verbose Report additional information about the decoding process. Pass just -v for information about the file as it's being decoded. This is the same as --verbose=2. Pass --verbose=3 or higher for debugging information.

-V ", " --version Show program version information.

-h ", " --help Show usage summary.
