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.
