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 organzation, 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:
- -o file
- Store the decoded output in file. Defaults to the
input with a different extension. Set to - for standard
output.
- -t type
- Force a particular output file format. Supported are
png and pbm.
- -d or --dump
- Print the structure of the JBIG2 file rather than
explicitly decoding it.
- --hash
- Print a hash of the decoded document.
- -q or --quiet
- Suppress warnings and other diagnostic output.
- -v or --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.
- --version
- Show program version information.
- -h or --help
- Show usage summary.
