./configure CC=arm-linux-gnueabi-gcc --host=arm-linux-gnueabi
Usage: jbig2dec [options] <file.jbig2>
or jbig2dec [options] <global_stream> <page_stream>
When invoked with a single file, it attempts to parse it as
a normal jbig2 file. Invoked with two files, it treats the
first as the global segments, and the second as the segment
stream for a particular page. This is useful for examining
embedded streams.
available options:
-h --help this usage summary
-q --quiet suppress diagnostic output
-v --verbose set the verbosity level
-d --dump print the structure of the jbig2 file
rather than explicitly decoding
--version program name and version information
--hash print a hash of the decoded document
-e --embedded expect embedded bit stream without file header
-o <file> send decoded output to <file>
Defaults to the the input with a different
extension. Pass '-' for stdout.
-t <type> force a particular output file format
supported options are 'png' and 'pbm'
