PROGRAM:
NAME
jpeginfo - prints information and tests integrity of JPEG/JFIF files.
SYNOPSIS
jpeginfo [ options ] [ filenames ]
DESCRIPTION
jpeginfo is used to generate informative listings of jpeg files, and also to check jpeg
files for errors. Program also supports automatic deletion of broken jpegs.
OPTIONS
Options may be either the traditional POSIX one letter options, or the GNU style long
options. POSIX style options start with a single ``-'', while GNU long options start with
``--''.
Options offered by jpeginfo are the following:
-c, --check
Check files also for errors. (default is just to read the headers).
-C, --comments
Display file comments (from COM markers).
-d, --delete
Delete files that have errors. (default is not to delete any files).
-f<filename>, --file<filename>
Read filenames to process from given file. To use standard input (stdin) use '-' as
a filename. This is alternative to default where filenames are given as parameters
to the program.
-h, --help
Display short usage information and exits.
-5, --md5
Calculates MD5 checksum for each file.
-i, --info
Displays even more information about each picture. Prints image coding
(Huffman/Arithmetic), density (in dpi/dpc), and whether CCIR601 sampling was used or
not.
-l, --lsstyle
Uses alternate listing format (ls -l style).
-v, --verbose
Enables verbose mode (positively chatty).
--version
Displays program version.
-q, --quiet
Quiet mode, output just the jpeg infos.
-m<mode>, --mode=<mode>
Sets the delete mode, meaningful only when used with -d flag. Mode can be one of
the following:
all files containing any type of errors/warnings, not necessarily preventing the
decoding. (default)
erronly
only files with serious errors (ie. cannot be decoded at all).
