NAME

       jpegjudge - guess jpeg picture quality

SYNOPSIS

       jpegjudge [ -V ]

       jpegjudge [ -b ] file ...

DESCRIPTION

       Jpegjudge  reads each argument and attempts to guess the quality with which it was saved. Currently, only a rough indicator is calculcated,
       ranging from 0 (lowest quality) to 1000 (highest quality), an extension to other formats would be straightforward, but isn't planned.

       It can read all pictures the IJG jpeg library can read, i.e. normal and progressive jpeg's.

   OPTIONS
       -b     Display only quality indicator, suppress other information (filenames).

       -h, --help
	      Display short summary of options.

       -V, --version
	      Display version number and exit.

BUGS

       It should be possible to judge pictures stored in non-lossy formats, too, since conversion to jpeg may influence the measurement.

       The quality indicator is non-linear, and could be much better.

       The algorithm to calculate the quality was made up in 10 minutes, after staring at various histograms.

ACKNOWLEDGEMENTS

       This program contains code from the IJG jpeg software.

NAME

       png2swf - Takes a number of png files and converts them to a swf movie, one picture per frame.

Synopsis
       png2swf [-X width] [-Y height] [-o file.swf] [-r rate] file1.png [file2.png...]

DESCRIPTION

       This  tools  converts  png  image  files into an SWF animation. It takes any number of input pictures, and converts them to SWF one-by-one,
       where every converted picture is a separate frame in the target SWF.

       The way the images are encoded in SWF is very similar to PNG (in that a zlib-based, lossless compression algorithm is used).

OPTIONS

       -r, --rate framerate
		  Set movie framerate (frames per second)

       -o, --output filename
		  Explicitly specify output file. (Otherwise, output will go to stdout / output.swf)

       -j, --jpeg quality
		  Generate a lossy jpeg bitmap inside the SWF, with a given quality (1-100)

       -z, --zlib zlib
		  Use Flash MX (SWF 6) Zlib encoding for the output. The resulting SWF will be
		  smaller, but not playable in Flash Plugins of Version 5 and below.

       -T, --flashversion
		  Set the flash version to generate

       -X, --pixel width
		  Force movie width to width (default: autodetect)

       -Y, --pixel height
		  Force movie height to height (default: autodetect)

       -v, --verbose level
		  Set verbose level (0=quiet, 1=default, 2=debug)

       -q, --quiet
		  Omit normal log messages, only log errors

       -C, --cgi
		  For use as CGI- prepend http header, write to stdout

       -V, --version
		  Print version information and exit

       -s, --scale percent
		  Scale image to percent% size.
