spiralpack
(de-)compresses spiral images from 345mm mar research Imaging Plate Detector
Systems. The used algorithm (author: Dr. J.P. Abrahams, Cambridge, UK) is more
efficient and faster than standard UNIX compression or gzip and can easily
be implemented in other programs. The default file name extension of packed
and unpacked spirals are spkXXXX and sXXXX, respectively, where XXXX denotes
the four-digit image size (1200, 1600, 1800, 2000, 2300, 2400, 3000 or 3450).
Lists the selected
files (directories) only, no output.
-f, --force
Forces image output, even
if a file with the same name already exists. The default is to skip output.
-d, --delete
Deletes input image after successful conversion. The default is
to keep the input file.
-r, --recursive
If the file argument (see below) is
a directory, all images in this directory and its subdirectories will be
converted. This is a very fast way of converting large numbers of images
scattered in many directories.
-v, --verbose
Writes more information to stdout.
-o DIRECTORY
Output images will go into directory DIRECTORY. By default,
they will be in the same directory as the input images.
