keys:
-x|cross: double image for cross-correlation (default: single image
for auto-correlation)
-c|cols ncolumns: the number of columns in the frame (default 1280)
--combine combinates two separate image frames to a single one for
cross-correlation. Also look at --suf_a/b and --suf_num
-d|depth depth: color depth (default 8)
-h|help: on-line help
-hdf: converts to (or from) hdf format (extension .hdf)
-i: inverse conversion; from raw 8-bit data to image format
--suf_a with --combine: suffix of first image (default: _a)
--suf_b with --combine: suffix of second image (default: _b)
--suf_num N with --combine: subsequent numbered images of which the
first one with number N and the second N+1. The converted
image will be named to file_base_name + N
-n: no execute, only print processes
-noclean: do not remove existing image
-r|rows rows: the number of rows in the frame of a SINGLE image
(default 1024)
-p: prints process to stdout
-t: image type or format (default bmp)
