NAME
gpiv_getbit - Image processing program for PIV images.
SYNOPSIS
gpiv_getbit [-b N] [-h | --help] [-p | --print] [-v | --version]
[filename] < stdin > stdout
DESCRIPTION
gpiv_getbit get the N least significant bits and moves them to most the
significant bits. This results that a weak image signal (pixels of low
value) is amplified while the high signal within the image will be
removed.
The parameters read from the configuration resources (containing the
key GPIV_IMGPROC) may be overruled by the command line options, as
explained below.
Options
-b N Defines the bit number [0, .., 7]. Signal from 0 to N will be
shifted.
-h | --help
On-line help
-v | --version
Print version information on standard output, then exit
successfully.
filename
Input image filename. Overrides stdin and stdout with the full
filename of the image. Output will be written to filename.png.
Parameters are stored in filename.par and may be used for future
use by including them in ./gpivrc. If stdin and stdout are used,
the input is expected to be a PNG formatted image.
