GPIV_GETBIT(1) General Commands Manual GPIV_GETBIT(1)
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. Param-
eters 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.
