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.
