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.
