gpiv_getbit - Image processing program for PIV images.


gpiv_getbit [-b N] [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout


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.


-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.
