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.
