GPIV_SMOOTH(1) General Commands Manual GPIV_SMOOTH(1)NAME
gpiv_smooth - Image smoothing program for PIV images.
SYNOPSIS
gpiv_smooth [-h | --help] [-p | --print] [-o N | --operation N] [-w N] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_smooth set each pixel value equal to the mean within a window and eventually subtracts, adds, mulriplies or divides the mean value.
The parameters read from the configuration resources (containing the key GPIV_IMGPROC) may be overruled by the command line options, as
explained below.
Options-h | --help
On-line help
-o N | --operation N
Set pixel equal to the mean of the window value (N0), subtract mean from from pixel (N1) add (N2), multiply (N3) or divide (N4)
-v | --version
Print version information on standard output, then exit successfully.
-w N window size (default: 15)
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.

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.

hi,
how does a program know whether some data are available from stdin?
I would like to make a program which could read its data from stdin
and _if_there_is_nothing_at_stdin_ from a file which name is given
as an argument. If there is nothing in stdin and no filename is given as
argument,... (2 Replies)
At the command line, If I type:
%dtpad filename &
It opens up a blank dtpad window, just as if I typed:

And no difference if I give it the pathname, such as:
%dtpad /here/there/filename &
No issues with passing a filename using vi, xedit, emacs, etc...

I posted this in the Advanced forum, thought I'd try it here as well...

Hi,
Program A: uses pipe()

* parent
-> char line;
-> read(fd, line, 100);
