.SH SYNOPSIS
.B k8100grab
[\-f #] [\-d #] [\-v #] [\-s] [\-p] [\-w filename]
.SH DESCRIPTION
This version of \fBk8100grab\fP lets you view or save frames coming from the
Velleman K8100 videograbber. See http://www.velleman.be about the hardware.
Viewing is done by the svgalib(7) library functions, thus you should run this tool from a console, not from the X Window system. 
.SS OPTIONS
.TP
.I "\-f #"
Grab number of frames. The default is 10 frames and 1 frame if 1 outputfile 
is specified.
.TP
.I "\-d #"
Delay number milliseconds (1/1000 sec) between a frame. The default is 80 milliseconds, which should be the minimum. Long delayes can be specified as well, e.g. 10 seconds (-d 10000) or 1 hour (-d 3600000).
.TP
.I "\-s"
Use small frames with pixelsize 256x256 instead of the normal 512x512 size.
This format generates thus four times less diskspace and is much faster.
.TP
.I "\-v 0|1|2"
Set the display resolution to 320x240 when the argument is 0, 640x480 when 1 and default to 800x600 when 2 (or more). 
.TP
.I "\-w filename"
Write the output to filename instead of just showing with svgalib(7).
When you specify %02d,  %04d, %06d in your filename you will be able to record 100 frames, 1000 frames of 1000000 frames respectively in seperate filenames. e.g. image00.gray, image01.gray, image02.gray, image03.gray,... when you specified image%02d.gray as the filename.
.TP
.I "\-p"
Use this option to write your files in the PGM graphic format (Portable Grayscale Map). File extension should be .pgm or .pnm for convenience.
