Hi, I use 'webcam' for mine, and in the config file (as you can see below) the width and height of the target image can be specified. However, that's not what you asked for.
convert -resize widthxheight should do it, but you could also set the jpeg quality lower to make a smaller file. My webcam shows 320x240, and images are typically 20Kb in size. http://homepages.paradise.net.nz/blighty/webcam/ There's also a lot of examples and help on 'convert' at http://www.imagemagick.org/ HTH Andy -- (Part of .webcamrc shown below) [grab] device = /dev/video0 text = %Y-%m-%d %H:%M:%S %Z #infofile = filename width = 320 height = 240 delay = 3 input = composite0 norm = ntsc rotate = 0 top = 0 left = 0 bottom = -1 right = -1 quality = 75 trigger = 0 once = 1 archive = webcam_archive/webcam%Y%m%d%H%M%S On Sat, 25 Sep 2004 17:32, Steve Holdoway wrote: > Hi folks.
