xastir-capture is a freepascal program (you open it in lazarus if you wish, its fpc based like lazarus) the program is just a simple program for using ImageMagick to capture a png file in the directory you are standing...) the purpose of this is to build a screen-shot of what you are seeing "live" so you can make documentation later..
It is not limit to xastir.. nb read README b4 you start.
use xwininfo to find out your xastir session, and use the program as this:
xastir-grabber "session name" "delay in ms"
you only uses space between the options... nb this dose not replace the screen shot option in xastir.. it just a different way of taking screen-shot, and it dose`t effect xastir. how ever be sure to have xastir open in the window.. an look at the log output... (if it is not counting but giving error you are not getting any images.)
new in version .03 you only need to write host name.. as long as you use one session in the xscreen you are using. if you use more then one use version 0.2
