Glynn,
I've made a lot of progress getting your TclTk replacement for
Xganim into the GUI. However, I haven't been able to make it
animate anything. I finally tracked this down to the line...
catch {exec r.out.ppm input=$name output=- 2>@stderr | pnmscale
$vscale >$tmpfile 2>@stderr}
This requires a program pnmscale. I don't have pnmscale. Does it
comes with GRASS and I somehow don't have it or is it a 3rd party
program?
Michael, you have to install it
http://netpbm.sourceforge.net/doc/index.html
Also I found in the pnmscale manual:
pnmscale was obsoleted by pamscale, introduced with Netpbm 10.20
(January 2004)
I have it on RedHat linux box but I don't have it on Mac or Ubuntu so
apparently you have to install it yourself.
