Hi,

Dear Anna,

Problem with g.gui.animate solved! It’s a long story, but I had several
versions of libpng on my system, and the most recent one (libpng16) was
loading into GRASS along with the others and messing things up. I moved
the library where it could not be found, recompiled GRASS, and
everything worked!

Thanks for your assistance. Your email said g.gui.animate worked on your linux
system and that made me start to suspect something on my system outside
of GRASS could be at fault.

Glad to hear that! If you have other issues, just ask.

Anna

Thanks again.

Hi,

are you using wxGUI (Layer manager + map display) or d.mon wx0? If you are
using d.mon, it could cause this strange behavior. If that’s not your case,
please try again with updated version of grass, I added some warning if
rendering fails. So have a look in the terminal if there is some warning.
You can also set debug mode before launching animation tool:
g.gisenv set=WX_DEBUG=5
g.gisenv set=DEBUG=5

and send me the output.

Hopefully some of these suggestions will be helpful.

Dear Anna,

Thanks for your reply. I set the “computational region” to one of my
rasters but still could not get the actual rasters to display on the
screen.

The filename of the first raster is present at the upper left corner, but
no actual
picture appears. In addition, the filename does NOT change as the
slider moves across.

In addition, if I check the “Show raster legend” box in the “Add new
animation” window, , I receive the following error message, which may
help:

Thanks for your help.

I wasn’t sure if I should reply to the list, so I sent this directly to
you.
