Hi all,

I would like to announce that a new wxGUI feature - Map Swipe - is now
available in grass 7. This tool enables to interactively compare two
raster maps of the same area by revealing different parts of the
raster maps. To understand more please look at the wiki page [1] where
you can find an example of usage and video tutorial. To run Map Swipe
go to menu File -> Map Swipe.

The tool is really wonderful, also to compare resampled data (added to
http://grasswiki.osgeo.org/wiki/Interpolation#Comparing_original_and_interpolated_data
).

It would be nice to have an icon for this, perhaps Robert would create
one for us?

thanks
Markus

Hi!

I observe(d) that another wx monitor wont play nice (or at all) if
g.gui.mapswipe is running. Is that by design or undesired behaviour?

Thanks, N

Hi, I think that this was already discussed, but to answer your question:

It is a known bug. Map Display in the main wxGUI and all other
displays such as mapswipe in the main GUI does not work with d.mon. It
is probably because some GRASS environmental (file-managed) variables
clash.

I'm not sure if some specific ticked exists but there is a page about
rendering in general:
