Do you suggest to use this flag by default?
Yes.
please try out r60251 (trunk).
Doesn't work for me. I still get values such as;
{{{
nsres: 9.9953005
ewres: 9.99522706
}}}
while working with the 10m resolution elevation data from the NC dataset.
I've tried playing with the different constrain settings in the wxGUI
MapDisplay (Constrain display resolution to computational settings and
Align region extent based on display size), but no combination of the
two seemed to do the trick.
Does the GUI internally redefine the region for display and then applies
that region in that call to g.region ?

Does the GUI internally redefine the region for display and then applies that region in that call to g.region ? This reminds me of my question posted in grass-dev: On Wed, Apr 16, 2014 at 6:09 PM, Markus Neteler nete...@osgeo.org wrote: Hi, when trying to render a large raster map with d.rast in the command line version (d.mon wx0), then it tries to use the current region which leads to a cairo memory error. It seems that the wxGUI is initializing the display in a more reasonable way to downsample the map to be rendered on the fly since it makes no sense to render it at original resolution. This magic is yet missing in d.mon. Where is that calculated in wxGUI to get an idea about the calculation of map display window size versus raster map size/resolution? Maybe related, maybe not. In any case a resolution/region issue. -- Ticket URL: https://trac.osgeo.org/grass/ticket/2277#comment:20 GRASS GIS http://grass.osgeo.org ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev

I don't mean to interact with region resolutions, only with boundaries. If I refer to gui/wxpython/mapdisp/mapwindow.py, it would be a kind of mix between functions Zoom(self, begin, end, zoomtype) and DisplayToWind(self). The latter is nice except if you need to define a region whose dimensions don't fit with the map display frame ratio... My knowledge of python is too poor to propose any concrete coding, but I guess it should not be that tricky to implement. Does anyone else think it's a good idea that wxgui provides an on-the-fly method for region setting ? -- Ticket URL: http://trac.osgeo.org/grass/ticket/2277 GRASS GIS http://grass.osgeo.org ___ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
