I think that user should do the conversion (in most cases it needs to be
reinterpolated).
I think that the current behavior is right for many reasons,

Hi,
When running r.relief (in GRASS7.1) on a integer DEM raster, the output
is an integer map. Is this intended behavior? Would it be possible to
have r.relief convert the layer to double precision / float
automatically if the DEM is of CELL type?

It appears to be hardcoded:
raster/r.relief/main.c
int out_type = CELL_TYPE;
...
but
In areas of low relief the integer DEMs have steps (you get alternating flat
and steep areas, with steep
areas along contours which you may be seeing in your shaded relief map), so
when you run
r.relief and you get a nice smooth map because the data were converted to float
using bilinear
Out of curiosity, what are those reasons? From a user perspective it
might not be that obvious (well, it wasn't for me at least). If the
current implementation is maintained, perhaps it would be useful to add
a note to the manual page?

Hi,
I was trying to render some maps automatically but I'm having problems with
setting the size of the image. I set size like this:
export GRASS_RENDER_HEIGHT=1350
export GRASS_RENDER_WIDTH=1500
But with cairo I get still the default size:
d.mon cairo
d.rast aspect
# map.png size is now
Thanks for the explanation, and yes, it does makes sense to leave it as
an option to the user.
Rgds,
Paulo
