unable to save display of d.rast.num

[cmbarton]

I just learned that I can no longer save a display of cell number using d.rast.num in GRASS 7. I know this worked for a talk I gave earlier this year. Now it does not.

I get a bogus error about the region being too large. But the region it gives is NOT the display region, the computational region (matches the display region in this case), or even the size of the raster map.

Here is an example using the elevation raster from the sc_08 data set. I've reduced the computational region and display region (and have them matched) in order to display cell numbers. And the display is constrained to the computational region (it must be to display cell numbers). So here is what happens. Note the size of the region and the error.

Command 'd.rast.num map=movwin_elev_max@spatialtech2012'
failed

Your current region setting may be too large. Cells

Currently d.rast.num in GRASS 7 does not output anything in wx0:
