Re: [udig-users] resolution lost on DRG

If you exported the map with the export enigine I think by default the
map is exported at screenshot resolution.
I think, but am not sure right now, that Jesse added also the
possibility to set the scale. If that is the case, by changing the
scale you should be able to gain higher resolution.
