We have imported scanned photos and everything seems fine
except that when we display them there seems only to be 8 shades of
grey while we have 16 categories. We intend to rectify these and
map on them with digit. It would be very helpful if we could get all
shades shown on the display. Any suggestions?
You'll probably get this answer from more people, but try d.colormode
float, then d.erase and display your map again. This should give you more
than 8 grey shades.
