[GRASSLIST:6479] Re: view raster image - d.mon causes crash

hey Iñigo,
changing SET DISPLAY improved things a little bit but did not solve my problem completely:
the bash shall “allows” new commands after executing d.mon but i am not able to see my raster data [see attachment].

so i guess there is something wrong with my data or with my entire approach:

    * scanned a map 1:25000 with 300 x 300 dpi so i got a tif image with
      3297 x 2399 pixel
    * created a xy location with NORTH EDGE 5085.88 EAST EADGE 6989.64
      and GRID RESOLUTION 2.12 so the number of rows and columns matches
      the image
    * imported the image, seemed to work as i can select the image as
      image to add to raster data using the GIS MANAGER d.m &

I really need to work with the data so if someone has a clue please help me.

regards
Axel

[can't]

Are you able to start a display monitor?

then d.rast?

If it remains blank, you might try setting the display region to where
your data is:

g.region rast=mapname

then d.redraw.

hey Hamish,
it did not occur to me that i had to set the region.
after doing so, i am now able to see the image.

thank you.

Would you mind to tell me what i can do with i.points, i.rectify ?

Cheers
