[GRASS-user] grass 7 quick question: how to display map in text mode

Jarek_Jasiewicz1 · July 22, 2010, 8:17am

Hi
I need quick answer how can I show map in the text mode in grass7 (no d.mon)

It is because grass 7 wx gui has crashed after trying "save settings" in wxgui preferences and wen I try to work GRASS finish his work with following message:

I need any possibilities to see map results to track programing results on GRASS 7 but unfortuntely I cannot help with that error. It seems during "save settings" I blocked something but I cannot find what.

Below is the error message (grass 7 most recent svn, ubuntu 9.10 64 bits)

Thanks for answer
Jarek

Copy-pasting Glynn's answer (in the past) in a thread titled "grass70 and display monitor":

--%<---
You can approximate the pre-7.0 workflow using an image viewer which
automatically refreshes the display whenever the file changes. For X,
you can use the ximgview program, e.g.:

        export GRASS_PNGFILE=map.bmp
        d.erase
        ximgview &
        export GRASS_PNG_MAPPED=TRUE
        export GRASS_PNG_READ=TRUE
        # more d.* commands
-->%---

Hope this gets you there. Nikos

thanks for answer, but unfortunately no : (
ximgview still need wxpython it is solution only for old style display commands but not for corrupted wx

Could be an erroneous color preference setting that can not be read.
Color preferences must be stored as e.g. 255:255:255 and not
(255,255,255,255).
Open .grass7/wx and search for something like (255,255,255,255) with
values ranging between 0 and 255. If I am right and you find something
like this, please post the complete line of .grass7/wx to the ML,
delete the whole line and start grass7 again.

HTH,

Hmmm? I recently compiled grass_trunk (as described in the wiki at
<http://grass.osgeo.org/wiki/Compile_and_Install_Ubuntu>\) and the GUI launches
fine (under Kubuntu 64-bit). I have to note however that I rarely "work" with
the GUI, so I only assume it works fine.

I have the following in ~/.bash_profile:
--%<---
# grass
export GISBASE=/usr/local/grass-6.4.0svn
export GRASS_GNUPLOT='gnuplot -persist'
export GRASS_WIDTH=640
export GRASS_HEIGHT=480
export GRASS_HTML_BROWSER=firefox
export GRASS_PAGER=cat
export GRASS_WISH=wish
export GRASS_PYTHON=python
export GRASS_MESSAGE_FORMAT=silent
export GRASS_TRUECOLOR=TRUE
export GRASS_TRANSPARENT=TRUE
export GRASS_PNG_AUTO_WRITE=TRUE
--->%--

(Actually I have configured my system as described in the following wiki-page
<http://grass.osgeo.org/wiki/Working_with_GRASS_without_starting_it_explicitly>\)

So, within from a grass7 session, any "d.rast" command (or other drawing)
creates a file map.png (under the current working directory each time). And I
can view it with any image viewer.

GRASS 7.0.svn (spearfish60):~ > export GRASS_PNGFILE=map.bmp

here you have to draw something, i.e. "d.rast SomeRasterMap"

GRASS 7.0.svn (spearfish60):~ > d.erase
GRASS 7.0.svn (spearfish60):~ > ximgview &
[1] 29591

I think "ximgview &" was suggested as a lightweight and quick viewer, that
stays open like the (old-)x.mons (...good-bye Xmons ). But this is I think
irrelevant with this corruption, I think.

Do you launch grass in text-mode? i.e. "grass70 -text GRASSDB/LOCATION/Mapset"
?

Apologies, I didn't see the expert comment before writing my post. Hopefully
the above explains the corruption problem.

there is nothing like this, but removing .grass7/wx has made wx working. I will create default wx file and gui crashes again. Diff says that there are no differences between old and new wx file so I think that something in default settings create crash.
thanks and cheers

Nope, there are two programs, ximgview and wximgview.

Or just use your favourite image viewer for it. When ssh'ing to
the big server I use qiv for this. All you need is something that
updates the view when the image changes. (when out in the field
with terrible internet connection I've even used putty + a web
server to ssh commands + refresh to view the map.png file before).

`qiv --watch map.png`

this bug is related to wxNviz, I will fix it ASAP.
