[GRASS-user] grass-user Digest, Vol 152, Issue 4

[Micha Silver]

I'd like to point out that the combination of d.title and d.text is not 
working also on my system. I don't use the d.* modules much any more, 
but after seeing the OP's repeated posts, I decided to try.


I'm using Linux Mint, and here's what I did:


GRASS 7.4.0 (WGS84):~ > g.list rast
....
srtm_negev_3arc
....
GRASS 7.4.0 (WGS84):~ > g.region rast=srtm_negev_3arc

GRASS 7.4.0 (WGS84):~ > d.mon wx0                             # empty 
monitor appears
GRASS 7.4.0 (WGS84):~ > d.rast srtm_negev_3arc                 # map 
displays OK
  100%
# Now I try to add a title:

GRASS 7.4.0 (WGS84):~ > d.title -d map=srtm_negev_3arc color=red     # 
-d flag should display on wx0, but...
GRASS 7.4.0 (WGS84):~ > ERROR: Failed to run command 'd.text
input=/home/micha/GIS/grass/WGS84/PERMANENT/.tmp/TP480/11266.0
        at=50,50'. Details:

# Another try

GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc color=red size=10 | 
d.text align=cc
GRASS 7.4.0 (WGS84):~ >                     # No title appears


# How about text without d.title

GRASS 7.4.0 (WGS84):~ > d.text text="My Title" color=red at=5,5         
# Now text appears as expected!

GRASS 7.4.0 (WGS84):~ > echo "Second title" >> my_title.txt

GRASS 7.4.0 (WGS84):~ > d.text input=my_title.txt color=red at=25,25     
# Again text appears


# And d.title piped into a file also works:

GRASS 7.4.0 (WGS84):~ > d.title map=srtm_negev_3arc > my_title2.txt
GRASS 7.4.0 (WGS84):~ > cat my_title2.txt
.C black
.S 4.000000
LOCATION: WGS84
srtm_negev_3arc in PERMANENT

North:      32.00  South:      29.00
West:       33.00  East:       36.00
Resolution: n-s:    0.00  e-w:    0.00
GRASS 7.4.0 (WGS84):~ > d.text input=my_title2.txt color=red at=75,75    
# Text appears as expected


So maybe something is missing/not working in d.title | d.text combination ??

Regards, Micha
