I tried to send this request some days ago but it seems that it never
reached the list. I apologize if this request should reach you twice.
I am having some difficulties when trying to join several vector layers into
a raster file; GRASS will not draw vectors (polygons work fine) at the n
leftmost and/or n rightmost pixels of the image.
I use the d.area command to draw polygons and d.vect to draw lines. d.vect
seems to cut off lines that stretches beyond the edge of the image. Is this
a known problem or am I missing out on something?
An image that illustrate my point (roads and streams near the left edge is
cut off) might be found at:
It is generated with the following GRASS commands:
g.region n=4928226 s=4911624 e=612344 w=593807
d.area map=fields fillcolor=green linecolor=black
d.vect map=roads color=red
d.vect map=streams color=blue
I have also tried to use tcl/tk interface to generate the same image/map.
Here everything seems to work fine, see http://www3.norgit.no/apnee/tcl.png
Anyone know what I am experiencing here?
