hello

How can I make a vector line thicker on display (d.vect ???)

In the display manager (D.M) just see all that U can achieve, includes thickenning vector lines too.

d.vect comes with a width= parameter to handle line width.

I wonder how hard it would be to implement line thickness based on an
attribute .... ?

just a thought.

I just added this feature to CVS, so could you please test if it's working for
you? There are two new options: wcol= and wscale=. Let's say you have a column
"channel_width" and its values are in meters.

d.vect map=streams width=2 wcol=channel_width wscale=0.05

means that line widths are 0.05 * channel_width and if this value is negative,
the default width (2) will be used. Please note that the line width column
should be either INTEGER or DOUBLE PRECISION type.

Huidae:

Wow! that was fast.

Looks like it works quite well. Thanks!

This could be done in a script. It is already implemented in
d.vect.thematic.

Yikes... after updating from CVS yesterday (after the line thickness patch) it
looks like vector polygons are not being drawn via d.vect:

getting segmentation faults when type=area !!

Any thoughts on that?

Sorry, I fixed it.
