Moritz, could you try?

cvs up src/scripts/contrib/v.xfig

v.out.xfig v.in.xfig

I have no v.in.xfig in the v.xfig directory, but v.out.xfig works with awk
being in /usr/bin/awk.

I still have the problem that some of the files are not readable at all by xfig. If I see the pattern correctly it seems to be because v.out.xfig writes the coordinates in exponential format (7.67352e+11 4.57982e+11). Since xfig fails in those lines, I suppose that must be the problem.

I also have a file (with "normal" coordinates) where I get no error message and I can see the content of the file (circles made with v.bubble) in the preview window of xfig's file open window, but I don't see anything anymore once I open the file. I've tried zooming in and out to the max, but haven't found anything.

I created a test x-y location, 10x10, with three objects. The ascii vector file contains:

3.68509213 6.14740369

The file that results from v.out.xfig contains:

#FIG 3.2

293038 263758
290664 298578

i.e. the coordinates are much higher. I can see this drawing by zooming out very far, but is this normal behavior ?

MAP SCALE: 1

Here is the problem : v.out.xfig draw at a "1" scale, and does
not verify wheter at this scale the document will fit or not
on an A4 sheet of paper !

Use 100 in your test file and you will see the drawing

For the other files, use v.digit to change the scale.

BTW, I think that the "SCALE" of a vector map has nothing to do
with the print scale, which should be a parameter of v.out.xfig
