exporting schematic for latex and changing paper size in geda

    Hi,

    I am currently experimenting with geda and ngspice to simulate basic
    circuits (for a Circuits Analyses course). I drew a basic circuit in
    geda and exported it as netlist and got:
    #######################################################
    $> gnetlist -v -g spice-sdb sch_1.sch -o sch_1.net
    ... (followed by lots of output) ...
    $> cat sch_1.net
    * gnetlist -v -g spice-sdb -o sch_1.net sch_1.sch
    *********************************************************
    * Spice file generated by gnetlist *
    * spice-sdb version 10.9.2004 by SDB -- *
    * provides advanced spice netlisting capability. *
    * Documentation at http://www.brorson.com/gEDA/SPICE/ *
    *********************************************************
    V1 2 3 10V
    R2 1 3 50K
    R1 2 1 100K
    ..END
    #######################################################


    I was wondering:
    1. How can I specify within geda which nodes I want monitored during a
    simulation? Or do I specify them on ngspice command line, or in the
    output .net file?
    2. How do I export the schematic so that I can include it in a LaTeX
    file (as PS file perhaps)? I tried exporting it as PNG but I get the
    whole big 'sheet' with my tiny circuit in the middle.
    3. How do I change the size of the 'sheet' or paper so that it is just
    big enough to accomodate my little circuits?

    thanks,
    ->HS

    First of all, you would get much better answers on the geda-user mailing
    list. http://geda.seul.org/mailinglist/index.html

    Print doesn't actually print anything, but produces postscript. There is
    an option to print what is currently displayed. I just zoom in until I
    just have what I want, and then use the print dialog. There is also an
    option for extents with margins and extents without margins. These methods
    have worked for me in the past to get schematics into LaTeX.
