Re: gEDA-user: graphics and sub and super scripts

[John Luciani <jluciani@xxxxxxxxx>]

You could place two text items --- one for the variable and one for
the subscript such as

v 20050313 1
A 510 400 200 224 272 3 0 0 0 -1 -1
{
T 510 400 5 10 0 1 0 0 1
device=none
T 1510 400 5 10 0 1 0 0 1
graphical=1
T 510 400 5 10 0 1 0 0 1
description=Symbols of mesh current.
}
T 446 350 8 10 1 1 0 0 1
refdes=i
T 510 320 8 6 1 1 0 0 1
sub=?
L 360 270 380 200 3 0 0 0 -1 -1
L 360 270 430 260 3 0 0 0 -1 -1

Since you are using LaTeX you may want to check out 
http://www.ece.uwaterloo.ca/~aplevich/Circuit_macros

Creating a schematic with the macros is quite a bit more difficult
than using gschem but it does produce some great looking graphics.
