Hi,
several days ago I asked something about text windows and the
possibility of implementing subscript letters in Dia.
I wonder if enhanced postscript functionality is not implemented at the
moment, like it is e.g. in gnuplot? In gnuplot, I can type V_{in}, where
the {in} is being converted into subscript letters when the plot is
exported in enhanced postscript mode. I tried this with Dia, but the
subscript text appears as typed before in the eps file.
I'm not an postscript expert, so of course I don't know anything about
implementing this functionality and the possible drawbacks...
Until now I have created some simple electrical circuit diagrams with
Dia and I really like the easy and intuitive handling. The program would
be nearly perfect if the subscript funktionality would be implemented.
The same wish has been stated several times for TeX and LaTeX. Apart
from the practicalities of having a number of different interpreters the
main problem is finding out the size of the result for determining boxes
etc. One way to do that would be to make call-outs to external programs
that can create appropriate bitmaps, in which case I would have no
problem letting people define their own TeX, EPS, SVG or whatever
languages.
We are hoping to move towards a more advanced text input system that
uses real GtkEntry widgets, but there's a ways to go there yet. With
those, we could conceivably do whatever markup GTK allows for its text
entry.
