If you don't want to provide a notation for the chess diagram,
you can specify the option ``-n'' while calling Fen2eps.
The board is output without notation letters and digits then.
You might want to display a board from Blacks perspective. In this case, use
the option ``-r'' which creates a diagram that is drawn reverse.
Exporting several FEN strings with the same settings is a
tedious task. Fen2eps can help if you prepare a file, let's
name it `many.fen', that contains all the chess positions you
want to convert. By specifying the
``-p'' option you give Fen2eps a file prefix it can use
for generating single EPS diagrams automatically. You can say
fen2eps -p diag/dg < many.fen
for example. What you get is one EPS file for each FEN string in `many.fen'.
These EPS files are created in the directory `diag' and have the prefix
`dg' followed by a unique number.
If the
``-p'' option is given, Fen2eps does NOT write to
`stdout' but to the created files directly. So redirecting the
output by appending a
> isempty.eps
to the program call does not have any effect (except that you get an
empty file named `isempty.eps'...).
Of course, you can mix all these options and after the call
fen2eps -n -r -p diag/dg -f fed/lucena.fed < many.fen
(let's assume the file `many.fen' contains 7 FEN strings...) you
can find the files `dg1.eps' to `dg7.eps' in the
directory `diag'. All boards are displayed reverse, without notation
and use the font ``Chess Lucena''.
