I updated 'bdftogd' script to get it works with new libgd (tested 2.0.33). Old version is still available as 'bdftogd.old'.
GD.pm is a perl5 interface to Thomas Boutell's gd library. Visit GD home page for more information.
Original information about how to use non-latin fonts and GD is here.
Download gd-koi8.tgz
Short instruction:
1. Be sure you have GD ver. 1.19 (get it from CPAN),
2. Unpack archive somewhere - tar xzvf gd-koi8.tgz
3. cd gd-koi8
4. run shell script: mkgd-cyr
5. Copy gdfont*.{c,h} into GD-1.19/libgd/ directory
6. remake GD module
7. test new fonts: ./fonttest |xv -
8. If everything is ok, make install and enjoy
Now you can make a pictures with Perl like this graph.
