Update to gen_ladder.pl tool

Hi! I've finally taken some time to re-write the gen_ladder tool in order to avoid the stupid 'bent arrow' problem that was caused by using 'dot'. I'm now drawing bitmap images directly from Perl using 'GD', rendering PNG images. Support for printing a title and automati scaling of the font size has been added. However, this new version doesn't yet support the bi-directional arrows and dashed lines. Patches are welcome ;) I tried to use GD::SVG at some earlier version, and it seemed to work too, i.e. we will have an easy path to still generate vector graphics, if required. There are also way more *.lad files in the repository now for various protocol transaction, including supplementary services, roaming calls, etc. Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
