Dane, Many thanks for replying :) I'll have to study Cairo library for generating legends on maps.
Meanwhile I often wondered that why haven't you responded to two of my former mails which are as follows: 1. https://lists.berlios.de/pipermail/mapnik-users/2010-January/002821.html 2. https://lists.berlios.de/pipermail/mapnik-users/2010-January/002843.html Answer to Legends query is clear to me now, but there were some other queries too in these mails... If you find that the questions I ask are too dumb to get answered, please let me know, so that I can improve on the quality of questions. -- Regards, Anisha Kaul On Monday 01 February 2010 12:42:40 Dane Springmeyer wrote: > Hi Anisha, > > That page simply lists ideas and wishes.
