[mapserver-dev] Canvas support for MapServer

[Jan Hartmann]

Hi folks,

A few weeks ago I suggested in a thread about PDF support that Mapserver 
could perhaps be made to support the new "Canvas" tag. There were no 
reactions to this, so I don't know if this suggestion is 
viable/advisable/practicable, or just downright stupid. Can anyone 
comment?
