[mapserver-users] Export SVG

[Maria Neywell]

Hi,



Sorry, I don’t think you are getting it right. I’m going to try to explain
it differently.



The aliasing in my svg file rendered by mapserver is independent of the
viewer. Mapserver automatically simplifies geometries during the svg
generation, so the geometries rendered in a SVG file don’t match with the
ones in my original map.



See enclosed a picture to explain my problem. Iit will help you to
understand and to compare before and after SVG generation.



Do you understand what's going on with mapserver and so with my svg file ?



Thanks a lot and I’m sorry if my English is not so good to explain my
problems


Regards,


Maria
