[Mapserver-dev] Enhancing mapserver line drawing

[woodbri at swoodbridge.com]

Hi all,

What if anything has been discussed about drawing thick antialiased 
lines - I seem to remember a discussion that this was not possible 
because we draw thick lines using a symbol. Also maybe the GD 
antialiasing code was slow. What happens when a thick line gets draw 
in Flash or Postscript, etc. It seems that what we should do is 
define lines based on thickness and styles with one style-type being 
a user defined symbol and then let the appropriate output handler 
decide to implement it as appropriate. Is this happening now? Does 
this make sense? For example, if someone wanted antialiased lines and 
the performance hit was ok, they could then build an antialiasing GD 
output module.

Any thoughts or opinions?
