[MS4W-Users] dynamic line pattern

[Brent Fraser]

Robert,
  
   Yep, that is the traditional way.  But it can make for verbose mapfiles, 
and if your data changes frequently it can be a pain to update.
  
 Best Regards,
 Brent Fraser

mapfile 2. Values substituted from database attribute values (AKA 
"attribute

Style from attribute using STYLEITEM:

> STYLEITEM AUTO # OGR driver only (useful for DXF,DWG, format data
> etc)
> - since STYLEITEM is a LAYER object, are multiple classes possible?
> 4. Entire STYLE block from Javascript (STYLEITEM 
"javascript:///home/user/myscript.js" # absolute path) 5. Style from SLD 
[URL] reference
> (&SLD=http://demo.mapserver.org/ogc-demos/map/sld/sld_line_simple.xml)

> You could try #3 (I've never done it but it could work): STYLEITEM 
<attribute>

> Have a look at teh STYLEITEM at https://mapserver.org/mapfile/layer.html
