[MS4W-Users] dynamic line pattern

[Brent Fraser]

Sven,
  
   My old notes on styling:
  
      ------ Mapserver Styling Strategies ------
1. Values hard-coded in mapfile
2. Values substituted from database attribute values (AKA "attribute 
binding")
    - not all values can use [attribute] as a value, eg PATTERN
3. Entire Style from attribute using STYLEITEM:
    STYLEITEM "mystyleattribute" #  Mapserver or OGR format
    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
  
 Best Regards,
 Brent Fraser
