[Question] Styling OGR layer

[fmg-lydonchandra]

Hi @szekerest how are you ?
Do you have an example map file to style OGR layer ?
Eg. if I open a DXF file in MapManager, how do I target and style the layer ?

  LAYER
    CONNECTION "dxf1.dxf"
    CONNECTIONTYPE OGR
    NAME "line"
    PROCESSING "GETSHAPE_STYLE_ITEMS=all"
    STATUS ON
    TEMPLATE "query.html"
    TILEITEM "location"
    TYPE LINE
    UNITS METERS
    CLASS
      NAME "Class (0)"
      STYLE
        COLOR 0 0 0
        SIZE 8
      END # STYLE
      TEMPLATE "query.html"
    END # CLASS
    CLASS
      NAME "Class (1)"
      STYLE
        COLOR 0 0 0
      END # STYLE
    END # CLASS
  END # LAYER

ogrinfo output:

OGRFeature(entities):224
  Layer (String) = STOCKPILES
  SubClasses (String) = AcDbEntity:AcDbPolyline
  Linetype (String) = VULCAN_LINE_TYPE_1
  EntityHandle (String) = BFC
  Style = PEN(c:#ffbb00,w:0.3g,p:"0.024g 0.072g")
  LINESTRING Z (1 1 411,2 2 411,3 3 411,4 4  411)

@fmg-lydonchandra You should set auto style for the layer to let mapserver take the feature style into account

[fmg-lydonchandra]

Without using Auto Style, is it possible to style OGRFeature (using our own style)?
eg. when Layer is STOCKPILES make it blue
when Layer is LAYER1 make it red ?

OGRFeature(entities):224
  Layer (String) = STOCKPILES
  SubClasses (String) = AcDbEntity:AcDbPolyline
  Linetype (String) = VULCAN_LINE_TYPE_1
  EntityHandle (String) = BFC
  Style = PEN(c:#ffbb00,w:0.3g,p:"0.024g 0.072g")
  LINESTRING Z (1 1 411,2 2 411,3 3 411,4 4  411)

Hi @szekerest , is there Linux C# Mapscript Nuget package for Mapserver 8.0 that you can upload to nuget?
It looks like the current one is for Mapserver 7.0?

https://www.nuget.org/packages/OSGeo.Mapscript.x64

@lydonchandra There's no official nugets for Mapscript, the referred nuget seems to be an outdated contribution. Creating working nugets for Linux seems to be a challenging task due to the number of unmanaged dependencies, which should also be available on that platform.

Thanks for the info @szekerest , turns out it was quite straightforward to build working Mapscript DLL for my system (Linux based on Debian 11)
