Re: [UMN_MAPSERVER-USERS] Class Labels

Hi,

 

I suppose LABELMAXSCALE in the LAYER object should do this for you.

Aihe: [UMN_MAPSERVER-USERS] Class Labels

I'm developing an application and would like the ability to turn a class on at a certain scale, but have it's labels turn on as a user zooms in further.  Is this possible with one layer defition and two classes (one for the data and one for it's labels - both come from the same dataset.)

I set it up how I think it should work but I only get the data drawn without the labels.  Can someone point me in the right direction?  It works with two layers (one as polygon and one as annotation), but I think it should be able to be done with just one layer and two classes. Am I wrong? 

Thanks for your help,
Tim

This is what the layer looks like in the map file:

LAYER
  NAME "MCD Boundaries"
  STATUS default
  DATA basedata/cdreg_ms
  GROUP MCDs
  TYPE POLYGON
  CLASSITEM "Ctv"
  LABELITEM "Mcd_name"
  CLASS
    MAXSCALE 600000
    _expression_ ('[Ctv]' eq 'T')
    OUTLINECOLOR 19 54 234
    STYLE
      SYMBOL 'line'
      SIZE 1
    END
  END
  CLASS
    MAXSCALE 400000
    _expression_ ('[Ctv]' eq 'T')
    LABEL #Town label
      COLOR 19 54 234
      OUTLINECOLOR 255 255 255
      TYPE Bitmap
      SIZE Tiny
      POSITION CC
      PARTIALS False
    END
  END
  METADATA
    CLASSES "no"
    SHOWINLEGEND "nope"
  END
END
