[mapserver-users] Road shields on Mapserver 7

[Mark Volz]

Hello,

Thank you everyone for your help.  I was able to get road shields to display.  I do have a couple follow up questions:

First,
In the legend, the shield covers up the US Highway line.  Is there a way to remove the shield from the legend, or make it the shield smaller on the legend than it is on the map?

Second,
I would like the roads to be labeled several times alternating between the street name and road shield.  For example, the road shield  should be placed at positions 0, 500, 1000 and the road name should be placed at positions 250, 750, 1250.  I know that I could use REPEATDISTANCE to repeat the labels every 500 pixels, but is there something similar to INITIALGAP that will place the road name at an 250 pixel offset along the line?

I should mention that I was able to cheat by text every 250 pixels, and the shield every 500 pixels.  This works because the text does not draw at positions 0, 500, 1000 because of the label conflict with the road shield, however I was wondering if there is a cleaner way to alternate labels between the street name and road shield.



Sincerely,
Mark Volz,

You certainly can have STYLEs inside labels. I use this to do shields on county roads:

  CLASS
    NAME 'County Road'
    STYLE
      COLOR 255 255 255
      WIDTH 1 MAXWIDTH 1.5 MINWIDTH .75
      OUTLINECOLOR 200 200 200
      OUTLINEWIDTH 1
    END
    LABEL
      STYLE # shield
        SYMBOL 'county_road'
        COLOR 255 255 255
        OUTLINECOLOR 146 146 146
        SIZE 13 MINSIZE 13 MAXSIZE 13
        WIDTH .5 MINWIDTH .5 MAXWIDTH .5
      END
      PRIORITY 1
      TYPE TRUETYPE
      FONT 'myriad_condensed_web'
      SIZE 5 MINSIZE 5 MAXSIZE 5
      COLOR 146 146 146
      MINDISTANCE 150
      ANTIALIAS TRUE
      PARTIALS FALSE
      MINFEATURESIZE 20
    END
  END

Where county_road is referencing a true type font glyph. I'm actually doing some other conversions to remove dependency on ANNOTATION layers and haven't run into any problems yet. Perhaps the problem isn't with the style placement in the label but rather the contents of the style. You'd get a parse error otherwise.

Brent,

I think your right.   I was under the impression that STYLE could be within a LABEL object because since Mapserver 6.2 we could have multiple labels per class.

Anyways, how can I add road shields in Mapserver 7?  Apparently annotation layers have been removed.

Thanks!

I don't think you can put a STYLE inside a LABEL.  You could put it after the LABEL...

Hello,

I am having trouble adding road shields to my map.  The label (and for that matter the entire class) quits drawing as soon as I uncomment the STYLE block under label.  Please let me know What I can do to add road shields to my roads layer.

CLASS
NAME "U.S. Highway"
EXPRESSION "A10"
STYLE
WIDTH 5
COLOR 0 0 0
END #STYLE
STYLE
WIDTH 3
                                COLOR 227 159 2
                END #STYLE
                LABEL
TEXT '[ROADNUM]'
                                SIZE 10 #for AGG
                                FONT vera_sans  #for AGG
                                MINFEATURESIZE 25
                                MINDISTANCE 200
#STYLE   ###  Mapserver quits drawing this layer as soon as I uncomment this block
                                                #SYMBOL './symbols/USHWY.png'
                                #END STYLE
                END #label
END #class

P.S.  Eventually I will want to display both the road number shield and the road name as well.

Thank You
Sincerely,
