[mapserver-users] Vector symbol drawing problem

Tue Aug 10 08:50:23 PDT 2010

Is there a TrueType symbol that you could use in place of the simple vector symbol?  You could even potentially create your own if you can't find an existing one.

David,

As you may have noticed, I've just submitted a bug for this - ticket #3511.  In the meantime, I'm drawing thin horizontal rectangles instead, although these don't get rendered either if they're less than 0.05 units (pixels?) high!  :-(

Thomas is the guy who knows what he is talking about, he wrote much of the agg rendering code.  

I hadn't had enough coffee this morning to give you a reasonable answer...

David.

Hi David,

Just in case it makes any difference, I'm attempting to draw the UK Ordnance Survey MasterMap Topography Layer.  Here's a sample map file that demonstrates the problem - although for some reason the VerticalLine symbol now gets drawn horizontally!

MAP
  NAME "IPMap"
  EXTENT 529445 179961 529555 180038  # The Mall, London
  SIZE 1200 1200
  UNITS meters
  IMAGETYPE PNG24
  IMAGECOLOR 190 255 255
  FONTSET "Fonts.lst"
  SHAPEPATH "."
  PROJECTION
    "init=epsg:27700"  # OSGB39
  END

  SYMBOL
    NAME "HorizontalLine"
    TYPE vector
    POINTS
       0 0
       1 0
    END
  END

  SYMBOL
    NAME "VerticalLine"
    TYPE vector
    POINTS
       0 0
       0 1
    END
  END

  LAYER
    NAME "TopographicPoint"
    STATUS off
    TYPE point
    UNITS meters
    MINSCALEDENOM 0
    MAXSCALEDENOM 3125
    TRANSPARENCY alpha
    TILEINDEX "OSMasterMap/TopographyLayer/TopographicPoint"

    CLASS
      STYLE
        SYMBOL "HorizontalLine"
        COLOR 0 0 0
        WIDTH 10
      END
    END
  END
END

Regards,

Jez

What does the rest of the map file look like?  What is your map extent?

David.

Hello fellow MapServer users!

I'm trying to draw a really simple vector SYMBOL using MapServer - it's just
a straight line!  I expected this to be easy, but I can only get MapServer
to render vertical lines!  The following SYMBOL definition correctly draws a
vertical line:

  SYMBOL
    NAME "VerticalLine"
    TYPE VECTOR
    POINTS
       0 0
       0 1
    END
  END

However, when I change this to draw a horizontal line nothing is output:

  SYMBOL
    NAME "HorizontalLine"
    TYPE VECTOR
    POINTS
       0 0
       1 0
    END
  END

Is this a bug or am I doing something wrong?

Jez
