pie charts with ANGLEITEM?

[Steve Lime]

Ok, found the problem. The code to use angleitem or sizeitem for point layers was simply not there.
I added and committed to 4.6 and CVS HEAD. Your example works now...

I have attached the shapefile (and the other files linked to it). These files are stored in my folder "data2".

The important parts of my mapfile:

NAME BERLIN3
STATUS ON
SIZE 460 380
SYMBOLSET "symbols/symbols.sym"
FONTSET "fonts/fonts.list"
EXTENT 368711.0 5799080.0 417394.3 5837400.0
UNITS METERS
SHAPEPATH "data2"
IMAGECOLOR 255 255 224
TRANSPARENT OFF
IMAGETYPE PNG

WEB
  TEMPLATE    berlin3.html
  LOG	    	  maps.log
  MINSCALE     50000
  MAXSCALE  300000
  IMAGEPATH "c:/ms4w/tmp/ms_tmp/"
  IMAGEURL "/ms_tmp/"
END

PROJECTION
      "init=epsg:32633" # WGS 84 / UTM zone 33N
END

LAYER
    NAME unternehmen2
    PROJECTION
      "init=epsg:4326"
    END
    TYPE POINT
    DATA pbezirke
    STATUS ON
    CLASS

      STYLE
        SYMBOL "punkt"
        SIZE 40
        COLOR 56 168 0
      END    
      STYLE
        SYMBOL "punkt"
        SIZE 40
        ANGLEITEM JKO_ANGLE
        #ANGLE 300
        COLOR 230 230 0
      END  
      STYLE
        SYMBOL "punkt"
        SIZE 40
        ANGLEITEM GHI_ANGLE
        #ANGLE 245
        COLOR 0 112 255
      END  
      STYLE
        SYMBOL "punkt"
        SIZE 40
        ANGLEITEM DEF_ANGLE
        #ANGLE 75
        COLOR 255 0 0
      END        
    END
END

END

## symbol "punkt" in the symbol file:

SYMBOL
  NAME "punkt"
  TYPE ELLIPSE
  POINTS
    1 1
  END
  FILLED TRUE
END

> Below you'll find the layer of my mapfile. It works with ANGLE. With ANGLEITEM I get only the circles without angles, so there are no pie slices. The angles are stored in the attribute table of the POINT file pbezirke.shp in the fields JKO_ANGLE, GHI_ANGLE and DEF_ANGLE.
