[mapserver-users] MapServer 6.2: SIZEUNITS meters - Legend OUTLINE is too big

[Lime, Steve D (DNR)]

The SIZEUNITS are applied based on a computed cellsize for a map request- there is a conversion from meters to pixels based on an extent/image size. Without that same context I don't see how the legend can possibly match the map. Can you pass extent and image size as part of a getLegendGraphic request?

Subject: [mapserver-users] MapServer 6.2: SIZEUNITS meters - Legend OUTLINE is too big

Hello,

I am testing with 6.2 and want to define a WMS with SIZEUNITS meters. My map looks good but I get a very big outline around my polygons-Symbol in the legend.

This is my Layerdefinition:
LAYER
	NAME 'befestigte_flaechen'
	TYPE POLYGON
        ....
	METADATA
		WMS_TITLE 'befestigte Flaechen'
		..
	END

	SIZEUNITS meters

    CLASS
      NAME "1 Fche"
      EXPRESSION "1"
       STYLE
         WIDTH 0.1
         OUTLINECOLOR 58 255 84
         COLOR 250 0 0
       END
    END
    ...
END

The Map looks good with this simple definition in the STYLE-Block.

But the getLegendGraphic-Request looks bad. The OUTLINE of the polygon in the legend is much too big.

When I add  MINWIDTH and MAXWIDTH to the STYLE the legend looks fine.
       STYLE
         WIDTH 0.1
         MINWIDTH 0.1
	 MAXWIDTH 0.2
         OUTLINECOLOR 58 255 84
         COLOR 250 0 0
       END

But I thought that I do not need MINWIDTH and MAXWIDTH when SIZEUNITS meters is set (and no SYMBOLSCALEDENOM is set).
