[Mapserver-users] Label background scaling problem

[Havard Tveite]

Mapserver 3.7, nightly 23. january.
(Solaris 2.5.1)
MapServer version 3.7 (development) OUTPUT=PNG OUTPUT=JPEG
  OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER
  SUPPORTS=WMS_CLIENT SUPPORTS=GD2_RGB INPUT=EPPL7 INPUT=SDE

Freetype 2.1.2

I have tried to use labels with a background. I wanted to
scale both the (point) symbols and the labels (with
background) according to the scale of the map (different
scaling for the point symbols and the labels). The symbols
seem to scale OK, the labels seem to scale OK, but the
label background rectangles do not scale the same as the
label text (in my case, they scale "too much", so the
background rectangles become enormous compared to the
text when zooming in). If I set LABEL.MAXSIZE to the same
value as LABEL.MINSIZE and LABEL.SIZE, the text behaves
as expected, but the background box is not affected.

Am I doing something wrong?

(There might also be some problems with label placement
when scaling labels)

I have included some (relevant?) parts from my map-file
below.
