SV: [mapserver-users] Getting mad - copyright notice - problem solved

[Steve Lime]

Beats me why this would happen but looking at the code the decision to
project is independent
of the decision to transform. Perhaps they shouldn't be unless there is
some funky pixel to pixel
projection that is used. If you file a bug that would be cool if for no
other reason to document
not defining a projection with pixel coordinates.

Thanks Steve, your questions solved the problem (but perhaps not the
mystery). When I removed the project clause (which was unneeded of
course), it works. It seems not to matter if it's first or last. 

If I get time I report this as a (insignificant) bug, I think. Or is
there a good reason to have this behaviour you think?

Wierd, what does the whole mapfile, or at least the other non-layer
pieces look like? The
TRANSFORM directive forces the layer to be handled in pixel coordinates
and really shouldn't
be affected by scale at all. Assuming this is drawn last there should be
no issues with
label collisions.

Are you using label priority at all?
Why the projection obj?

Hello,
Was playing with the suggested copyright notice, and it worked very well
- first mapfile.

Afters extensive testing it appears that below a certain scale my layer
doesn't show up. Or rather; when the BBOX parameter has for instance 
BBOX=11.0,56.0,12.0,57.0  it shows, but not with
BBOX=12.00,57.64,12.09,57.68. Due to the logg (DEBUG level 5) the layer
is not rendered at all.

Can anyone give a clue? Should there be fiddling with MINDISTANCE and
such? 


My Layer definition:

LAYER
  NAME "Base"			# we should always have one layer "base"
  METADATA
    "wms_title"     "Base"
  END
  STATUS DEFAULT
  TYPE ANNOTATION
  PROJECTION
    "init=epsg:4326"   ##recommended
  END

  TRANSFORM ll #set the image origin to be lower left
  FEATURE
    POINTS
      70 -10 #set the offset from lower left position in pixels
    END
    TEXT " (c) 2009 Enera International and www.openstreetmap.org" #this
is your displaying text
  END
  CLASS
    LABEL #defines the font, colors etc. of the text
      FONT "arial"
      TYPE TRUETYPE
      SIZE 8
      BUFFER 1
      COLOR 0 0 0
      BACKGROUNDCOLOR 255 255 255
      FORCE TRUE

    END
  END
  UNITS PIXELS #sets the units for the feature object

END
