Good days Mr. Morissette,

I hope it is okey if I ask you a question about mapscript labelling and =
also cc this question to maillist (as you have asked me to do before)

I have tried to label a streets layer in mapserver and succeeded in a =
reasonbale way, names are not perfectly written but I guess it all takes =
some playing around with MINSIZE and/or other values. I will do that.
Before doing that, I tried to do the same thing in my php/mapscript =
which used to run the same mapfile minus the labelling part. I copied =
the mapserver-mapfile's labelled street layer and replaced it into the =
place of the same non-labelled street layer in mapscript-mapfile. This =
is the non-labeled layer of mapscript:

LAYER
  NAME ERENKOY_ORNEKSOKAK_PL_polyline
  GROUP sokaklar
  TYPE line
  DATA ERENKOY_ORNEKSOKAK_PL_polyline
  STATUS ON
  CLASSITEM 'ID'
  CLASS
        EXPRESSION /./
   COLOR 66 34 249
  END

END

I removed the above and put this in its place (which worked with =
mapserver):

LAYER
  NAME ERENKOY_ORNEKSOKAK_PL_polyline
  TYPE LINE
  GROUP sokaklar
  STATUS ON
  DATA ERENKOY_ORNEKSOKAK_PL_polyline
  LABELITEM "ADI"
  CLASS
    NAME "ADI"
    COLOR 161 02 110
    LABEL
      TYPE truetype
#      FORCE true
      FONT arial
      COLOR 0 0 0
        ANGLE AUTO
 #     BACKGROUNDCOLOR 250 250 250=20
      POSITION AUTO
        SIZE 0
        MINSIZE 2
      SIZE 6
    END
  END
END

ADI is the coloumn in dbf which I am trying to use for labelling. After =
this, mapscript stopped rendering images. Then hopelessly, I added a few =
more lines to mapscript mapfile and it restarted to render maps but with =
no labels. So the layer definition became:

LAYER
  NAME ERENKOY_ORNEKSOKAK_PL_polyline
  TYPE line
  GROUP sokaklar
  STATUS ON
  DATA ERENKOY_ORNEKSOKAK_PL_polyline
    CLASSITEM 'ID'
      CLASS
       EXPRESSION /./
      COLOR 66 34 249
      END
   # LABELCACHE OFF
    LABELITEM 'ADI'
      CLASS
   NAME 'ADI'
    #EXPRESSION /./
   COLOR 161 02 110
    LABEL
      TYPE truetype
#      FORCE true
      FONT arial
      COLOR 0 0 0
       ANGLE AUTO
  #   BACKGROUNDCOLOR 250 250 250=20
      POSITION AUTO
        SIZE 0
        MINSIZE 2
      SIZE 8
   END
  END
END

After the advice of Mr. Haseborg from the maillist I added =
$myMap->drawLabelCache($img) line right before  =
$img->saveWebImage(GIF,1,1,0) line.
Still no labels were written. This the point I am stuck at. I have read =
a lot of mail archieves but found no results....

Is there anything else to be added to the php code or mapfile? How can I =
get the labelling to work with mapscript?

(It is killing me to be a php-newbei and mapscript-newbei at the same =
time...)

Thanks in advance:)

Have a nice day

Murat Isik
