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
