This works (see code below) but would require 30 x 9 classes where,
previously there were 30.
LABELITEM removed
TEXT added
EXPRESSION changed - added anchorpositiontxt - I would need 9 x classes for
each feature code (30).
I am guessing that there must be a way to achieve this without having to
move from 30 to 270 classes.
=======================================================
#LABELITEM textstring
CLASS
# Building
EXPRESSION (([featurecode] = 10020) And
("[anchorpositiontxt]"="cc"))
TEXT ([textstring])
LABEL
TYPE truetype
FONT arial
SIZE [height]
POSITION cc
COLOR [oscolor]
ANTIALIAS TRUE
ANGLE [orientation]
FORCE TRUE
END # LABEL
END # CLASS
=======================================================

Donald

adatabase
Tommaso,
There are already 30 classes, each with their own attributes, some of which
also come from the database (see example below). I don't think I can also
use CLASSITEM and two EXPRESSIONs.
=======================================================
LABELITEM textstring
CLASS
# Building
EXPRESSION ([featurecode] = 10020)
LABEL
TYPE truetype
FONT arial
SIZE [height]
POSITION cc
#POSITION [AnchorPositionTxt]
COLOR [oscolor]
ANTIALIAS TRUE
ANGLE [orientation]
FORCE TRUE
END # LABEL
END # CLASS =======================================================
Regards,
Donald

Hallo Donald,
you can define a layer with so many classes how are your possible label
positions and filter each class with the value of the attribute
"AnchorPositionTxt"
i.e:
LAYER
NAME "layer"
...
...
CLASSITEM "AnchorPositionTxt"
LABELITEM "name"
CLASS
EXPRESSION "ul"
LABEL
POSITION ul
...
END
END
CLASS
EXPRESSION "lr"
LABEL
POSITION lr
...
END
END
END
Cheers,
Tommaso

Hi List,
I am trying to change a LABEL's POSITION by using an integer without
success.
As far as I can see, the LABEL's POSITION can be any one of the following
constants: enum MS_POSITIONS_ENUM {MS_UL=101, MS_LR, MS_UR, MS_LL, MS_CR,
MS_CL, MS_UC, MS_LC, MS_CC, MS_AUTO, MS_XY , MS_FOLLOW};
I was assuming that I can replace UL with "101" i.e. instead of "POSITION
UL" I use "POSITION 101" but that doesn't work.
I have also tried replacing "POSITION UL" with text values from a database
i.e. "POSITION [AnchorPositionTxt]" where "AnchorPositionTxt" is a string
'UL' but, again, that doesn't work.
Is there a way to set this value dynamically from the database with either
numbers or strings ('UL', LR, etc...)?
Many thanks.
Regards,
Donald Kerr
