Finally I got the solution. I have created an arrow(->) on roads properly. I
wont be able to fine CHARACTER CODE of(->) in required FONT SET. But now i
got it. For reference I m giving you the solution if anybody requires it:
I have modified the symbol definition:
SYMBOL
NAME "arrow"
TYPE TRUETYPE
FONT arial
FILLED true
ANTIALIAS true
CHARACTER '→'
GAP -50
END
Ans in layer definition:
LAYER
NAME "major road"
CONNECTIONTYPE db
CONNECTION "usename/password at mapdb"
DATA "GEOM FROM road "
CLASSITEM "ONEWAY"
LABELITEM "STREETNAME"
TYPE Line
STATUS ON
CLASS
NAME "MAJOR-ROADS"
MAXSCALE 260000
MINSCALE 0
EXPRESSION ([ONEWAY] = 1)
style
SYMBOL "arrow"
SIZE 10
COLOR 82 82 82
ANTIALIAS true
end
END
END # Layer
Now this will work fine. Thank you for everyone's guidance & suggestions.
I am getting symbol on the road, but its not coming as it was in image.gif
file. The symbol get displayed in rectangular form. I am not getting where
theres a problem. Please help me out.
My symbol definition is as follows:
SYMBOL
NAME "newarrow"
TYPE PIXMAP
IMAGE "105.gif"
GAP -70
END
And Layer is as:
LAYER
NAME "road"
CONNECTIONTYPE db
CONNECTION "username/password"
DATA "GEOM FROM road"
CLASSITEM "ONEWAY"
LABELITEM "STREETNAME"
TYPE Line
STATUS ON
CLASS
NAME "MAJOR-ROADS"
MAXSCALE 260000
MINSCALE 0
EXPRESSION ([ONEWAY] = 1)
style
SYMBOL "newarrow"
SIZE 8
COLOR 119 136 153
ANTIALIAS true
end
END
END # Layer
