Hello,
I am plotting a contour map using Mapserver; the data is in a line type
shapefile. There is a feature in the dbf that describes the line
thickness, so as to allow , say, every fifth contour to be thicker than
the others (or, for that matter, to be a different color). The contour
map is being drawn fine, but being able to "bold" certain lines would be
much better. I have not found a parameter that allows me to control line
thickness. How can I do this?
Thank you,
Don

You could set up a class in your mapfile for each line thickness.
Just use the thickness from the dbf in your expression and then you
can set the thickness (or color or symbol etc) in the class
definition. >
Thank you for your response, but I was not very precise. I know about
classes, and am using it for other layers, but what I don't know is what
parameter within the class hierarchy can be used to control the width of
the line being plotted (I tried size, but all lines still plotted with
the same thickness). I can use color to differentiate the special lines,
but is there anyway to make the selected class plot with a selected line
thickness.
Thank you,
Don
p.s. Happy New Year!
