[mapserver-users] Drawing a line

[Fawcett, David]

If you just want to pass the feature in using a URL configuration, you wouldn't need to use mapscript.  Just have the empty layer in your map file and then pass the feature definition in like:
 
 
&map_layer[3]=FEATURE+POINTS+-67.0000012+-16.9999952+-67.0000012+-17.4999950+END+TEXT+'A+test+line'+END&...

	Do you mean "given" as in "submitted via a web page"?  In that case I think I would use Python mapscript to add a LAYER similar to the one I sent below, but using the form variables submitted from the web page as the POINTS values.  Take a look at the chapter on Python Mapscript in the O'Reilley Web Mapping Illustrated book.  It explains it more clearly than I'm probably able to.
	
	Perhaps someone else on the list has another idea.

			You can add a new LAYER with a FEATURE that has the 2 points specified in it, like this:
			
			  LAYER
			    NAME 'line'
			    STATUS DEFAULT
			    TYPE LINE
			    FEATURE
			      POINTS  -67.0000012 -16.9999952
			                    -67.0000012 -17.4999950
			
			      END
			    END
			    CLASS
			      STYLE
			        COLOR 255 0 0
			        WIDTH 2
			      END
			    END # class
			  END # layer
			
			##############
