[mapserver-users] symbol size limit?

[Rodrigo Cabral]

You can create a circle layer made up of circle shapes with 3 mile radius
based on your original point layer. This way you don't have to worry about
calculating the right size of your symbols. Circle shapes are two-point
shapes, which define the bounding box (left,top)-(right,bottom) for the
circle. Am I right Steve?

Subject: [mapserver-users] symbol size limit?



Hi, all.  I'm trying to change the size of a symbol by changing the map file
parameter via the URL.  It seems to work up to a certain size, but not
beyond it.  It looks as if the limit is around 100 pixels.  Is there a
symbol size limit in MapServer?

Maybe there's a better way to do what I'm trying to do.  I want to draw a 3
mile radius circle around a point.  I'm calculating the appropriate symbol
size based on the map scale right now, but am open to other suggestions.  I
saw a few posts on this topic regarding the use of layer type circle, but I
couldn't get it to work.  Any ideas?  Thanks!


Cheers,
Hannah
