[mapserver-users] how to create symbol on the START and END of aline

[thomas bonfort]

Juan,
If there was a simple and efficient way of rendering start and end
points before version 5.4, we probably would not have gone to the
trouble of implementing the GEOTRANSFORM stuff.

So no, there no other way aside from upgrading or creating a second layer.
