Update of /thubanrepository/thuban/Extensions/umn_mapserver
In directory doto:/tmp/cvs-serv9291
Modified Files:
mapfile.py
Log Message:
Added ClassGroupDefault to import.
(MF_Symbolset): Removed the extra variable for numsymbols.
(MF_Class.__init__): Added a comment to the exception clause.
Removed the extent init, because it was not needed anymore.
(MF_Layer.add_thubanclass): Added the code to set the class name to the expression value from thuban if no label is defined.
Added the code to export Range expressions from thuban to the mapfile.
(MF_Map.set_extent): Removed the exception and replace it by some if code. If the size of a map is not defined the size will be set to 1,1. This is necessary because if the extent is set, mapscript checks if the size is greater than zero.
(MF_Web): Added the get and set function for the template.
