AW: [mapserver-users] Oracle Spatial + MS 5.2.0: No drawing of certain objects

Mon Sep 22 00:41:40 PDT 2008

Hallo Paul,

using this patch, mapserver is not ignoring those polygons anymore (polygons, which exists ONLY of a connected sequence of circular arcs that closes on itself).

But instead of rendering those polygons, I get know an error message:

msDrawMap(): Image handling error. Failed to draw layer named 'stgk_gebaeude_orcl'.
msDrawShape(): General error message. Only polygon shapes can be drawn using a POLYGON layer definition.

The first step for rendering those polgons is done: Mapserver recognizes the polygons !

Can I do anything else ?

Greetings
Herbert
