[mapserver-dev] hatch fill may not be drawn in multipolygons

[Pierre Giraud]

Hi all,

I'm facing what seems to be a bug with the rendering engine.

In some case, rendering multipolygons using the HATCH type symbol
shows an empty shape on the resulting image. It seems to happen when
no simple geometry (polygon) in the multi-geometry (multipolygon) can
be rendered completely, ie. when all simple geometries are cropped.

Attached, you'll find an archive with :
 - 2 shapefiles :
  * simple.shp only includes simple geometries,
  * multi.shp includes one multi geometries,
 - 1 mapfile with 2 layers, one for each shapefile,
 - 1 README.txt which contains urls to reproduce the bug.

In one case (simple), the rendered shapes have a green stroke and red hatches.
In the other, the rendered shapes only have a green stroke.

Can you confirm that this is a bug so that I can open a ticket in the tracker ?

Regards,
Pierre
