#79 compare filter bounding box to all feature geometries Data Stores and Sources PCL 0.12 defect 06/22/06

In postgis.py feature_sql we are only comparing the first feature geometry to a filter bbox, which can lead to erroneous results for the multiple geometry case.

I think there are two solutions

1) OR together query clauses for all feature geometries like

the_centroid && SetSRID('BOX3D...') OR the_geom && SetSRID('BOX3D...')

which is not terribly efficient, but probably also not too costly.

2) we could consider checking the database for a hint about the full feature bounds. Say the table has a "bounds" column of the BOX3D type. We could use this column instead of checking each feature geometry. This would be more efficient, but would require some agreement on what to name this special column. DB admins would also need to be careful to implement rules in their database to keep the bounds accurate.

#87 DiskFeatureStore: 3D Polygons not handled Data Stores and Sources PCL 0.12 defect 08/08/06

Shapefiles with 3D Polygons cause disk.py to throw an exception, as an index is out of range as the GeometryType? is not correctly reported from somewhere down below: 

          schema.append(GeometryProperty('the_geom', homosrs=srs,
                            homotype=GEOM_MAP[ldef.GetGeomType()]))

This is what I see when running it in PDB: 

(Pdb) print ldef.GetGeomType()0).GetGeomType()
-2147483645
(Pdb)

I wondered for a while what was different with this particular shapefile I was using, but it must be that I have Z values in there. 

linux:/www/gisdata/polygons # ogrinfo yunnanpolygon.shp 
INFO: Open of `yunnanpolygon.shp'
using driver `ESRI Shapefile' successful.
1: yunnanpolygon (3D Polygon)

I have not investigate the internals of this any further.

The annoying thing about these error is that that corrupt the entire editing of Primagis maps: as Primagis tries to get all the ZCO data stores into the combobox for selection, when only one of the ZCO datastores is f..cked in some way, it will not let you edit any map and just displays the cryptic 'index error message'.

#90 Spatial index based on shapelib's quadtree Data Stores and Sources PCL 0.12 feature request 10/08/06

We need an index that can be used with Python storage. Memory feature stores, Zope or Plone folders.

#125 Provide Python geo interface Data Stores and Sources feature request 10/13/07

From geometries, features, and sources.

#14 stroke-width, fill-opacity are ignored for some symbolizers Styles and Symbolizers defect 11/11/05

Kai noticed that stroke-width and fill-opacity don't seem to be shown in symbolizer overviews.

#161 Use gdal-config to find GDAL/OGR headers and libs WorldMill defect 04/22/08

Instead of relying on paths coded into setup.py or setup.cfg.

#56 get a feature from a store by its id Data Stores and Sources PCL 0.12 feature request 03/31/06

Something like

feature = store.getfeature(typename, id)

#74 Antialiased line and polygon stroke Styles and Symbolizers feature request 05/04/06

Need to add an "antialiasing" property to Stroke objects. If this is True, then the renderer should turn on antialiasing.

Howard had success with the MapServer? renderer like: 

        elif ISLDPolygonSymbolizer.providedBy(symbolizer):
            f = symbolizer.fill
            s = symbolizer.stroke
            layerob.transparency = _mapscript.MS_GD_ALPHA

            try:
                if f:
                    styleob.color.setHex(f.color)
                    si = classob.insertStyle(mapscript.styleObj())
                    sty2 = classob.getStyle(si)
                    sty2.symbol = 1
                    try:
                        sty2.size = int(s.width)
                    except AttributeError:
                        pass
                    sty2.outlinecolor.setHex(s.color)
                    sty2.antialias = _mapscript.MS_TRUE
                else:
                    styleob.outlinecolor.setHex(s.color)
                    try:
                        styleob.width = int(s.width)
                    except AttributeError:
                        pass

            except:
                raise
