Ticket #296 (closed task: fixed)
[wktraster] Implement ST_GetBBox function for raster
|Reported by:||mloskot||Owned by:||jorgearevalo|
Function ST_GetBBox is part of Objective 0.1.6e and shall be implemented:
ST_GetBBox(raster) -> polygon geometry
In the original presentation WKTRasterSpecifications1.0.ppt, slides 31, 32, 33 present what ST_AsPolygon(), ST_Shape(), ST_GetBBOX() and ST_Envelop() should return.
Functions ST_GetBBOX(), ST_Envelop() and ST_Shape() are necessary to implement an elementary version of ST_Intersect() and ST_AsPolygon() is necessary to implement an elementary version of ST_Intersection() returning geometries only.
We definitely need to first write the complete specs of these functions in order to agree on what they are supposed to do. Feedback welcome. Please, post your comments below.
