56 | | * Open: an static method that establishes a connection with PostgreSQL and try to access the table given as argument. Several security checkings must be performed here: if the database has PostGIS support, if the table (or tables) exists, if has a field of raster type, if has a GIST index, etc. (Any more?). Additionally, this method will create the RasterBand objects, needed for fetching the raster bands' data, and create a pointer to the real data. |
