ST_AsBinary — Return the Well-Known Binary (WKB) representation of the raster without SRID meta data.
bytea ST_AsBinary(
raster rast, boolean outasin=FALSE)
;
Returns the Binary representation of the raster. If outasin
is TRUE, out-db bands are treated as in-db.
This is useful in binary cursors to pull data out of the database without converting it to a string representation.
By default, WKB output contains the external file path for out-db bands. If the client does not have access to the raster file underlying an out-db band, set |
Enhanced: 2.1.0 Addition of outasin
