Description

Returns the Binary representation of the raster. If outasin is TRUE, out-db bands are treated as in-db. Refer to raster/doc/RFC2-WellKnownBinaryFormat located in the PostGIS source folder for details of the representation.

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 outasin to TRUE.

Enhanced: 2.1.0 Addition of outasin

Examples

SELECT ST_AsBinary(rast) As rastbin FROM dummy_rast WHERE rid=1;
