C# 클래스 SharpMap.Converters.WellKnownBinary.GeometryToWKB

Converts a SharpMap.Geometries.Geometry instance to a Well-known Binary string representation.

The Well-known Binary Representation for SharpMap.Geometries.Geometry (WKBGeometry) provides a portable representation of a SharpMap.Geometries.Geometry value as a contiguous stream of bytes. It permits SharpMap.Geometries.Geometry values to be exchanged between an ODBC client and an SQL database in binary form.

The Well-known Binary Representation for SharpMap.Geometries.Geometry is obtained by serializing a SharpMap.Geometries.Geometry instance as a sequence of numeric types drawn from the set {Unsigned Integer, Double} and then serializing each numeric type as a sequence of bytes using one of two well defined, standard, binary representations for numeric types (NDR, XDR). The specific binary encoding (NDR or XDR) used for a geometry byte stream is described by a one byte tag that precedes the serialized bytes. The only difference between the two encodings of geometry is one of byte order, the XDR encoding is Big Endian, the NDR encoding is Little Endian.
