매개 변수

  • distance
    유형: System.Double
    A double that specifies the distance from the SqlGeometry instance around which to calculate the buffer.

반환 값

유형: Microsoft.SqlServer.Types.SqlGeometry
A SqlGeometry object that represents the union of all points whose distance from the calling SqlGeometry is less than or equal to the specified value.


STBuffer calculates a buffer in the same manner as BufferWithTolerance, that specifies tolerance = distance * .001 and relative = true.

A negative buffer removes all points within the given distance of the boundary of the SqlGeometry.
