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.

주의

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.
