Describes the parts of a geometry that can be located by their proximity to a query point. Specified as a parameter to the HitTest method.
|esriGeometryPartVertex||1||Locates a vertex of the geometry closest to the query point.|
|esriGeometryPartBoundary||4||Locates a point anywhere on the boundary of a polygon, or anywhere on a polyline, that is closest to the query point.|
|esriGeometryPartMidpoint||8||Locates a midpoint of a segment belonging to a polygon or polyline that is closest to the query point.|
|esriGeometryPartCentroid||32||Locates the geometric centroid of a polygon or the center of an envelope closest to the query point.|
|esriGeometryPartEndpoint||16||Locates an endpoint of the polyline closest to the query point.|
|esriGeometryPartSurface||64||Locates a point anywhere on the surface of a polygon or multipatch that is closest to the query ray.|
