![]() |
Project | Projects this geometry into a new spatial reference. |
![]() |
PutCoords | Sets this line's endpoints to be 'from' and 'to'. |
![]() |
PutWKSCoords | From and To become the new endpoints of this line. Any existing attributes are deleted. |
![]() |
QueryCoords | Copies the endpoints of this line to 'from' and 'to'. |
![]() |
QueryEnvelope | Copies this geometry's envelope properties into the specified envelope. |
![]() |
QueryFromPoint | Copies this curve's 'from' point to the input point. |
![]() |
QueryNormal | Constructs a line normal to a curve from a point at a specified distance along the curve. |
![]() |
QueryPoint | Copies to outPoint the properties of a point on the curve at a specified distance from the beginning of the curve. |
![]() |
QueryPointAndDistance | Finds the point on the curve closest to inPoint, then copies that point to outPoint; optionally calculates related items. |
![]() |
QueryTangent | Constructs a line tangent to a curve from a point at a specified distance along the curve. |
![]() |
QueryToPoint | Copies the curve's 'to' point into the input point. |
![]() |
QueryWKSCoords | Returns the (x,y) coordinates of this line's endpoints. |
![]() |
ReverseOrientation | Reverses the parameterization of the curve ('from' point becomes 'to' point, first segment becomes last segment, etc). |
![]() |
SetEmpty | Removes all points from this geometry. |
![]() |
SnapToSpatialReference | Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system. |
![]() |
SpatialReference | The spatial reference associated with this geometry. |
![]() |
ToPoint | The 'to' point of the curve. |
ILine2.PutWKSCoords Method
From and To become the new endpoints of this line. Any existing attributes are deleted.
Public Sub PutWKSCoords ( _
ByRef from As WKSPoint, _
ByRef to As WKSPoint _
)
public void PutWKSCoords (
ref WKSPoint from,
ref WKSPoint to
);
Remarks
The from and to parameters are WKSPoint structures instead of Point objects. If you are not interested in using or preserving vertex attributes then PutWKSCoords and QueryWKSCoords can be a quicker way to modify and obtain the xy coordinates defining the line.
ILine2.QueryWKSCoords Method
Returns the (x,y) coordinates of this line's endpoints.

ByRef from As WKSPoint, _
ByRef to As WKSPoint _
)
public void QueryWKSCoords (
ref WKSPoint from,
ref WKSPoint to
);
Remarks
The from and to parameters are WKSPoint structures instead of Point objects. If you are not interested in using or preserving vertex attributes then PutWKSCoords and QueryWKSCoords can be a quicker way to modify and obtain the xy coordinates defining the line.
