Provides access to the coordinates of a line segment in the form of Well Known Structures (WKS).
Members
Name | Description | |
---|---|---|
Angle | The angle between this line and the positive x-axis. | |
Dimension | The topological dimension of this geometry. | |
Envelope | Creates a copy of this geometry's envelope and returns it. | |
FromPoint | The 'from' point of the curve. | |
GeometryType | The type of this geometry. | |
GeoNormalize | Shifts longitudes, if need be, into a continuous range of 360 degrees. | |
GeoNormalizeFromLongitude | Normalizes longitudes into a continuous range containing the longitude. This method is obsolete. | |
GetSubcurve | Extracts a portion of this curve into a new curve. | |
IsClosed | Indicates if 'from' and 'to' points (of each part) are identical. | |
IsEmpty | Indicates whether this geometry contains any points. | |
Length | The length of the curve. | |
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.

)
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.
