Provides access to members that extend a polyline object.
Members
Name | Description | |
---|---|---|
Densify | Converts this polycurve into a piecewise linear approximation of itself. | |
Dimension | The topological dimension of this geometry. | |
EnumShortestPath | Not implemented. | |
Envelope | Creates a copy of this geometry's envelope and returns it. | |
FromPoint | The 'from' point of the curve. | |
Generalize | Generalizes this polycurve using the Douglas-Peucker algorithm. | |
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 This method is obsolete.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. | |
IsSimpleNonPlanar | Returns false if zero length segments are detected (zero in 2 dimensions), parts at endpoints need to be merged, or need to reorient segments that are pointing against the prevailing orientation for a part. | |
Length | The length of the curve. | |
Project | Projects this geometry into a new spatial reference. | |
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. | |
Reshape | Modifies this polyline by replacing some of its segments with some segments from reshapeSource. | |
ReshapeEx | If bInterpolateReshaped is true, then new vertices will be interpolated based on vertices from the polyline being reshaped. Otherwise, attributes on the reshaping line will be preserved in the output. | |
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. | |
SimplifyEx | Use either planar or network simplify regardless of current attribute awareness. | |
SimplifyNetwork | Removes zero length segments (zero in 2 dimensions), merges parts at endpoints that only connect to each other, reorients segments that are pointing against the prevailing orientation for a part. | |
SimplifyNonPlanar | Removes zero length segments (zero in 2 dimensions), reorients segments that are pointing against the prevailing orientation for a part. | |
Smooth | Converts this curve into a smooth curve containing only Bezier curve segments. | |
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. | |
SplitAtDistance | Introduces a new vertex into this polyline at a specified distance from the beginning of the polyline. | |
SplitAtPoint | Introduces a new vertex into this polyline at the location on it closest to the input point. | |
ToPoint | The 'to' point of the curve. | |
TouchCut | Cut a polyline at locations where the cutter only touches the polyline, in addition to locations where the cutter crosses it. | |
Weed | Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box. |
IPolyline6.IsSimpleNonPlanar Property
Returns false if zero length segments are detected (zero in 2 dimensions), parts at endpoints need to be merged, or need to reorient segments that are pointing against the prevailing orientation for a part.
Public Function get_IsSimpleNonPlanar ( _
ByRef pReason As esriNonSimpleReasonEnum _
) As Boolean
public bool get_IsSimpleNonPlanar (
ref esriNonSimpleReasonEnum pReason
);
Description
The return boolean value indicates whether or not the geometry is simple. If the return is false, the "reason" parameter can be inspected.
IPolyline6.SimplifyNonPlanar Method
Removes zero length segments (zero in 2 dimensions), reorients segments that are pointing against the prevailing orientation for a part.
Public Sub SimplifyNonPlanar ( _
)
public void SimplifyNonPlanar (
);
Description
SimplifyNonPlanar performs the following alterations to the base Polyline:
1) Deletes empty and zero length segments.2) Removes empty parts.3) Makes segment orientation mutually consistent. Ensures that the following FromPoints and preceding ToPoints of connected segments are equal.4) Creates new parts for discontiguous segments or segments with different attributes.5) For a pair of segments in a part that share an endpoint such that one segment has NaN attributes and the other has non-NaN attributes, assign the non-NaN attributes of one to the corresponding NaN slots of the other.
This method is the similar to SimplifyNetwork, except parts are not merged where an end point is shared.
