SegmentType Enumeration

In This Topic

Describes the type of line segment. See the Segment.SegmentType property.

Syntax

C#
Visual Basic (Declaration)

public enum SegmentType : System.Enum, System.IComparable, System.IConvertible, System.IFormattable

Public Enum SegmentType 
   Inherits System.Enum
   Implements System.IComparable, System.IConvertible, System.IFormattable

Members

Member	Description
Bezier	A third degree cubic Bezier curve. A non-linear segment defined by four control points. The Bezier curve starts at control point 0 (start point) and ends at control point 3 (end point) The start point and control point 1 define the tangent at the start point. Control point 2 and the end point define the tangent at the end point. The length of these tangent lines and position of the 4 control points determines the shape of the created Bezier curve.
EllipticArc	An elliptic arc is the portion of the boundary of a 2D ellipse that connects two points.
Line	A straight line segment between a start point and end point.

Example

Enumerate the parts of a Polyline

ReadOnlyPartCollection polylineParts = polyline.Parts;

// enumerate the segments to get the length
double len = 0;
IEnumerator<ReadOnlySegmentCollection> segments = polylineParts.GetEnumerator();
while (segments.MoveNext())
{
  ReadOnlySegmentCollection seg = segments.Current;
  foreach (Segment s in seg)
  {
    len += s.Length;

    // perhaps do something specific per segment type
    switch (s.SegmentType)
    {
      case SegmentType.Line:
        break;
      case SegmentType.Bezier:
        break;
      case SegmentType.EllipticArc:
        break;
    }
  }
}

// or use foreach pattern
foreach (var part in polyline.Parts)
{
  foreach (var segment in part)
  {
    len += segment.Length;

    // perhaps do something specific per segment type
    switch (segment.SegmentType)
    {
      case SegmentType.Line:
        break;
      case SegmentType.Bezier:
        break;
      case SegmentType.EllipticArc:
        break;
    }
  }
}
