A general contour is a shape made up of a series of directed line and arc segments followed in order to go from 'start' to 'end' of the contour. You build the shape by adding segments, giving the geometry and start/end connectivity of each one.

Syntax
The CogGeneralContour type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
| CogGeneralContour | Constructs a new instance of this class. | |
| CogGeneralContour(IntPtr) | Constructs a new instance of this class using com pointer. | |
| CogGeneralContour(CogGeneralContour) | Constructs a new instance of this class as a deep copy of the given instance. |
Methods
| Name | Description | |
|---|---|---|
| AddEllipticalArcSegment | Adds an elliptical arc segment before NextSegment. If NextSegment is Nothing, the new segment is added at the end of the contour. If StartFlags has the 'connected' bit set, then StartX and StartY are ignored. This also applies to EndFlags. | |
| AddLineSegment | Adds a new line segment before NextSegment. If NextSegment is Nothing, the new segment is added at the end of the contour. If StartFlags has the 'connected' bit set, then StartX and StartY are ignored. This also applies to EndFlags. | |
| Clone | Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject | |
| Copy | Creates and returns a new general contour, copying the specified parameters of this one. | |
| CopyBase | Copy a graphic and its derived parameters. | |
| CreateContourFromConnectedSegments | Returns a new contour, copying all segments in the connected segment chain that includes ContourSegment, into it. | |
| CreateContourFromSegments | Returns a new contour, copying segments from StartSegment up to, but not including, EndSegment, into it. If EndSegment is Nothing, segments are copied from StartSegment to the end of this contour. | |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) | |
| CreateSegmentIterator | Creates an iterator to iterate over the segments in the contour. InitialSegmentIndex is the index of the segment pointed at by the iterator on return. A value of -1 is interpreted as SegmentCount, and will return the 'End' iterator. | |
| Dispose | ||
| Dispose(Boolean) | ||
| DistanceToPoint | Shortest distance from this shape to the given point. | |
| EnclosingRectangle | Minimum enclosing rectangle of this shape. | |
| Equals | (Inherited from Object.) | |
| Finalize | (Overrides Object Finalize .) | |
| FitToBoundingBox | Adjust the shape's geometric properties so that the shape fits inside passed in rectangle. | |
| FitToImage | Adjust the shape's geometric properties such that its default size is based on the image and its SelectedSpaceName. XScale and YScale are multipliers where 1.0 designates 100% scaling. | |

Remarks
A general contour is a shape made up of a series of directed line and arc segments followed in order to go from the start to the end of the contour. You build the shape by adding segments, giving the geometry and start point and end point connectivity of each one.
For information about manipulating a general contour interactively, see the discussion of general contour shape models.
