Description

A CircularArc is an object that describes a portion of a circle or a complete circle. In geometric terms, a CircularArc is a special case of an EllipticArc, where the major and minor axes are equal. Consequently, every point on the arc is equidistant from the CenterPoint, this distance being the Radius.

                 throws java.io.IOException,
                        AutomationException

Description copied from interface: ICircularArc

Copies the center, 'from' and 'to' points, orientation and major/minor property into the input parameters.

Supported Platforms

Windows, Solaris, Linux

Description

QueryCoords returns the Center Point, the From Point, the To Point, the value of IsCounterClockwise, and the value of IsMinor for the Circular Arc.

Remarks

These are the necessary inputs for PutCoords, except in special cases (half circle, full circle, and Central Angle = 0) where the ArcOrientation must know which of these cases exists to ensure that the desired Circular Arc is unambiguous.

-isCCW stands for "is counter clockwise"

ICircularArc QueryCoords Example

Specified by:: queryCoords in interface ICircularArc

Parameters:: center - A reference to a com.esri.arcgis.geometry.IPoint (in); from - A reference to a com.esri.arcgis.geometry.IPoint (in); to - A reference to a com.esri.arcgis.geometry.IPoint (in); isCCW - The isCCW (in/out: use single element array); isMinor - The isMinor (in/out: use single element array)
Throws:: AutomationException - If the ArcObject component throws an exception.; java.io.IOException - If there are interop problems.

               throws java.io.IOException,
                      AutomationException

Description copied from interface: ICircularArc

Defines this arc by a center point, 'from' and 'to' points, and orientation. If the from and to points do not lie on the same circle, the arc's center point will be adjusted.

Supported Platforms

Windows, Solaris, Linux

Description

Use to create a Circular Arc by specifying the Center Point, From Point, To Point, and ArcOrientation. Care must be taken to ensure that the ArcOrientation is not ambiguous (For half-circles, ArcOrientation must be either Clockwise or CounterClockwise, and when the From Point and To Point are the same, ArcOrientation must be either Minor or Major.).

Remarks

If the FromPoint, ToPoint and CenterPoint specified do not create a circle, the created arc will have its CenterPoint adjusted until the FromPoint and ToPoint can be accomodated on the same circle. Therefore the resultant arcs CenterPoint may not be exactly the same as the input CenterPoint.

ICircularArc PutCoords Example

                             AutomationException

Description copied from interface: ICircularArc

Defines this circular arc by a center point, 'from' angle, signed central angle, and radius.

Supported Platforms

Windows, Solaris, Linux

Description

PutCoordsByAngle creates a Circular Arc given the Center Point, the From Angle, the Central Angle, and the Radius.

Remarks

PutCoordsByAngle is one of the easiest ways to create a desired Circular Arc. However, due to numeric accuracy limitations of computers and trigonometric functions, the From and To Points may be very slightly offset from the expected coordinates. This is important to keep in mind when attempting to connect the endpoints to other segments.

ICircularArc PutCoordsByAngle Example

Specified by:: putCoordsByAngle in interface ICircularArc

Parameters:: cp - A reference to a com.esri.arcgis.geometry.IPoint (in); fromAngle - The fromAngle (in); centralAngle - The centralAngle (in); arcRadius - The arcRadius (in)

project

public void project(ISpatialReference newReferenceSystem)
             throws java.io.IOException,
                    AutomationException

Description copied from interface: IGeometry

Projects this geometry into a new spatial reference.

Supported Platforms

Windows, Solaris, Linux

Description

To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.

A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.

Remarks

Note: If the from/to spatial references have different geographic coordinate systems, the Project method looks for a GeoTransformationsOperationSet. If the set of Geotransformations is present in memory, Project will use it to perform a geographic/datum Transformation. To use a specific geotransformation, use the IGeometry2::ProjectEx method.

Specified by:: project in interface IGeometry

Parameters:: newReferenceSystem - A reference to a com.esri.arcgis.geometry.ISpatialReference (in)
Throws:: AutomationException - If the ArcObject component throws an exception.; java.io.IOException - If there are interop problems.

Description copied from interface: IConstructCircularArc

Constructs an arc from three points. useExistingCenter can be set to true in order to help create a reasonable arc when from and to are identical.

Supported Platforms

Windows, Solaris, Linux

Description

Given a From Point, a Thru Point, and a To Point, the unique CircularArc defined by those points is constructed. The From and To Points become the From and To Points of the CircularArc. The Thru Point is a point that lies somewhere on the CircularArc. For every three points, a single well-defined CircularArc can be created. (The only exception is if all three points are colinear and the Thru Point is not between the From and To Points.)

Remarks

ConstructThreePoints is excellent for creating a CircularArc with exact endpoint coordinates.

The from and to points may be identical, in which case the third point, if it is distinct, will be on the circle and diametrically opposed to the from/to point (orientation will be clockwise).
