Interface esriArcOrientation

All Superinterfaces:

Serializable

public interface esriArcOrientation
extends Serializable

Describes how to rotate about the arc's center getting from the 'from' point to the 'to' point of an arc.

Remarks

Describes the orientation of a CircularArc. The orientation of a CircularArc is the direction of the arc between the From and To Points. Orientation can be specified in terms of clockwise/counterclockwise orientation or in arc size (Minor/Major). If the From and To Points are located at the same coordinates, clockwise and counterclockwise are ambiguous, and thus, it is necessary to specify the orientation of the arc based on the arc size. The arc is a Minor arc if its Central Angle is less than half the full circle. The arc is Major if its Central Angle is greater than half the circle. If the Central Angle is exactly half a circle, Minor and Major are ambiguous, and thus, it is necessary to specify the orientation of the arc based on the clockwise/counterclockwise direction.

esriArcClockwise        = The arc goes clockwise between the From and To Points

esriArcCounterClockwise = The arc goes counterclockwise between the From and To Points

esriArcMinor            = The Central Angle is less than a half circle

esriArcMajor            = The Central Angle is greater than a half circle

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux
