Parameters
Position
An IPosition65 representing the position and orientation of the object on the terrain.
RadiusX
The radius of the arc along the x-axis in meters.
RadiusY
The radius of the arc along the y-axis in meters
StartAngle
The angle at which the arc begins.
EndAngle
The angle at which the arc ends.
LineColor
The color of the lines that make up the arc. The color value is used to specify color and transparency values. This parameter can be any of the following:
· An IColor65 object.
· A number which represents the color in ABGR format (0xAABBGGRR). The low-order byte contains a value for the relative intensity of red; the second byte contains a value for green; the third byte contains a value for blue. The high-order byte contains a value for alpha.
· A string that represents HTML color format (“#RRGGBB”).
FillColor
The color which fills the arc, if the alpha value is greater than zero. The color value is used to specify color and transparency values. This parameter can be any of the following:
· An IColor65 object.
· A number which represents the color in ABGR format (0xAABBGGRR). The low-order byte contains a value for the relative intensity of red; the second byte contains a value for green; the third byte contains a value for blue. The high-order byte contains a value for alpha.
· A string that represents HTML color format (“#RRGGBB”).
NumofSegments
The number of segments from which the arc is created. The greater the number of segments; the smoother the shape.
GroupID
The Project Tree group in which the arc was created. If it is set to an empty string, the object is created under the root. You can obtain the GroupID by one of the following methods:
· Create the group using IProjectTree65.CreateGroup.
· Find the group, if you know the name, using IProjectTree65.FindItem.
· Traverse the Tree using IProjectTree65 methods such as GetNextItem, until you come to the desired GroupID.
Description
The name of the arc as it appears in the Project Tree. If an empty string is passed into this parameter, TerraExplorer assigns it a unique name.
Return Value
pITerrainArc65
An ITerrainArc65 representing the newly created arc.
Exceptions
