.NET Syntax

Visual Basic (Declaration) 
Sub GetArcEdgeData( _
   long Index As System.Integer, _
   double* CenterX As System.Double, _
   double* CenterY As System.Double, _
   double* Radius As System.Double, _
   double* StartAngle As System.Double, _
   double* EndAngle As System.Double, _
   bool* IsCounterclockwiseFlag As System.Boolean _
)
C# 
void GetArcEdgeData( 
   System.int Index,
   out System.double CenterX,
   out System.double CenterY,
   out System.double Radius,
   out System.double StartAngle,
   out System.double EndAngle,
   out System.bool IsCounterclockwiseFlag
)
JavaScript 
GetArcEdgeData( 
   Index : Number
) : {
   CenterX : Number,
   CenterY : Number,
   Radius : Number,
   StartAngle : Number,
   EndAngle : Number,
   IsCounterclockwiseFlag : Boolean
}
COM native C++ 
HRESULT GetArcEdgeData( 
   LONG Index,
   DOUBLE* CenterX,
   DOUBLE* CenterY,
   DOUBLE* Radius,
   DOUBLE* StartAngle,
   DOUBLE* EndAngle,
   VARIANT_BOOL* IsCounterclockwiseFlag
)
C++ 
DSRESULT GetArcEdgeData( 
   long Index,
   double* CenterX,
   double* CenterY,
   double* Radius,
   double* StartAngle,
   double* EndAngle,
   bool* IsCounterclockwiseFlag
)

Parameters

Index
Index of the Arc edge whose data to get (see Remarks)
CenterX[out]
x coordinate of the Arc center
CenterY[out]
y coordinate of the Arc center
Radius[out]
Radius of the Arc from the center coordinates
StartAngle[out]
Angle from the chord that is tangent to the start point of the Arc
EndAngle[out]
Angle from the chord that is tangent to the end point of the Arc
IsCounterclockwiseFlag[out] or Return Value
True if the Arc is drawn in a counterclockwise direction, false if in a clockwise direction

Example

Remarks

This method is valid only when IHatchBoundaryLoop::GetEdgeType is dsHatchEdgeType_e.dsHatchEdgeType_CirArc.

Before calling this method, call IHatchBoundaryLoop::GetEdgesCount to determine a valid value for Index.
