IEllipticArc.QueryCoordsByAngle Method

Returns the center point, starting angle, signed central angle, angle of rotation, ratio of the minor axis to the major axis, and axes.

[Visual Basic .NET]
Public Sub QueryCoordsByAngle ( _
    ByVal ellipseStd As Boolean, _
    ByVal Center As IPoint, _
    ByRef FromAngle As Double, _
    ByRef CentralAngle As Double, _
    ByRef rotationAngle As Double, _
    ByRef semiMajor As Double, _
    ByRef minorMajorRatio As Double _
public void QueryCoordsByAngle (
    bool ellipseStd,
    IPoint Center,
    ref double FromAngle,
    ref double CentralAngle,
    ref double rotationAngle,
    ref double semiMajor,
    ref double minorMajorRatio
HRESULT QueryCoordsByAngle(
  VARIANT_BOOL ellipseStd,
  IPoint* Center,
  System.Double* FromAngle,
  System.Double* CentralAngle,
  System.Double* rotationAngle,
  System.Double* semiMajor,
  System.Double* minorMajorRatio

ellipseStd is a parameter of type bool Center
Center is a parameter of type IPoint* FromAngle [in, out]
FromAngle is a parameter of type double* CentralAngle [in, out]
CentralAngle is a parameter of type double* rotationAngle [in, out]
rotationAngle is a parameter of type double* semiMajor [in, out]
semiMajor is a parameter of type double* minorMajorRatio [in, out]
minorMajorRatio is a parameter of type double*

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


Given the EllipseStd value, returns the Center Point, From Angle, Central Angle, Rotation Angle, semi-Major axis length, and Minor Axis to Major Axis Ratio for the Elliptic Arc.  These are the same parameters used by PutCoordsByAngle to create the Elliptic Arc.  If EllipseStd = TRUE, the From Angle is relative to the rotated semi-Major Axis rather than the X-Axis.
