IEllipticArc.QueryCoords Method

Copies the center and endpoints, angle of rotation, orientation and major/minor properties into the method parameters.

[Visual Basic .NET]
Public Sub QueryCoords ( _
    ByVal ellipseStd As Boolean, _
    ByVal Center As IPoint, _
    ByVal from As IPoint, _
    ByVal to As IPoint, _
    ByRef rotationAngle As Double, _
    ByRef minorMajorRatio As Double, _
    ByRef isCCW As Boolean, _
    ByRef minor As Boolean _
)

[C#]
public void QueryCoords (
    bool ellipseStd,
    IPoint Center,
    IPoint from,
    IPoint to,
    ref double rotationAngle,
    ref double minorMajorRatio,
    ref bool isCCW,
    ref bool minor
);

[C++]

  VARIANT_BOOL ellipseStd,
  IPoint* Center,
  IPoint* from,
  IPoint* to,
  double* rotationAngle,
  double* minorMajorRatio,
  VARIANT_BOOL* isCCW,

Description

Given the EllipseStd value, returns the Center Point, From Point, To Point, Rotation Angle, Minor Axis to Major Axis Ratio, IsCounterClockwise value, and IsMinor value of the Elliptic Arc.  If EllipseStd=TRUE, the From Point and To Point locations are relative offsets from the Center Point rather than the origin.

Remarks

These are the necessary inputs for PutCoords, except in special cases (half ellipse, full ellipse, Central Angle=0, and Minor to Major Ratio=0) where the ArcOrientation must know which of these cases exists to ensure that the desired Elliptic Arc is unambiguous. Any of the output parameters can be set to nil if that info is not desired.

-isCCW stands for "is counter clockwise"
