IMcRegionsSetEllipse Method

Sub SetEllipse ( 
	lIndex As Integer,
	Cx As Double,
	Cy As Double,
	MajAx As Double,
	Optional MinAx As Double = 0,
	Optional MajAngle As Double = 0
)

The FeatureType will have the mcftEllipseAny bit set in its Type. The actual Type be mcftEllipse, mcftFreeEllipse, mcftCircle. The Type is determined from the assigned ellipse parameters and the state of the mcofDefaultFreeEllipse and mcofDefaultCircle bits of the OptionFlags. If both of these bits are clear (this is the default state), then any SetEllipse call made with the MajAngle argument zero will be of Type mcftEllipse. The McGraphObjEllipse linked to features of Type mcftEllipse cannot be rotated by the user (i.e., the mcgsAllowRotate bit of their Style property is cleared). A SetEllipse call with MajAngle non-zero or with the mcofDefaultFreeEllipse bit of OptionFlags set, will create a feature of Type mcftFreeEllipse. The McGraphObjEllipse linked to features of Type mcftFreeEllipse can be rotated by the user (i.e., the mcgsAllowRotate bit of their Style property is set). If the mcofDefaultCircle bit of the OptionFlags property is set, then a SetEllipse call with MajAx equal to MinAx will create a feature of Type mcftCircle. Features of this type are linked to McGraphObjCircle linked instances.. Note that features of Type mcftCircle may have nonzero MajAngle values: in this case, the angle specifies the angle at which any marking radial or diameter line is to be drawn on a linked McGraphObjCircle.
