Returns: new instance or nullptr, if this operation is not supported.

Reimplemented from istd::IChangeable.

Reimplemented in i2d::COrientedCircle, and imod::TModelWrap< i2d::CCircle >.

◆ ConvertToPolygon()

virtual bool i2d::CCircle::ConvertToPolygon	(	i2d::CPolygon &	result,
		int	segmentsCount = 0 ) const

virtual

Performs conversion of the circle splitting it to segmentsCount segments to the polygon result.

If segmentsCount <= 0 then number of segments will be calculated automatically, otherwise segmentsCount must be equal or greater then 3.

Reimplemented in i2d::COrientedCircle.

◆ CopyFrom()

◆ GetBoundingBox()

CRectangle i2d::CCircle::GetBoundingBox ( ) const

overridevirtual

Get bounding box of this shape.

Please note, this bounding box is in logical units, the calibration will not be considered.

		double	result[2] ) const

Get points of intersection circle by line.

Parameters

line	line for check.
result	alpha values of intersection points. If returned value is bigger or equals 1 the first value will be set. If returned value is equals 2 the both values will be set.

Returns: number of intersection points. It can be 0, 1 or 2.

◆ GetIntersectionPoints()

int i2d::CCircle::GetIntersectionPoints	(	const CLine2d &	line,
