Member Function Documentation

virtual istd::IChangeable* i2d::CCircle::CloneMe ( CompatibilityMode  mode = CM_WITHOUT_REFS) const
virtual

Make a copy of this object.

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

Reimplemented from i2d::CPosition2d.

Reimplemented in i2d::CArc, and i2d::COrientedCircle.

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.

virtual bool i2d::CCircle::CopyFrom ( const IChangeable &  object,
CompatibilityMode  mode = CM_WITHOUT_REFS 
)
virtual

Reimplemented from i2d::CPosition2d.

Reimplemented in i2d::CArc, and i2d::COrientedCircle.

virtual CRectangle i2d::CCircle::GetBoundingBox ( ) const
virtual

Get bounding box of this shape.

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

Reimplemented from i2d::CPosition2d.

Reimplemented in i2d::CArc.

virtual QByteArray i2d::CCircle::GetFactoryId ( ) const
virtual

Reimplemented from i2d::CPosition2d.

int i2d::CCircle::GetIntersectionAlphas ( const CLine2d line,
double  result[2] 
) const

Get points of intersection circle by line.

Parameters
lineline for check.
resultalpha 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.
int i2d::CCircle::GetIntersectionPoints ( const CLine2d line,
i2d::CVector2d result1,
i2d::CVector2d result2 
) const

Get points of intersection circle by line.

Parameters
lineline for check.
result1intersection point 1. Will be set only if returned 1 or 2.
result2intersection point 2. Will be set only if returned 2.
Returns
number of intersection points. It can be 0, 1 or 2.
virtual bool i2d::CCircle::GetInvTransformed ( const ITransformation2d transformation,
IObject2d result,
ITransformation2d::ExactnessMode  mode = ITransformation2d::EM_NONE,
double *  errorFactorPtr = NULL 
) const
virtual

Calulate inverse transformation of the object into second one.

Please note, that this operation transforms logical coordinates, it means that the calibration will be ignored.

Parameters
modecontrols needed transformation exactness.
errorFactorPtroptional output where approximated length of transformation error vector will be stored. Value 0 means that transformation is exactly done.
resultresult object.
Returns
true, if transformation was done correctly.
