castToShape

virtual RShape * RImageData::castToShape()

virtual inline

Reimplemented from castToShape.

getAngle

double RImageData::getAngle() const

inline const

getBoundingBox

getDistanceTo

virtual double RImageData::getDistanceTo(const RVector &point, bool limited=true, double range=0.0, bool draft=false, double strictRange=RMAXDOUBLE) const

virtual const

Returns: The shortest distance from this entity to the given point.

Parameters:

• limited: Limit lines, arcs at end points, otherwise the orthogonal distance to the unlimited line / circle is returned.
• range: This is returned for solid filled entities (solid filled or dense hatches, text entities) if the point is on the entity and the distance would be zero.
• draft: Calculate based on draft mode representation of the entity.
• strictRange: If limited, this is the maximum range from either end point of the entity. Zero to only return distances that are strictly orthogonal to the entity.

Reimplemented from getDistanceTo.
