Member Function Documentation

QPolygonF ito::Shape::basePoints ( ) const

base points are various points that help to define the geometry in a precise description.

QPolygonF ito::Shape::contour ( bool  applyTrafo = true,
qreal  tol = -1.0 
) const

returns the enclosing contour as polygon. If the shape is elliptic, an approximation is applied, where tol is the maximum distance between real contour and a line segment of the polygon (if -1.0, the tolerance is defined to be 1% of the smaller diameter of the ellise
