Public Member Functions inherited from rdf::BaseElement
	BaseElement (const QString &id=QString())
	This class keeps an ID to keep track of transformed elements during a processing chain. You can e.g. generate Pixel elements from MserBlobs. After filtering, processing etc. you can map back to the (pixel accurate) MserBlob using this ID. More...

void	setId (const QString &id)
	Sets the (preferably unique) ID. If no ID is set, a unqiue ID is generated and assigned. More...

QString	id () const
	Returns the elment's id. More...

Protected Member Functions
void	updateLine ()

Protected Member Functions inherited from rdf::PixelSet
Polygon	polygon (const QVector< Vector2D > &pts) const
	Returns a poly line along the points defined by angle. If maxAngleThr != -1, points are rejected if the cosine of their enclosing angle is smaller than maxAngleThr. e.g. maxAngleThr = 0 would allow polygon changes of up to 90°. More...
