	BaseElement (const QString &id=QString())

Here is the caller graph for this function:

QVector< int > rdf::PixelGraph::edgeIndexes

(

const QString &

pixelID

)

const

Returns all edges indexes of the current pixel. Each pixel has N edges in the graph. This function returns a vector with all edge indexes of the current pixel. The edge objects can then be retreived using edges()[idx].

Parameters

pixelID

Unique pixel ID.

Returns

A vector with edge indexes.

Here is the caller graph for this function:

QVector< QSharedPointer< PixelEdge > > rdf::PixelGraph::edges

(

const QString &

pixelID

)

const

Returns all edges connected to the pixel with ID pixelID.

Parameters

pixelID

The pixel identifier.

Returns

(

const QVector< int > &

edgeIDs

)

const

Returns a vector with all edges in the ID vector edgeIDs.

Parameters

edgeIDs

The edge IDs.

Returns

QVector< QSharedPointer< PixelEdge > > rdf::PixelGraph::edges

(

)

const

Returns all pixel edges which were found using Delaunay triangulation.

Returns

A vector of PixelEdges which connect 2 pixels each.
