Member Function Documentation

call()

virtual void ogdf::ProcrustesSubLayout::call ( GraphAttributes &  GA )

overridevirtual

Computes a layout of graph GA.

This method is the actual algorithm call and must be implemented by derived classes.

Parameters

GA	is the input graph and will also be assigned the layout information.

Implements ogdf::LayoutModule.

copyFromGraphAttributes()

void ogdf::ProcrustesSubLayout::copyFromGraphAttributes ( const GraphAttributes &  graphAttributes, ProcrustesPointSet &  pointSet  )

private

Copies the coords in graph attributes to the point set.

flipY()

void ogdf::ProcrustesSubLayout::flipY ( GraphAttributes &  graphAttributes )

private

Flips all y coordinates.

reverseTransform()

void ogdf::ProcrustesSubLayout::reverseTransform ( GraphAttributes &  graphAttributes, const ProcrustesPointSet &  pointSet  )

private

Does a reverse transform of graph attributes by using the origin, scale and angle in pointset.

rotate()

void ogdf::ProcrustesSubLayout::rotate ( GraphAttributes &  graphAttributes, double  angle  )

private

Rotates all coords in graphAttributes by angle.

scale()

void ogdf::ProcrustesSubLayout::scale ( GraphAttributes &  graphAttributes, double  scale  )

private

Scales all coords in graphAttributes by scale.

scaleToInitialLayout()

bool ogdf::ProcrustesSubLayout::scaleToInitialLayout ( ) const

inline

Should the new layout scale be used or the initial scale? Defaults to true.

Definition at line 122 of file ProcrustesSubLayout.h.

setScaleToInitialLayout()

void ogdf::ProcrustesSubLayout::setScaleToInitialLayout ( bool  flag )

inline

Should the new layout scale be used or the initial scale? Defaults to true.

Definition at line 119 of file ProcrustesSubLayout.h.

translate()

void ogdf::ProcrustesSubLayout::translate ( GraphAttributes &  graphAttributes, double  dx, double  dy  )

private

Moves all coords in graphAttributes by dx, dy.
