## ◆ call() [1/2]

 virtual void ogdf::CCLayoutPackModule::call ( Array< DPoint > & box, Array< DPoint > & offset, double pageRatio = 1.0 )
pure virtual

Arranges the rectangles given by box.

The algorithm call takes an input an array box of rectangles with real coordinates and computes in offset the offset to (0,0) of each rectangle in the layout.

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

Parameters
 box is the array of input rectangles. offset is assigned the offset of each rectangle to the origin (0,0). The offset of a rectangle is its lower left point in the layout. pageRatio is the desired page ratio (width / height) of the resulting layout.

Implemented in ogdf::TileToRowsCCPacker.

## ◆ call() [2/2]

 virtual void ogdf::CCLayoutPackModule::call ( Array< IPoint > & box, Array< IPoint > & offset, double pageRatio = 1.0 )
pure virtual

Arranges the rectangles given by box.

The algorithm call takes an input an array box of rectangles with integer coordinates and computes in offset the offset to (0,0) of each rectangle in the layout.

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

Parameters
 box is the array of input rectangles. offset is assigned the offset of each rectangle to the origin (0,0). The offset of a rectangle is its lower left point in the layout. pageRatio is the desired page ratio (width / height) of the resulting layout.

Implemented in ogdf::TileToRowsCCPacker.

## ◆ checkOffsets() [1/2]

 static bool ogdf::CCLayoutPackModule::checkOffsets ( const Array< DPoint > & box, const Array< DPoint > & offset )
static

Checks if the rectangles in box do not overlap for given offsets.

This function serves for checking if the computed offsets are correct in the sense that the rectangles do not overlap in the resulting layout.

Parameters
 box is the array of rectangles. offset is the array of corresponding offsets.

## ◆ checkOffsets() [2/2]

 static bool ogdf::CCLayoutPackModule::checkOffsets ( const Array< IPoint > & box, const Array< IPoint > & offset )
static

Checks if the rectangles in box do not overlap for given offsets.

This function serves for checking if the computed offsets are correct in the sense that the rectangles do not overlap in the resulting layout.

Parameters
 box is the array of rectangles. offset is the array of corresponding offsets.

## ◆ checkOffsetsTP()

template<class POINT >
 static bool ogdf::CCLayoutPackModule::checkOffsetsTP ( const Array< POINT > & box, const Array< POINT > & offset )
staticprivate

Checks if the rectangles in box do not overlap for given offsets.

Parameters
 box is the array of rectangles. offset is the array of corresponding offsets.
Template Parameters
 POINT is the generic point type.

## ◆ operator()() [1/2]

 void ogdf::CCLayoutPackModule::operator() ( Array< DPoint > & box, Array< DPoint > & offset, double pageRatio = 1.0 )
inline

Arranges the rectangles given by box.

The algorithm call takes an input an array box of rectangles with real coordinates and computes in offset the offset to (0,0) of each rectangle in the layout.

Parameters
 box is the array of input rectangles. offset is assigned the offset of each rectangle to the origin (0,0). The offset of a rectangle is its lower left point in the layout. pageRatio is the desired page ratio (width / height) of the resulting layout.

## ◆ operator()() [2/2]

 void ogdf::CCLayoutPackModule::operator() ( Array< IPoint > & box, Array< IPoint > & offset, double pageRatio = 1.0 )
inline

Arranges the rectangles given by box.

The algorithm call takes an input an array box of rectangles with integer coordinates and computes in offset the offset to (0,0) of each rectangle in the layout.

Parameters
 box is the array of input rectangles. offset is assigned the offset of each rectangle to the origin (0,0). The offset of a rectangle is its lower left point in the layout. pageRatio is the desired page ratio (width / height) of the resulting layout.
