Member Function Documentation

◆ call() [1/2]

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

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

Implements ogdf::CCLayoutPackModule.

◆ call() [2/2]

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

Parameters
