Method Detail

getBbox

public Rectangle2D.Float getBbox()

Description copied from class: AbstractGraphReader

Returns the rectangle containing the layed-out graph

Specified by:

getBbox in class AbstractGraphReader

Returns:

the rectangle containing the layed-out graph or null if it is not computed.
