Class BlockFormattingContext

java.lang.Object

org.openpdf.layout.BlockFormattingContext

public class BlockFormattingContext
extends Object

This class represents a block formatting context as defined in the CSS spec. Its main purpose is to provide BFC relative coordinates for a FloatManager. This coordinate space is used when positioning floats and calculating the amount of space floated boxes take up at a given y position. NOTE: The translate(int, int) method must be called when a block box in the normal flow is moved (i.e. its static position changes)
