Enclosing class:

LP2

public class LP2.Box

extends java.lang.Object

like TeX, we try to abut aligned Box'es, each of which consists of other Boxes in turn, with single character CharBoxes as the basic building blocks. Boxes are aligned along their baselines, where the integer values (x,y) specify the 75 dpi screen-coordinates of the origin for a box, while the values of w, a, d specify the width, ascent, and descent of the box. The formatting should probably changed to use FIG 2400 dpi world- coordinates instead of screen-coordinates, but the JDK 1.3+ font rendering does not really improve with higher resolution :-(

Unlike TeX, we use the predefined (Postscript) FIG fonts and assume the Unicode encoding. For jfig, a Box may be mapped to a FigCompound that holds FigText objects.
