class SimpleLatexParser.Box

extends java.lang.Object

like TeX, we try to abut aligned Box'es, each of which consists of other Boxes in turn, with a single character as the basic building block. 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.
