Interface Captioner

All Known Implementing Classes:
BasicCaptioner, LatexCaptioner

@Equality
public interface Captioner

Can paint a text string onto a graphics context in horizontal orientation.

It might be better to rework this interface so that the reference position is the origin of the bounding box rather than the start of the baseline which may have a descender. That would make the calculations easier - it's easy to get confused about the origins and height. It would also mean this interface could just return an Icon.

Method Summary
 void drawCaption(String label, Graphics g)
          Draws a caption such that the left end of the text baseline is at the origin of the supplied graphics context.
 Rectangle getCaptionBounds(String label)
          Returns a bounding box for the caption drawn by a corresponding call to drawCaption(java.lang.String, java.awt.Graphics).
 int getPad()
          Returns a suitable padding value for separating captions from the reference position or other graphical elements.
