Class LoadableAfmFont

java.lang.Object
  org.extex.font.format.afm.LoadableAfmFont

All Implemented Interfaces:

BackendFont, BaseFont, ExtexFont, AfmMetricFont, LoadableFont

public class LoadableAfmFont
extends java.lang.Object
implements LoadableFont, BackendFont, AfmMetricFont

Class to load afm fonts.

• The font has no design size; this is set to the size of the font key.
• The EM size is set to the size of the font.
• The font load the font dimen values over FontParameter.
• If the font has no glyph 'space', then ex is used for getSpace().
