Class VfFont

java.lang.Object
  org.extex.font.format.vf.VfFont

All Implemented Interfaces:

XMLWriterConvertible

public class VfFont
extends java.lang.Object
implements XMLWriterConvertible

This class read a VF-file.

A VF file is organized as a stream of 8-bit bytes, using conventions borrowed from DVI and PK files. Thus, a device driver that knows about DVI and PK format will already contain most of the mechanisms necessary to process VF files. We shall assume that DVI format is understood; the conventions in the DVI documentation (see, for example, TeX: The Program, part 31) are adopted here to define VF format.
