Class VfCommandPre

java.lang.Object
  org.extex.font.format.vf.command.VfCommand
      org.extex.font.format.vf.command.VfCommandPre

All Implemented Interfaces:

XMLWriterConvertible

public class VfCommandPre
extends VfCommand

VfCommand: pre

A preamble appears at the beginning, followed by a sequence of character definitions, followed by a postamble. More precisely, the first byte of every VF file must be the first byte of the following 'preamble command':

    pre   247  i[1]  k[1]  x[k]  cs[4]  ds[4]
 

Here i is the identification byte of VF, currently 202. The string x is merely a comment, usually indicating the source of the VF file. Parameters cs and ds are respectively the check sum and the design size of the virtual font; they should match the first two words in the header of the TFM file.
