Class TtfTablePREP

java.lang.Object
  org.extex.font.format.xtf.tables.AbstractXtfTable
      org.extex.font.format.xtf.tables.TtfTablePREP

All Implemented Interfaces:

XtfGlyphName, XtfTable, XMLWriterConvertible

public class TtfTablePREP
extends AbstractXtfTable
implements XtfTable, XMLWriterConvertible

The 'prep' table stores the instructions that make up the control value program, a set of TrueType instructions that will be executed once when the font is first accessed and again whenever the font, point size or transformation matrix change. It consists of an ordered list of instructions opcodes. Each opcode is a byte. The tag 'prep', referring to the preProgram, is anachronistic but some people still call the control value program the preProgram.

Type	Description
BYTE[ ]	Set of instructions executed whenever point size or font or transformation change
