Class EightToSixDotMapper

java.lang.Object
org.daisy.braille.tools.EightToSixDotMapper
public class EightToSixDotMapper extends Object
Provides a utility to map eight dot patterns to six dot patterns. If the resulting patterns are aligned without any row spacing, the patterns will appear the same as the original 8-dot patterns. This can be useful when printing 8-dot files to an embosser using a 6-dot table.
