Choosing a Method
You can use two methods to map your graphic image. The
most efficient encoding method depends on how complicated
your graphic image is and whether or not imaging time is a
concern. You may want to experiment with both encoding
methods to get optimal performance.
Hexadecimal Method
With the Hexadecimal method, the dot sequences are
segmented into binary numbers, then converted to hexadecimal
numbers.
A graphic using gray-scaling, several slanted lines, or several
vertical lines typically translates more efficiently with the
Hexadecimal method.
Run Length Encoding Method
With the Run Length Encoding method, the dots are
segmented within a row into sequences where all of the dots
are on or all of the dots are off. Then, you convert the strings
into a letter. This method is more complicated, but can reduce
imaging time for graphics that contain repetitive rows of dots.
A graphic with horizontal lines or very few white-to-black
borders typically translates more efficiently with the Run Length
Encoding method.
