addBar

public void addBar(boolean black,
                   int height)

Description copied from interface: ClassicBarcodeLogicHandler

This method indicates a new bar to be painted.

Parameters:

black - True if the bar is to be painted black, False if white/transparent

height - logical weight of the bar. Concrete implementations are free to define this to be height or width. For example, 1 may be interpreted as "narrow bar", 2 as "wide bar" for certain barcodes. While other barcodes might define 1 to be "short bar", 2 as "tall bar". Also, this should not be confused with the effective painting width, or the actual physical size of the bar.
