Method Detail

startBarGroup

public void startBarGroup(BarGroup type,
                          java.lang.String submsg)
Description copied from interface: ClassicBarcodeLogicHandler
This method is called when a new group of bars is about to start. A group of bars may be generated by a character (or group of characters) of the message to be encoded or by a start/end control group.

Specified by:
startBarGroup in interface ClassicBarcodeLogicHandler
Parameters:
type - a constant indicating the type of group. The meaning of the integer values is implementation-dependant.
submsg - In case of parts of the message to be encoded this parameter holds the character or characters being encoded.

endBarGroup

public void endBarGroup()
Description copied from interface: ClassicBarcodeLogicHandler
This method indicates the end of a previously started bar group. The method calls to startBarGroup and endBarGroup form a stack.

Specified by:
endBarGroup in interface ClassicBarcodeLogicHandler

addBar

public void addBar(boolean black,
                   int weight)
Description copied from interface: ClassicBarcodeLogicHandler
This method indicates a new bar to be painted.

Specified by:
addBar in interface ClassicBarcodeLogicHandler
Parameters:
black - True if the bar is to be painted black, False if white/transparent
weight - 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.

                         java.lang.String formattedMsg)

Parameters:
msg - full message to be encoded
formattedMsg - message as it is to be presented in the human-readable part
