  • Constructor Details

    • Code128Bean

      public Code128Bean()
      Create a new instance.

  • Method Details

    • getCodeset

      public int getCodeset()
      Returns the codeset to be used.
      Returns:
      the codeset (see Code128Constants.CODESET_*)

    • setCodeset

      public void setCodeset(int codeset)
      Sets the codesets to use. This can be used to restrict the Code 128 codesets if an application requires that.
      Parameters:
      codeset - the codesets to use (see Code128Constants.CODESET_*)

    • hasFontDescender

      protected boolean hasFontDescender()
      Indicates whether the barcode height calculation should take a font descender into account. This is necessary for barcodes that support lower-case characters like Code128.
      Overrides:
      hasFontDescender in class AbstractBarcodeBean
      Returns:
      true if the implementation has to take font descenders into account

    • getBarWidth

      public double getBarWidth(int width)
      Returns the effective width of a bar with a given logical width.
      Specified by:
      getBarWidth in class AbstractBarcodeBean
      Parameters:
      width - the logical width (1=narrow, 2=wide)
      Returns:
      the effective width of a bar (in mm)

    • generateBarcode

      public void generateBarcode(CanvasProvider canvas, String msg)
      Generates a barcode using the given Canvas to render the barcode to its output format.
      Specified by:
      generateBarcode in interface BarcodeGenerator
      Specified by:
      generateBarcode in class AbstractBarcodeBean
      Parameters:
      canvas - CanvasProvider that the barcode is to be rendered on.
      msg - message to encode

    • calcDimensions

      public BarcodeDimension calcDimensions(String msg)
      Calculates the dimension of a barcode with the given message. The dimensions are dependant on the configuration of the barcode generator.
      Specified by:
      calcDimensions in interface BarcodeGenerator
      Overrides:
      calcDimensions in class AbstractBarcodeBean
      Parameters:
      msg - message to use for calculation.
      Returns:
      BarcodeDimension a BarcodeDimension object containing the barcode's dimensions
