Method Detail

hasFontDescender

protected boolean hasFontDescender()

Description copied from class: AbstractBarcodeBean

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

AbstractBarcodeBean.hasFontDescender()

getBarWidth

public double getBarWidth(int width)

Description copied from class: AbstractBarcodeBean

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)

See Also:

AbstractBarcodeBean.getBarWidth(int)

calcDimensions

public BarcodeDimension calcDimensions(java.lang.String msg)

Description copied from class: AbstractBarcodeBean

Calculates the dimension of a barcode with the given message. The dimensions are dependant on the configuration of the barcode generator.

Specified by:
