Method Summary

BarcodeDimension	calcDimensions(java.lang.String msg) Calculates the dimension of a barcode with the given message. The dimensions are dependant on the configuration of the barcode generator.
void	generateBarcode(CanvasProvider canvas, java.lang.String msg) Generates a barcode using the given Canvas to render the barcode to its output format.
double	getBarHeight(int height) Returns the effective height of a bar with a given logical height.
double	getBarWidth(int width) Returns the effective width of a bar with a given logical width.
BaselineAlignment	getBaselinePosition() Returns the baseline position.
ChecksumMode	getChecksumMode() Returns the current checksum mode.
double	getIntercharGapWidth() Returns the width between encoded characters.
double	getShortBarHeight() Returns the height of a short bar.
double	getVerticalQuietZone() Returns the vertical quiet zone. If no vertical quiet zone is set explicitely, the value if AbstractBarcodeBean.getQuietZone() is returned.
boolean	isDisplayChecksum() Indicates whether the checksum will be displayed as part of the human-readable message.
void	setBaselinePosition(BaselineAlignment baselinePosition) Sets the baseline position.
void	setChecksumMode(ChecksumMode mode) Sets the checksum mode
void	setDisplayChecksum(boolean value) Enables or disables the use of the checksum in the human-readable message.
void	setIntercharGapWidth(double width) Sets the width between encoded characters.
void	setShortBarHeight(double height) Sets the height of a short bar.
void	setVerticalQuietZone(double height) Sets the height of the vertical quiet zone.

Method Detail

setVerticalQuietZone

public void setVerticalQuietZone(double height)

Sets the height of the vertical quiet zone. If this value is not explicitely set the vertical quiet zone has the same width as the horizontal quiet zone.

Overrides:

setVerticalQuietZone in class AbstractBarcodeBean

Parameters:

height - the height of the vertical quiet zone (in mm)

getVerticalQuietZone

public double getVerticalQuietZone()

Returns the vertical quiet zone. If no vertical quiet zone is set explicitely, the value if AbstractBarcodeBean.getQuietZone() is returned.

Overrides:

getVerticalQuietZone in class AbstractBarcodeBean

Returns:

the height of the vertical quiet zone (in mm)

setChecksumMode

public void setChecksumMode(ChecksumMode mode)

Sets the checksum mode

Parameters:

mode - the checksum mode

getChecksumMode

public ChecksumMode getChecksumMode()

Returns the current checksum mode.

Returns:

ChecksumMode the checksum mode

getIntercharGapWidth

public double getIntercharGapWidth()

Returns the width between encoded characters.

Returns:

the interchar gap width

setIntercharGapWidth

public void setIntercharGapWidth(double width)

Sets the width between encoded characters.

Parameters:

width - the interchar gap width

getShortBarHeight

public double getShortBarHeight()

Returns the height of a short bar.

Returns:

the height of a short bar

setShortBarHeight

public void setShortBarHeight(double height)

Sets the height of a short bar.

Parameters:

height - the height of a short bar

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)

getBarHeight

public double getBarHeight(int height)

Returns the effective height of a bar with a given logical height.

Specified by:

getBarHeight in class HeightVariableBarcodeBean

Parameters:

height - the logical height (1=short, 2=tall)

Returns:

double

isDisplayChecksum

public boolean isDisplayChecksum()

Indicates whether the checksum will be displayed as part of the human-readable message.

Returns:

true if checksum will be included in the human-readable message

setDisplayChecksum

public void setDisplayChecksum(boolean value)

Enables or disables the use of the checksum in the human-readable message.

Parameters:

value - true to include the checksum in the human-readable message, false to ignore

generateBarcode

public void generateBarcode(CanvasProvider canvas,
                            java.lang.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

calcDimensions

public BarcodeDimension calcDimensions(java.lang.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

getBaselinePosition

public BaselineAlignment getBaselinePosition()

Returns the baseline position. Indicates whether the bars are top-align or bottom-aligned.

Returns:

the baseline position
