Code128Writer

public Code128Writer()

Method Details

getSupportedWriteFormats

protected Collection<BarcodeFormat> getSupportedWriteFormats()

Overrides:

getSupportedWriteFormats in class OneDimensionalCodeWriter

encode

public boolean[] encode(String contents)

Description copied from class: OneDimensionalCodeWriter

Encode the contents to boolean array expression of one-dimensional barcode. Start code and end code should be included in result, and side margins should not be included.

Specified by:

encode in class OneDimensionalCodeWriter

Parameters:

contents - barcode contents to encode

Returns:

a boolean[] of horizontal pixels (false = white, true = black)

encode

public boolean[] encode(String contents,
 Map<EncodeHintType, ?> hints)

Description copied from class: OneDimensionalCodeWriter

Can be overwritten if the encode requires to read the hints map. Otherwise it defaults to encode.

Overrides:

encode in class OneDimensionalCodeWriter

Parameters:

contents - barcode contents to encode

hints - encoding hints

Returns:

a boolean[] of horizontal pixels (false = white, true = black)

check

private static int check(String contents,
 Map<EncodeHintType, ?> hints)

encodeFast

private static boolean[] encodeFast(String contents,
 int forcedCodeSet)

produceResult

static boolean[] produceResult(Collection<int[]> patterns,
 int checkSum)

findCType

private static Code128Writer.CType findCType(CharSequence value,
 int start)

chooseCode

private static int chooseCode(CharSequence value,
 int start,
 int oldCode)
