Method Detail

encode

public BitMatrix encode(String contents,
                        BarcodeFormat format,
                        int width,
                        int height,
                        Map<EncodeHintType,?> hints)
                 throws WriterException

Description copied from class: OneDimensionalCodeWriter

Encode the contents following specified format. width and height are required size. This method may return bigger size BitMatrix when specified size is too small. The user can set both width and height to zero to get minimum size barcode. If negative value is set to width or height, IllegalArgumentException is thrown.

Specified by:

encode in interface Writer

Overrides:

encode in class OneDimensionalCodeWriter

Parameters:

contents - The contents to encode in the barcode

format - The barcode format to generate

width - The preferred width in pixels

height - The preferred height in pixels

hints - Additional parameters to supply to the encoder

Throws:

WriterException

encode

public byte[] encode(String contents)

Description copied from class: OneDimensionalCodeWriter

Encode the contents to byte 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

Returns:

a byte array of horizontal pixels (0 = white, 1 = black)
