Method Detail

encode

public ByteMatrix encode(String contents,
                         BarcodeFormat format,
                         int width,
                         int height)
                  throws WriterException

Description copied from interface: Writer

Encode a barcode using the default settings.

Specified by:

encode in interface Writer

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

Returns:

The generated barcode as a ByteMatrix of unsigned bytes (0 == black, 255 == white)

Throws:

WriterException

Since:

BlackBerry API 6.0.0
