Method Summary

static BufferedImage	toBufferedImage(com.google.zxing.common.BitMatrix matrix) Renders a BitMatrix as an image, where "false" bits are rendered as white, and "true" bits are rendered as black.
static BufferedImage	toBufferedImage(com.google.zxing.common.BitMatrix matrix, MatrixToImageConfig config) As toBufferedImage(BitMatrix), but allows customization of the output.
static void	writeToFile(com.google.zxing.common.BitMatrix matrix, String format, File file) Writes a BitMatrix to a file.
static void	writeToFile(com.google.zxing.common.BitMatrix matrix, String format, File file, MatrixToImageConfig config) As writeToFile(BitMatrix, String, File), but allows customization of the output.
static void	writeToStream(com.google.zxing.common.BitMatrix matrix, String format, OutputStream stream) Writes a BitMatrix to a stream.
static void	writeToStream(com.google.zxing.common.BitMatrix matrix, String format, OutputStream stream, MatrixToImageConfig config) As writeToStream(BitMatrix, String, OutputStream), but allows customization of the output.
