      • toBufferedImage

        public 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. Uses default configuration.
        参数:
        matrix - BitMatrix to write
        返回:
        BufferedImage representation of the input

      • toBufferedImage

        public static BufferedImage toBufferedImage​(com.google.zxing.common.BitMatrix matrix,
                                            cn.t.util.media.code.zxing.MatrixToImageConfig config)
        As toBufferedImage(BitMatrix), but allows customization of the output.
        参数:
        matrix - BitMatrix to write
        config - output configuration
        返回:
        BufferedImage representation of the input

      • writeToPath

        public static void writeToPath​(com.google.zxing.common.BitMatrix matrix,
                               String format,
                               Path file)
                        throws IOException
        Writes a BitMatrix to a file with default configuration.
        参数:
        matrix - BitMatrix to write
        format - image format
        file - file Path to write image to
        抛出:
        IOException - if writes to the stream fail

                               cn.t.util.media.code.zxing.MatrixToImageConfig config)
                        throws IOException
        As writeToPath(BitMatrix, String, Path), but allows customization of the output.
        参数:
        matrix - BitMatrix to write
        format - image format
        file - file Path to write image to

        抛出:
        IOException - if writes to the file fail

      • writeToStream

        public static void writeToStream​(com.google.zxing.common.BitMatrix matrix,
                                 String format,
                                 OutputStream stream)
                          throws IOException
        Writes a BitMatrix to a stream with default configuration.
        参数:
        matrix - BitMatrix to write
        format - image format
        stream - OutputStream to write image to
        抛出:
        IOException - if writes to the stream fail
