      • decodeRaw

        public void decodeRaw​(byte[] b,
                              int dstOffset,
                              int bitsPerPixel,
                              int scanlineStride)
                       throws java.io.IOException
        Description copied from class: TIFFDecompressor
        Decodes the source data into the provided byte array b, starting at the offset given by dstOffset. Each pixel occupies bitsPerPixel bits, with no padding between pixels. Scanlines are separated by scanlineStride bytes.
        Specified by:
        decodeRaw in class TIFFDecompressor
        Parameters:
        b - a byte array to be written.
        dstOffset - the starting offset in b to be written.
        bitsPerPixel - the number of bits for each pixel.
        scanlineStride - the number of bytes to advance between that starting pixels of each scanline.
        Throws:
        java.io.IOException - if an error occurs reading from the source ImageInputStream.
