public int encode(byte[] b, int off, int width, int height, int[] bitsPerSample, int scanlineStride) throws IOException Description copied from class:TIFFCompressorEncodes the supplied image data, writing to the currently setImageOutputStream.- Specified by:
encodein classTIFFCompressor- Parameters:
b- an array ofbytes containing the packed but uncompressed image data.off- the starting offset of the data to be written in the arrayb.width- the width of the rectangle of pixels to be written.height- the height of the rectangle of pixels to be written.bitsPerSample- an array ofints indicting the number of bits used to represent each image sample within a pixel.scanlineStride- the number of bytes separating each row of the input data.- Returns:
- the number of bytes written.
- Throws:
IOException- if the supplied data cannot be encoded by thisTIFFCompressor, or if any I/O error occurs during writing.
