Method Detail

initialize

private void initialize()
                 throws IOException

Throws:

IOException

decodeRaw

public void decodeRaw(byte[] b,
             int dstOffset,
             int bitsPerPixel,
             int scanlineStride)
               throws 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.

Overrides:

decodeRaw in class TIFFJPEGDecompressor

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:

IOException - if an error occurs reading from the source ImageInputStream.

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class TIFFJPEGDecompressor

Throws:

Throwable
