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

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 byte
s to
advance between that starting pixels of each scanline.
IOException
- if an error occurs reading from the source
