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