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 providedbyte
arrayb
, starting at the offset given bydstOffset
. Each pixel occupiesbitsPerPixel
bits, with no padding between pixels. Scanlines are separated byscanlineStride
byte
s.- Specified by:
decodeRaw
in classTIFFDecompressor
- Parameters:
b
- abyte
array to be written.dstOffset
- the starting offset inb
to be written.bitsPerPixel
- the number of bits for each pixel.scanlineStride
- the number ofbyte
s to advance between that starting pixels of each scanline.- Throws:
java.io.IOException
- if an error occurs reading from the sourceImageInputStream
.
