beginDecoding
public void beginDecoding()Invokes the superclass method and then sets instance variables on the basis of the metadata set on this decompressor.- Overrides:

decodeRaw
public void decodeRaw(byte[] b, int dstOffset, int pixelBitStride, int scanlineStride) throws IOException Description copied from class:TIFFDecompressorDecodes the source data into the providedbytearrayb, starting at the offset given bydstOffset. Each pixel occupiesbitsPerPixelbits, with no padding between pixels. Scanlines are separated byscanlineStridebytes.- Specified by:
decodeRawin classTIFFDecompressor- Parameters:
b- abytearray to be written.dstOffset- the starting offset inbto be written.pixelBitStride- the number of bits for each pixel.scanlineStride- the number ofbytes to advance between that starting pixels of each scanline.- Throws:
IOException- if an error occurs reading from the sourceImageInputStream.
