beginDecoding

public void beginDecoding()

Description copied from class: TIFFDecompressor

This routine is called prior to a sequence of calls to the decode method, in order to allow any necessary tables or other structures to be initialized based on metadata values. This routine is guaranteed to be called any time the metadata values have changed.

The default implementation computes tables used by the decode method to rescale components to different bit depths. Thus, if this method is overridden, it is important for the subclass method to call super(), unless it overrides decode as well.

Overrides:

beginDecoding in class TIFFDecompressor

               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.

buf - 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.
