TIFFInputStream

public TIFFInputStream(InputStream in,
 int inSize,

 FilterParams diparams)

Creates an input stream filter.

Parameters:

in - the input stream

 FilterParams p)

TIFFInputStream

public TIFFInputStream(InputStream in)

Method Details

fill

public void fill()

Set the TIFF predictor. This must be done before reading any bytes. --------- TIFF pre-compression/post-decompression predictors -------- LZW and Flate use these predictors. NOTE: The predictors are all very slow. Hor. differencing, for example, is 100% slower compressing and 600% slower expanding than no predictor. Predictors: 0 (no prediction) 1 DEFAULT (no prediction) Component sizes 1, 2, 4, and 8: 2 hor. differencing (see TIFF 6.0 spec) Component size 8 only: 3..9 unused 10 PNG code 0: None 11 PNG code 1: Sub 12 PNG code 2: Up 13 PNG code 3: Average 14 PNG code 4: Paeth 15 PNG optimum (best efforts)
