Problem with iText decodePredictor(byte in, PdfObject dicPar)
I am trying to decompress a stream with filter=flatedecode and decodeparms=[predictor 12 columns 4].
I decoded the stream with FlateDecode(byte in) first.
Then the output is pass in to decodePredictor(byte in, PdfObject dicPar).
I have checked that dicPar is correct.
However, the resulting byte from decodePredictor is incorrect (i'm expecting some readable strings).
