C# 클래스 BitMiracle.LibTiff.Classic.Internal.CodecWithPredictor

Codecs that want to support the Predictor tag should inherit from this class instead of TiffCodec. Such codecs should not override default TiffCodec's methods for decode|encode setup and encoding|decoding of row|tile|strip. Codecs with predictor support should override equivalent methods provided by this class. If codec wants to provide custom tag get|set|print methods, then it should pass pointer to a object derived from TiffTagMethods as parameter to TIFFPredictorInit

PredictorDecodeRow ( byte buffer, int offset, int count, short plane ) : bool	Decode a scanline and apply the predictor routine.
PredictorDecodeTile ( byte buffer, int offset, int count, short plane ) : bool	Decode a tile/strip and apply the predictor routine. Note that horizontal differencing must be done on a row-by-row basis. The width of a "row" has already been calculated at pre-decode time according to the strip/tile dimensions.
