Открытые методы

Метод	Описание
DecodeRow ( byte buffer, int offset, int count, short plane ) : bool	Decodes one row of image data.
DecodeStrip ( byte buffer, int offset, int count, short plane ) : bool	Decodes one strip of image data.
DecodeTile ( byte buffer, int offset, int count, short plane ) : bool	Decodes one tile of image data.
EncodeRow ( byte buffer, int offset, int count, short plane ) : bool	Encodes one row of image data.
EncodeStrip ( byte buffer, int offset, int count, short plane ) : bool	Encodes one strip of image data.
EncodeTile ( byte buffer, int offset, int count, short plane ) : bool	Encodes one tile of image data.
Init ( ) : bool
PackBitsCodec ( Tiff tif, Compression scheme, string name ) : System
PreEncode ( short plane ) : bool	Prepares the encoder part of the codec for a encoding. PreEncode is called after TiffCodec.SetupEncode and before encoding.

Метод	Описание
PackBitsDecode ( byte buffer, int offset, int count, short plane ) : bool
PackBitsEncode ( byte buf, int offset, int cc, short s ) : bool
PackBitsEncodeChunk ( byte buffer, int offset, int count, short plane ) : bool	Encode a rectangular chunk of pixels. We break it up into row-sized pieces to insure that encoded runs do not span rows. Otherwise, there can be problems with the decoder if data is read, for example, by scanlines when it was encoded by strips.
PackBitsPreEncode ( short s ) : bool

Decodes one row of image data.

public DecodeRow ( byte buffer, int offset, int count, short plane ) : bool
buffer	byte	The buffer to place decoded image data to.
offset	int	The zero-based byte offset in at /// which to begin storing decoded bytes.
count	int	The number of decoded bytes that should be placed /// to
plane	short	The zero-based sample plane index.
Результат	bool

Decodes one strip of image data.

public DecodeStrip ( byte buffer, int offset, int count, short plane ) : bool

PreEncode is called after TiffCodec.SetupEncode and before encoding.

public PreEncode ( short plane ) : bool
plane	short	The zero-based sample plane index.
