Public Methods

Method	Description
CCITTCodec ( Tiff tif, Compression scheme, string name ) : System
Cleanup ( ) : void	Cleanups the state of the codec. Cleanup is called when codec is no longer needed (won't be used) and can be used for example to restore tag methods that were substituted.
Close ( ) : void	Flushes any internal data buffers and terminates current operation.
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
PostEncode ( ) : bool	Performs any actions after encoding required by the codec. PostEncode is called after encoding and can be used to release any external resources needed during encoding.
PreDecode ( short plane ) : bool	Prepares the decoder part of the codec for a decoding. PreDecode is called after SetupDecode and before decoding.
PreEncode ( short plane ) : bool	Prepares the encoder part of the codec for a encoding. PreEncode is called after SetupEncode and before encoding.
SetupDecode ( ) : bool
SetupEncode ( ) : bool	Setups the encoder part of the codec. SetupEncode is called once before PreEncode.
