C# 클래스 BitMiracle.LibTiff.Classic.TiffCodec

Base class for all codecs within the library.

A codec is a class that implements decoding, encoding, or decoding and encoding of a compression algorithm.

The library provides a collection of builtin codecs. More codecs may be registered through calls to the library and/or the builtin implementations may be overridden.

공개 메소드들

메소드	설명
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.
DefStripSize ( int size ) : int	Calculates and/or constrains a strip size.
DefTileSize ( int &width, int &height ) : void	Calculate and/or constrains a tile size
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	Initializes this instance.
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.
Seek ( int row ) : bool	Seeks the specified row in the strip being processed.
SetupDecode ( ) : bool	Setups the decoder part of the codec. SetupDecode is called once before PreDecode.
SetupEncode ( ) : bool	Setups the encoder part of the codec. SetupEncode is called once before PreEncode.
TiffCodec ( Tiff tif, Compression scheme, string name )	Initializes a new instance of the TiffCodec class.
