Class TGifLZWInfo

class TGifLZWInfo : public TFrameDataBlock;

Description

GIF specific frame data variant which holds LZW compression information.

It can only be used with the GIF decoder (the encoder is not configurable).

Derivation

• TFrameDataBlock - The abstract base class for all format-specific frame data variants

• TGifLZWInfo - GIF specific frame data variant which holds LZW compression information

Members

Defined in TGifLZWInfo:
DuplicateL(), TGifLZWInfo(), iCompressedBytes, iInitialCodeLength

Inherited from TFrameDataBlock:
DataType()

IMPORT_C TGifLZWInfo();

Description

Default constructor for this class.

private: virtual TFrameDataBlock *DuplicateL(CFrameImageData &aFrameImageData) const;

Description

Provides a copy of an object that manages a list of frame and image block data, but not a bitwise copy. It provides a new reference to the object.

Parameters

CFrameImageData &aFrameImageData An object that manages a list of frame and image block data

Return value

TFrameDataBlock *

TInt iInitialCodeLength;

Description

The initial number of bits used in LZW compression.

TInt iCompressedBytes;

Description

The size of compressed frame.
