Member Function Documentation

compressTileData()

virtual void KisAbstractTileCompressor::compressTileData ( KisTileData * tileData, quint8 * buffer, qint32 bufferSize, qint32 & bytesWritten )

pure virtual

Compresses a tileData and writes it into the buffer. The buffer must be at least tileDataBufferSize() bytes long. Actual number of bytes written is returned using out-parameter bytesWritten

Parameters

tileData	an existing tile data. It should be created and acquired by the caller.
buffer	the buffer
bufferSize	the size of the buffer
bytesWritten	the number of written bytes

See also

tileDataBufferSize()

Implemented in KisLegacyTileCompressor, and KisTileCompressor2.

decompressTileData()

virtual bool KisAbstractTileCompressor::decompressTileData ( quint8 * buffer, qint32 bufferSize, KisTileData * tileData )

pure virtual

Decompresses a tileData from a given buffer.

Parameters

buffer	the buffer
bufferSize	the size of the buffer
tileData	an existing tile data where the result will be written to. It should be created and acquired by the caller.

Implemented in KisLegacyTileCompressor, and KisTileCompressor2.

    }

readTile()

virtual bool KisAbstractTileCompressor::readTile ( QIODevice * stream, KisTiledDataManager * dm )

pure virtual

Decompresses the tile from the stream. Used by datamanager in load/save routines

See also

decompressTile()

Implemented in KisTileCompressor2, and KisLegacyTileCompressor.

tileDataBufferSize()

virtual qint32 KisAbstractTileCompressor::tileDataBufferSize ( KisTileData * tileData )

pure virtual

Return the number of bytes needed for compressing one tile

Implemented in KisLegacyTileCompressor, and KisTileCompressor2.

writeTile()

virtual bool KisAbstractTileCompressor::writeTile ( KisTileSP tile, KisPaintDeviceWriter & store )

pure virtual

Compresses the tile and writes it into the stream. Used by datamanager in load/save routines

See also

compressTile()

Implemented in KisLegacyTileCompressor, and KisTileCompressor2.
