Member Function Documentation

decode_packet()

bool grk::T2Decode::decode_packet ( TileCodingParams *  tcp, PacketIter *  pi, ChunkBuffer *  src_buf, uint64_t *  data_read  )

private

Decode a packet of a tile from a source buffer.

Parameters

tcp	Tile coding parameters
pi	Packet iterator
src_buf	source buffer
data_read	amount of data read

Returns

true if packet was successfully decoded

decode_packets()

bool grk::T2Decode::decode_packets	(	uint16_t	tileno,
		ChunkBuffer *	src_buf,
		uint64_t *	data_read
	)

Decode the packets of a tile from a source buffer.

Parameters

tileno	number that identifies the tile for which to decompress the packets
src_buf	source buffer
data_read	amount of data read

Returns

true if successful
