Member Function Documentation

parsePacket()

bool grk::T2Decompress::parsePacket ( uint16_t compno, uint8_t resno, uint64_t precinctIndex, uint16_t layno, PacketCache * compressedPackets )

private

Parses packet.

Parameters

compno	component number
resno	resolution number
precinctIndex	precinct index
layno	layer number
compressedPackets	PacketCache of buffers containing packets

Returns

true if successful

parsePacketData()

void grk::T2Decompress::parsePacketData ( Resolution * res, PacketParser * parser, uint64_t precinctIndex, bool enqueue )

private

Parses packet data.

Parameters

res	Resolution
parser	PacketParser
precinctIndex	precinct index
enqueue	if true, enqueue packet data for concurrent parsing. NOTE: this is only possible if packet length is known before any parsing is done, for example if there is a PLT/PLM marker, or packet header was previously read

parsePackets()

bool grk::T2Decompress::parsePackets	(	uint16_t	tileno,
		PacketCache *	compressedPackets )

Parses tile packets.

Parameters

tileno	index of tile
compressedPackets	PacketCache of buffers containing packets

Returns

true if packets truncated
