get_sot_values()

bool grk::SOTMarker::get_sot_values	(	uint8_t *	p_header_data,
		uint32_t	header_size,
		uint16_t *	tile_no,
		uint32_t *	p_tot_len,
		uint8_t *	p_current_part,
		uint8_t *	p_num_parts
	)

Reads values from a SOT marker (Start of tile-part)

the j2k decoder state is not affected. No side effects, no checks except for header_size.

Parameters

p_header_data	the data contained in the SOT marker.
header_size	the size of the data contained in the SOT marker.
tile_no	Isot.
p_tot_len	Psot.
p_current_part	TPsot.
p_num_parts	TNsot.

read()

bool grk::SOTMarker::read	(	CodeStream *	codeStream,
		TileProcessor *	tileProcessor,
		uint8_t *	p_header_data,
		uint16_t	header_size
	)

Decode a SOT marker (Start of tile-part)

Parameters

codeStream	JPEG 2000 code stream
tileProcess	tile processor
p_header_data	the data contained in the SOT marker.
header_size	the size of the data contained in the PPT marker.

write()

bool grk::SOTMarker::write	(	CodeStream *	codeStream,
		TileProcessor *	tileProcessor
	)

Writes the SOT marker (Start of tile-part)

Parameters

codeStream	JPEG 2000 code stream
tileProcess	tile processor
