Field Documentation

◆ m_can_decode

OPJ_BITFIELD opj_j2k_dec::m_can_decode

to tell that a tile can be decoded.

OPJ_UINT32* opj_j2k_dec::m_comps_indices_to_decode

◆ m_default_tcp

opj_tcp_t* opj_j2k_dec::m_default_tcp

store decoding parameters common to all tiles (information like COD, COC in main header)

◆ m_discard_tiles

OPJ_BITFIELD opj_j2k_dec::m_discard_tiles

◆ m_end_tile_x

OPJ_UINT32 opj_j2k_dec::m_end_tile_x

◆ m_end_tile_y

OPJ_UINT32 opj_j2k_dec::m_end_tile_y

◆ m_header_data

OPJ_BYTE* opj_j2k_dec::m_header_data

◆ m_header_data_size

OPJ_UINT32 opj_j2k_dec::m_header_data_size

◆ m_last_sot_read_pos

OPJ_OFF_T opj_j2k_dec::m_last_sot_read_pos

Position of the last SOT marker read.

◆ m_last_tile_part

OPJ_BOOL opj_j2k_dec::m_last_tile_part

Indicate that the current tile-part is assume as the last tile part of the codestream.

It is useful in the case of PSot is equal to zero. The sot length will be compute in the SOD reader function. FIXME NOT USED for the moment

◆ m_numcomps_to_decode

OPJ_UINT32 opj_j2k_dec::m_numcomps_to_decode

◆ m_skip_data

OPJ_BITFIELD opj_j2k_dec::m_skip_data

◆ m_sot_length

to tell the tile part length

◆ m_start_tile_x

OPJ_UINT32 opj_j2k_dec::m_start_tile_x

Only tiles index in the correct range will be decoded.

◆ m_start_tile_y

OPJ_UINT32 opj_j2k_dec::m_start_tile_y

◆ m_state

◆ m_tile_ind_to_dec

OPJ_INT32 opj_j2k_dec::m_tile_ind_to_dec

Index of the tile to decode (used in get_tile).
