## ◆ cblkdatabuffersize

OPJ_UINT32 opj_t1::cblkdatabuffersize

Referenced by opj_t1_decode_cblk().

## ◆ data

OPJ_INT32* opj_t1::data

Referenced by opj_t1_allocate_buffers(), opj_t1_cblk_encode_processor(), opj_t1_clbl_decode_processor(), opj_t1_dec_refpass_raw(), opj_t1_dec_sigpass_raw(), opj_t1_decode_cblk(), opj_t1_destroy(), opj_t1_enc_clnpass(), opj_t1_enc_refpass(), opj_t1_enc_sigpass(), and opj_t1_encode_cblk().

## ◆ datasize

OPJ_UINT32 opj_t1::datasize

Referenced by opj_t1_allocate_buffers().

## ◆ encoder

OPJ_BOOL opj_t1::encoder

Referenced by opj_t1_create().

## ◆ flags

opj_flag_t* opj_t1::flags

Flags used by decoder and encoder.

Such that flags[1+0] is for state of col=0,row=0..3, flags[1+1] for col=1, row=0..3, flags[1+flags_stride] for col=0,row=4..7, ... This array avoids too much cache trashing when processing by 4 vertical samples as done in the various decoding steps.
