Member Data Documentation

uint8_t t85_encode_state_s::bit_planes

The number of bit planes. Always 1 for true T.85

uint32_t t85_encode_state_s::c[128]

uint32_t t85_encode_state_s::c_all

Adaptive template algorithm variables

const uint8_t* t85_encode_state_s::comment

The contents for a COMMENT marker segment, to be added to the image at the next opportunity. This is set to NULL when nothing is pending.

size_t t85_encode_state_s::comment_len

Length of data pointed to by comment

uint32_t t85_encode_state_s::i

int t85_encode_state_s::mx

Maximum ATMOVE window size (0 - 127)

int32_t t85_encode_state_s::new_tx

New TX value, or <0 for analysis in progress

int t85_encode_state_s::newlen

Flag for handling NEWLEN processing.

Encoding parameters

bool t85_encode_state_s::prev_ltp

True if previous row was typical

uint8_t* t85_encode_state_s::prev_row[3]

Pointers to the 3 row buffers

uint8_t* t85_encode_state_s::row_buf

Pointer to a block of allocated memory 3 rows long, which we divide up for the 3 row buffers.

Arithmetic encoder state

int32_t t85_encode_state_s::tx

X-offset of adaptive template pixel

uint32_t t85_encode_state_s::xd
