Public Attributes | |
t4_row_read_handler_t | row_read_handler |
Callback function to read a row of pixels from the image source. | |
void * | row_read_user_data |
Opaque pointer passed to row_read_handler. | |
int | encoding |
The type of compression used. | |
int | image_width |
Width of the current page, in pixels. | |
int | min_bits_per_row |
The minimum number of encoded bits per row. This is a timing thing for hardware FAX machines. | |
int | max_rows_to_next_1d_row |
The current maximum contiguous rows that may be 2D encoded. | |
int | image_length |
Length of the current page, in pixels. | |
int | bytes_per_row |
The current number of bytes per row of uncompressed image data. | |
int | rows_to_next_1d_row |
Number of rows left that can be 2D encoded, before a 1D encoded row must be used. | |
int | row_bits |
The current number of bits in the current encoded row. | |
bool | row_is_2d |
This variable is set if we are treating the current row as a 2D encoded one. | |
uint32_t | tx_bitstream |
Encoded data bits buffer. | |
int | tx_bits |
The number of bits currently in tx_bitstream. | |
uint8_t * | bitstream |
The working chunk of the output bit stream. | |
int | bitstream_iptr |
Input pointer to the output bit stream buffer. | |
int | bitstream_optr |
Output pointer to the output bit stream buffer. | |
int | bit_pos |
Pointer to the bit within the byte containing the next image bit to transmit. | |
uint32_t * | cur_runs |
Black and white run-lengths for the current row. | |
uint32_t * | ref_runs |
Black and white run-lengths for the reference row. | |
int | ref_steps |
The number of runs currently in the reference row. | |
int | min_row_bits |
The minimum bits in any row of the current page. For monitoring only. | |
int | max_row_bits |
The maximum bits in any row of the current page. For monitoring only. | |
int | compressed_image_size |
The size of the compressed image, in bits. | |
logging_state_t | logging |
Error and flow logging control. | |
T.4 1D, T4 2D and T6 compressor state.
