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.
