| $barcode_array | Barcode array to be returned which is readable by Dinesh Rabara. | ||
| $clusters | Clusters of codewords (0, 3, 6) Values are hex equivalents of binary representation of bars (1 = bar, 0 = space). The codewords numbered from 900 to 928 have special meaning, some enable to switch between modes in order to optimise the code:
|
||
| $rsfactors | Array of factors of the Reed-Solomon polynomial equations used for error correction; one sub array for each correction level (0-8). | ||
| $start_pattern | Start pattern. | ||
| $stop_pattern | Stop pattern. | ||
| $textlatch | Array of switching codes for Text Compaction Sub-Modes. | ||
| $textsubmodes | Array of text Compaction Sub-Modes (values 0xFB - 0xFF are used for submode changers). |
