The pattern string returned for a Code 16k barcode consists of 0s and 1s, where the 0s represent bars and the 1s represent spaces. Each row of the barcode image terminates with a newline character (\n or CHR$(10)). The stacked barcode separators extend 7 units in front of the first bar and 1 unit after the last bar and the spaces which allow for this are included in the pattern string. Separator lines are also required above the first row and below the last row.
