## Properties

| Property  | Type |
|---------- | ---- |
| [`start_chars_bytes`](#start_chars_bytes) | *bytes* |
| [`stop_chars_bytes`](#stop_chars_bytes) | *bytes* |

### start_chars_bytes

The start chars of the one-dimensional barcode in a byte array.

### stop_chars_bytes

The stop chars of the one-dimensional barcode in a byte array.

### check_digit_bytes

The check digit chars of the one-dimensional barcode in a byte array.

### start_pattern_range

The position of the start pattern relative to the barcode location.

**Remarks**

The property represents a float list of length 2:
- Index 0: X coordinate of the start position in percentage value.
- Index 1: X coordinate of the end position in percentage value.

### middle_pattern_range

The position of the middle pattern relative to the barcode location.

**Remarks**

The property represents a float list of length 2:
- Index 0: X coordinate of the start position in percentage value.
- Index 1: X coordinate of the end position in percentage value.

### end_pattern_range

The position of the end pattern relative to the barcode location.

**Remarks**

The property represents a float list of length 2:
- Index 0: X coordinate of the start position in percentage value.
- Index 1: X coordinate of the end position in percentage value.
