# DecodedBarcodesResult Class

The `DecodedBarcodesResult` class represents the result of a barcode reading process. It provides access to information about the decoded barcodes, the source image, and any errors that occurred during the barcode reading process.

## Definition

*Module:* dbr

*Inheritance:* [CapturedResultBase](https://www.dynamsoft.com/capture-vision/docs/server/programming/python/api-reference/core/basic-classes/captured-result-base.md) -> DecodedBarcodesResult

```python
class DecodedBarcodesResult(CapturedResultBase):
```

## Methods

| Method               | Description |

| [`get_error_string`](#get_error_string) | Gets the error message of the barcode reading result, if an error occurred. |
| [`get_items`](#get_items) | Gets all the barcode result items. |
| [`get_original_image_hash_id`](#get_original_image_hash_id) | Gets the hash ID of the source image. |
| [`get_original_image_tag`](#get_original_image_tag) | Gets the tag of the source image. |
| [`get_rotation_transform_matrix`](#get_rotation_transform_matrix) | Gets the 3x3 rotation transformation matrix of the original image relative to the rotated image.|

### get_error_code

Gets the error code of the barcode reading result, if an error occurred.

```python
def get_error_code(self) -> int:
```

**Return Value**

Returns the error code of the barcode reading result, or 0 if no error occurred.

### get_error_string

Gets the error message of the barcode reading result, if an error occurred.

```python
def get_error_string(self) -> str:
```

**Return Value**

Returns a string containing the error message of the barcode reading result, or an empty string if no error occurred.

### get_items

Gets all the decoded barcode result items.

```python
def get_items(self) -> List[BarcodeResultItem]:
```

**Return Value**

Returns a `BarcodeResultItem` list.

```python
def get_original_image_hash_id(self) -> str:
```

**Return Value**

Returns a string containing the hash ID of the source image.

### get_original_image_tag

Gets the tag of the source image.
