Specifies which OCR engines read a page in document-processing pipelines.

```python

from nutrient_sdk import OcrEngine

```

## Values

| Name                  | Value | Description                                                                                                                                                                 |
| --------------------- | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `OcrEngine.FUSION`    | `0`   | Reads each page with every engine the host can run and reconciles their readings word by word. On a host without a GPU execution provider this is the primary engine alone. |
| `OcrEngine.PRIMARY`   | `1`   | Reads each page with the primary engine only.                                                                                                                               |
| `OcrEngine.SECONDARY` | `2`   | Reads each page with the secondary engine only. The secondary engine needs a GPU execution provider.                                                                        |

## Usage Example

```python

from nutrient_sdk import OcrEngine

# Access enum values

value = OcrEngine.FUSION
print(f"Value: {value}")  # Output: Value: OcrEngine.FUSION

print(f"Integer value: {value.value}")  # Output: Integer value: 0

```
