# RecognizedTextLinesResult

The `RecognizedTextLinesResult` class represents the result of a text recognition process. It provides access to information about the recognized text lines, the original image, and any errors that occurred during the recognition process.

## Definition

*Module:* dlr

```python
class RecognizedTextLinesResult
```

## Methods

| Method               | Description |
