# CapturedResultBase

The `CapturedResultBase` class serves as a base class for all captured result types. It is an abstract base class with multiple subclasses, each representing a different type of captured result..

## Definition

*Module:* core

```python
class CapturedResultBase 
```

## Methods

| Method               | Description |

| [`get_original_image_hash_id`](#get_original_image_hash_id) | Gets the hash ID of the original image.|
| [`get_original_image_tag`](#get_original_image_tag) | Gets the tag of the original 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`](#get_error_code) | Gets the error code of the capture operation.|
| [`get_error_string`](#get_error_string) | Gets the error message of the capture operation.|
