# DSEnhancedImageResultItem

The `DSEnhancedImageResultItem` class  is an extension of [`DSCapturedResultItem`]({{ site.dcv_ios_api }}core/basic-structures/captured-result-item.html) that represents a enhanced image. This is the most basic unit of the enhanced image result, one of the captured result types that the Capture Vision Router can output.

## Attributes

| Attributes | Type | Description |
| ---------- | ---- | ----------- |
| [`imageData`](#imagedata) | *DSImageData \** | A `DSImageData` object as the image data of a enhanced image. |
| [`originalToLocalMatrix`](#originaltolocalmatrix) | *CGAffineTransform* | The transformation matrix from the original image coordinate system to the local coordinate system. |

The following attributes are inherited from [`DSCapturedResultItem`]({{ site.dcv_ios_api }}core/basic-structures/captured-result-item.html).

| Attributes | Type | Description |
| ---------- | ---- | ----------- |
| [`type`]({{ site.dcv_ios_api }}core/basic-structures/captured-result-item.html#type) | *DSCapturedResultItemType* | The type of the captured result item. |
| [`referencedItem`]({{ site.dcv_ios_api }}core/basic-structures/captured-result-item.html#referenceditem) | *DSCapturedResultItem \** | The referenced captured result item. The reference dependencies is defined in the Capture Vision settings. |
