DSDeskewedImageResultItem

The DSDeskewedImageResultItem class is an extension of DSCapturedResultItem that represents a deskewed image. This is the most basic unit of the deskewed image result, one of the captured result types that the Capture Vision Router can output.

class DeskewedImageResultItem : CapturedResultItem

Attributes

Attributes	Type	Description
`imageData`	DSImageData *	A `DSImageData` object as the image data of a deskewed image.
`sourceDeskewQuad`	DSQuadrilateral *	The quadrilateral from which you get the deskewed image result item.
`crossVerificationStatus`	DSCrossVerificationStatus	The cross verification status of the result item.
`originalToLocalMatrix`	CGAffineTransform	The transformation matrix from the original image coordinate system to the local coordinate system.

The following attributes are inherited from DSCapturedResultItem.

Attributes	Type	Description
`type`	DSCapturedResultItemType	The type of the captured result item.
`referencedItem`	DSCapturedResultItem *	The referenced captured result item. The reference dependencies is defined in the Capture Vision settings.
`targetROIDefName`	NSString	The name of the `TargetROIDef` object which includes a task that generated the result.
`taskName`	NSString	The name of the task that generated the result.

imageData

A DSImageData object for the deskewed image.

Objective-C
Swift

@property (nonatomic, nullable, readonly) DSImageData *imageData

```
var imageData: ImageData? { get }
```

location

The quadrilateral from which you get the deskewed image result item.

Objective-C
Swift

@property (nonatomic, nullable, readonly) DSQuadrilateral *location

```
var location: Quadrilateral? { get }
```

crossVerificationStatus

The cross verification status of the result. The cross verification status determines whether the result item is approved by the multi-frame cross verification mechanism. If approved, the cross verification status is passed. Otherwise, it is failed.

Objective-C
Swift

@property (nonatomic, readonly) DSCrossVerificationStatus crossVerificationStatus;

var crossVerificationStatus: CrossVerificationStatus { get }

originalToLocalMatrix

The transformation matrix from the original image coordinate system to the local coordinate system.

Objective-C
Swift

@property (nonatomic, readonly, assign) CGAffineTransform originalToLocalMatrix;

var originalToLocalMatrix: CGAffineTransform { get }
