DSDecodedBarcodesResult Class

DSDecodedBarcodesResult represents a collection of DSBarcodeResultItem, the basic unit of a decoded barcode result. It provides access to information about the decoded barcodes of an image/frame, the source image/frame, and any errors that occurred during the barcode reading process.

Attributes

Attributes	Type	Description
`items`	NSArray<DSBarcodeResultItem>	An array of `DSBarcodeResultItem`, which is the basic unit of the captured results.
`originalImageTag`	DSImageTag *	The `ImageTag` of the original image.
`originalImageHashId`	NSString *	The hash ID of the original image.
`rotationTransformMatrix`	CGAffineTransform	The rotation transformation matrix of the original image relative to the rotated image.
`errorCode`	NSInteger	The error code should something go wrong during the barcode recognition process.
`errorMessage`	NSString *	The error message associated with the error code should something go wrong during the barcode recognition process.

items

An array of DSBarcodeResultItem, which is the basic unit of the barcode capture results.

Objective-C
Swift

@property(nonatomic, nullable, readonly) NSArray<DSBarcodeResultItem *> *items;

var items: [DSBarcodeResultItem]? { get }

originalImageHashId

The hash ID of the original image. You can use this ID to get the original image via DSIntermediateResultManager class.

Objective-C
Swift

@property(nonatomic, copy, readonly) NSString *originalImageHashId;

var originalImageHashId: String? { get }

originalImageTag

The ImageTag of the source image. The image tag contains info about the image such as the image ID and the image capture distance mode.

Objective-C
Swift

@property(nonatomic, readonly) DSImageTag *originalImageTag;

var originalImageTag: DSImageTag? { get }

rotationTransformMatrix

The rotation transformation matrix of the original image relative to the rotated image. Please see CGAffineTransform for more info.

Objective-C
Swift

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

var rotationTransformMatrix: CGAffineTransform { get }

errorCode

The error code associated with the result should something go wrong during the barcode recognition process. For the full list of possible errors, please visit ErrorCode.

Objective-C
Swift

@property (nonatomic, assign, readonly) NSInteger errorCode;

```
var errorCode: Int { get }
```

errorMessage

The error message associated with the error code should something go wrong during the barcode recognition process. For the full list of possible errors, please visit ErrorCode.

Objective-C
Swift

@property (nonatomic, assign, readonly) NSString * errorMessage;

```
var errorMessage: String? { get }
```
