Attributes

Attributes	Type	Description
originalImageHashId	NSString *	The hash id of the original image. You can use this ID to get the original image via IntermediateResultManager class.
originalImageTag	DSImageTag	The DSImageTag of the original image that records information such as the image ID of the original image.
items	NSArray<DSCapturedResultItem> **	An array of DSCapturedResultItems, which are the basic unit of the captured results. A DSCapturedResultItem can be a original image, a decoded barcode, a recognized text, a detected quad, a normalized image or a parsed result. View DSCapturedResultItemType for all available types.
rotationTransformMatrix	CGAffineTransform	The rotation transformation matrix of the original image relative to the rotated image.
errorCode	NSInteger	Get the error code of this result.
errorMessage	NSString *	Get the error message of this result.

originalImageHashId

The hash ID of the original image which can be used to get the original image via the IntermediateResultManager class.

• Objective-C
• Swift

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

2. var originalImageHashId: String { get }
   

originalImageTag

The DSImageTag of the original image that records information such as the image ID of the original image.

• Objective-C
• Swift

1. @property(nonatomic, readonly) DSImageTag *originalImageTag;
   

2. var originalImageTag: ImageTag { get }
   

items

An array of DSCapturedResultItem, which is the basic unit of the captured results. A DSCapturedResultItem can be an original image, a decoded barcode, a recognized text, a detected quad, a normalized image, or a parsed result. View DSCapturedResultItemType for all available types.

• Objective-C
• Swift

1. @property(nonatomic, strong, nullable, readonly) NSArray<DSCapturedResultItem *> *items;
   

2. var items: [CapturedResultItem]? { get }
   

rotationTransformMatrix

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

• Objective-C
• Swift

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

2. var rotationTransformMatrix: CGAffineTransform { get }
   

errorCode

Get the error code of this result. A CapturedResult will carry error information when the license module is missing or the process timeout.

• Objective-C
• Swift

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

2. var errorCode: Int { get }
   

errorMessage

Get the error message of this result. A CapturedResult will carry error information when the license module is missing or the process timeout.

• Objective-C
