DSDecodedBarcodesUnit Class

DSDecodedBarcodesUnit extends the DSIntermediateResultUnit class and represents a unit which holds the decoded barcodes.

Definition

Assembly: DynamsoftCaptureVisionBundle.xcframework

• Objective-C
• Swift

1. NS_SWIFT_NAME(DecodedBarcodesUnit)
   @interface DSDecodedBarcodesUnit: DSIntermediateResultUnit
   

2. class DecodedBarcodesUnit: DSIntermediateResultUnit
   

Methods

The following methods are inherited from DSIntermediateResultUnit.

| Method | Description | |——- |————-| | getLocation | Gets the location of the region object, represented as a quadrilateral. | | getReferencedElement | Gets the referenced element that supports the capturing of this element. | | getRegionObjectElementType | Gets the type of the region object element, defined by the enumeration DSRegionObjectElementType. | | getImageData | Gets the image data of this region object element. |

getDecodedBarcodes

Returns all the barcodes that are decoded from the image as an array of DSDecodedBarcodeElement.

• Objective-C
• Swift

1. - (nullable NSArray<DSDecodedBarcodeElement*>*)getDecodedBarcodes
   

2. func getDecodedBarcodes() -> [DSDecodedBarcodeElement]?
   

Return Value

An array of DSDecodedBarcodeElement as the decoded barcodes.

getCount

Returns the number of barcodes that are decoded from the image.

• Objective-C
• Swift

1. - (NSInteger)getCount
   

2. func getCount() -> NSInteger
   

Return Value

An integer representing the number of barcodes that are decoded from the image.

getDecodedBarcode

Returns the DSDecodedBarcodeElement at the specified index. This is the same as accessing the same index of the result array from getDecodedBarcodes.

• Objective-C
• Swift

1. - (nullable DSDecodedBarcodeElement*)getDecodedBarcode:(NSInteger)index
   

2. func getDecodedBarcode(index: NSInteger) -> DSDecodedBarcodeElement?
   

Parameters

[in] index: The index of the decoded barcode from the array of decoded barcodes.

Return Value

A DSDecodedBarcodeElement representing the decoded barcode.

removeAllDecodedBarcodes

Removes all the DSDecodedBarcodeElement from the DSDecodedBarcodesUnit.

• Objective-C
• Swift

1. - (void)removeAllDecodedBarcodes
   

2. func removeAllDecodedBarcodes()
   

setDecodedBarcode

Set the DSDecodedBarcodeElement of the DSDecodedBarcodesUnit.

• Objective-C
• Swift

1. - (NSInteger)setDecodedBarcode:(DSDecodedBarcodeElement*)element
        matrixToOriginalImage:(CGAffineTransform)matrixToOriginalImage
   

2. func setDecodedBarcode(element: DSDecodedBarcodeElement, matrixToOriginalImage: CGAffineTransform) -> Int
   

Parameters

[in] element: The DSDecodedBarcodeElement to replace all the decoded barcodes of the DSDecodedBarcodesUnit.

[in] matrixToOriginalImage: The transformation matrix to convert the decoded barcode object to the original image.

Return Value

Returns the ErrorCode if it fails. Otherwise, returns 0.
