### getDecodedBarcodes

Returns all the barcodes that are decoded from the image as an array of [`DecodedBarcodeElement`](decoded-barcode-element.md).

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

```java
int getCount();
```

**Return Value**

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

```

**Parameters**

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

**Return Value**

A [`DecodedBarcodeElement`](decoded-barcode-element.md) representing the decoded barcode.

### removeAllDecodedBarcodes

void removeAllDecodedBarcodes();
```

### setDecodedBarcode

Set the [`DecodedBarcodeElement`](decoded-barcode-element.md) of the `DecodedBarcodesUnit`.

```java
int setDecodedBarcode(DecodedBarcodeElement element, Matrix matrixToOriginalImage);
```

**Parameters**

`decodedBarcode`: A `DecodedBarcodeElement` to replace all the decoded barcodes of the unit.

`matrixToOriginalImage`: The transformation matrix to convert the decoded barcode object to the original image.
