## DataMatrixExtendedParameters class

Stores special data of DataMatrix recognized barcode This sample shows how to get DataMatrix raw values let generator = new BarcodeGenerator(EncodeTypes.DATA_MATRIX, "12345")) generator.save("test.png", BarcodeImageFormat.PNG); let reader = new BarCodeReader("test.png", null, DecodeType.DATA_MATRIX)) let results = reader.readBarCodes(); for(let i = 0; i < results.length; i++) { let result = results[i]; console.log("BarCode type: " + result.getCodeTypeName()); console.log("BarCode codetext: " + result.getCodeText()); console.log("DataMatrix barcode ID: " + result.getExtended().getDataMatrix().getStructuredAppendBarcodeId()); console.log("DataMatrix barcodes count: " + result.getExtended().getDataMatrix().getStructuredAppendBarcodesCount()); console.log("DataMatrix file ID: " + result.getExtended().getDataMatrix().getStructuredAppendFileId()); console.log("DataMatrix is reader programming: " + result.getExtended().getDataMatrix().isReaderProgramming()); }

```js
new DataMatrixExtendedParameters()
```

### equals(obj) {#equals}

Returns a value indicating whether this instance is equal to a specified `DataMatrixExtendedParameters` value.

| Parameter | Description |
| --- | --- |
| obj | An System.Object value to compare to this instance. |

**Returns:** `true ` if obj has the same value as this instance; otherwise, `false `.

### getStructuredAppendBarcodeId() {#getstructuredappendbarcodeid}
