IronBarcode 是否支持 GS1 UCC/EAN-128 符号？

具 GS1 條碼可被準確識別和解碼。然而，目前問題在於顯示的條碼值缺乏括號。

當使用 GS1-128 時，IronBarcode 目前輸出：01950123456789033103000123（識別為帶有 GS1 簽名的 Code 128 條碼）。希望在圖像輸出中顯示的值為：01950123456789033103000123。然而，條碼掃描器會輸出 (01)95012345678903(3103)000123 並檢測條碼類型為 Code128。

要生成 GS1-128 條碼，請使用以下代碼：

using IronBarCode;

class BarcodeExample
{
    static void Main()
    {
        // Create a GS1-128 barcode using the specified value
        GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("01950123456789033103000123", BarcodeWriterEncoding.Code128GS1);

        // Add the barcode value text below the barcode on the generated image
        barcode.AddBarcodeValueTextBelowBarcode();

        // Save the barcode image as a PNG file
        barcode.SaveAsPng("gs1code128.png");
    }
}

using IronBarCode;

class BarcodeExample
{
    static void Main()
    {
        // Create a GS1-128 barcode using the specified value
        GeneratedBarcode barcode = BarcodeWriter.CreateBarcode("01950123456789033103000123", BarcodeWriterEncoding.Code128GS1);

        // Add the barcode value text below the barcode on the generated image
        barcode.AddBarcodeValueTextBelowBarcode();

        // Save the barcode image as a PNG file
        barcode.SaveAsPng("gs1code128.png");
    }
}

Imports IronBarCode

Friend Class BarcodeExample
	Shared Sub Main()
		' Create a GS1-128 barcode using the specified value
		Dim barcode As GeneratedBarcode = BarcodeWriter.CreateBarcode("01950123456789033103000123", BarcodeWriterEncoding.Code128GS1)

		' Add the barcode value text below the barcode on the generated image
		barcode.AddBarcodeValueTextBelowBarcode()

		' Save the barcode image as a PNG file
		barcode.SaveAsPng("gs1code128.png")
	End Sub
End Class

輸出條碼

輸出條碼範例

上述代碼會生成帶有預設分隔符的 GS1-128 條碼。若要添加額外的分隔符，您可以插入 Unicode 分隔符 \u00f1。然而，請注意，使用 AddBarcodeValueTextBelowBarcode 方法時，將顯示 Unicode 字元 ñ（代碼 0x00F1）。為了克服此限制，可藉由操作字串並傳遞修改後的值給 AddAnnotationTextBelowBarcode 方法作為替代方案。這樣，您可以在沒有 ñ 字元的情況下實現希望的條碼值顯示。

using IronBarCode;

class BarcodeExampleWithAnnotation
{
    static void Main()
    {
        // Original barcode value
        string barcodeValue = "0195012345678903310300012300\u00f10000000123300000\u00f10000012312300000";

        // Remove unwanted unicode characters for display purposes
        string trimmedString = barcodeValue.Replace("\u00f1", "");

        // Create a GS1-128 barcode using the original value
        GeneratedBarcode barcode = BarcodeWriter.CreateBarcode(barcodeValue, BarcodeWriterEncoding.Code128GS1);

        // Add a custom annotation text below the barcode with the trimmed value
        barcode.AddAnnotationTextBelowBarcode(trimmedString);

        // Save the barcode image as a PNG file
        barcode.SaveAsPng("gs1code128.png");
    }
}

using IronBarCode;

class BarcodeExampleWithAnnotation
{
    static void Main()
    {

        string barcodeValue = "0195012345678903310300012300\u00f10000000123300000\u00f10000012312300000";

        // Remove unwanted unicode characters for display purposes
        string trimmedString = barcodeValue.Replace("\u00f1", "");

        // Create a GS1-128 barcode using the original value
        GeneratedBarcode barcode = BarcodeWriter.CreateBarcode(barcodeValue, BarcodeWriterEncoding.Code128GS1);

        // Add a custom annotation text below the barcode with the trimmed value
        barcode.AddAnnotationTextBelowBarcode(trimmedString);

        // Save the barcode image as a PNG file
        barcode.SaveAsPng("gs1code128.png");
    }
}
