## QrExtCodetextBuilder class

Extended codetext generator for 2D QR barcodes for ExtendedCodetext Mode of EncodeMode

Use TwoDDisplayText property of BarcodeGenerator to set visible text to removing managing characters.

```csharp
public class QrExtCodetextBuilder : ExtCodetextBuilder
```

## Constructors

| Name | Description |
| --- | --- |
| [QrExtCodetextBuilder](qrextcodetextbuilder/)() | The default constructor. |

## Methods

| Name | Description |
| --- | --- |
| [AddCodetextWithCompactionMode](../../aspose.barcode.generation/qrextcodetextbuilder/addcodetextwithcompactionmode/)(QrExtCompactionMode, string) | Adds codetext with the specified QR compaction mode to the extended codetext items. |
| [AddECICodetext](../../aspose.barcode.generation/extcodetextbuilder/addecicodetext/)(ECIEncodings, string) | Adds codetext with Extended Channel Identifier |
| [AddFNC1FirstPosition](../../aspose.barcode.generation/qrextcodetextbuilder/addfnc1firstposition/)() | Sets FNC1 in first position. If another FNC1 mode was set before, it is replaced. |
| [AddFNC1GroupSeparator](../../aspose.barcode.generation/qrextcodetextbuilder/addfnc1groupseparator/)() | Adds Group Separator (GS - '\\u001D') to the extended codetext items |
| [AddFNC1SecondPosition](../../aspose.barcode.generation/qrextcodetextbuilder/addfnc1secondposition/)(string) | Sets FNC1 in second position. If another FNC1 mode was set before, it is replaced. |
| [AddPlainCodetext](../../aspose.barcode.generation/extcodetextbuilder/addplaincodetext/)(string) | Adds plain codetext to the extended codetext items |
| override [Clear](../../aspose.barcode.generation/qrextcodetextbuilder/clear/)() | Clears extended codetext items |
| override [GetExtendedCodetext](../../aspose.barcode.generation/qrextcodetextbuilder/getextendedcodetext/)() | Generates Extended codetext from the extended codetext list. |

## Examples

This sample shows how to use FNC1 first position in Extended Mode.

```csharp
[C#]
//create codetext
QrExtCodetextBuilder TextBuilder = new QrExtCodetextBuilder();
TextBuilder.AddFNC1FirstPosition();
TextBuilder.AddPlainCodetext("000%89%%0");
TextBuilder.AddFNC1GroupSeparator();
TextBuilder.AddPlainCodetext("12345<FNC1>");

//generate codetext
string codetext = TextBuilder.GetExtendedCodetext();

//generate
using(BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR))
{
    generator.Parameters.Barcode.QR.EncodeMode = QREncodeMode.ExtendedCodetext;
    generator.Parameters.Barcode.QR.ErrorLevel = QRErrorLevel.LevelL;
	generator.CodeText = codetext;
    generator.Parameters.Barcode.CodeTextParameters.TwoDDisplayText = "My Text";
	generator.Save("test.bmp");
}
```

This sample shows how to use FNC1 second position in Extended Mode.

```csharp
[C#]
//create codetext
QrExtCodetextBuilder TextBuilder = new QrExtCodetextBuilder();
TextBuilder.AddFNC1SecondPosition("12");
TextBuilder.AddPlainCodetext("TRUE3456"); 

//generate codetext
string codetext = TextBuilder.GetExtendedCodetext();

//generate
using(BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR))
{
    generator.Parameters.Barcode.QR.EncodeMode = QREncodeMode.ExtendedCodetext;
    generator.Parameters.Barcode.QR.ErrorLevel = QRErrorLevel.LevelL;
	generator.CodeText = codetext;
    generator.Parameters.Barcode.CodeTextParameters.TwoDDisplayText = "My Text";
	generator.Save("test.bmp");
}
```

This sample shows how to use multi ECI mode in Extended Mode.

```csharp
[C#]
//create codetext
QrExtCodetextBuilder TextBuilder = new QrExtCodetextBuilder();
TextBuilder.AddECICodetext(ECIEncodings.Win1251, "Will");
TextBuilder.AddECICodetext(ECIEncodings.UTF8, "Right");
TextBuilder.AddECICodetext(ECIEncodings.UTF16BE, "Power");
TextBuilder.AddPlainCodetext(@"t\e\\st");
TextBuilder.AddCodetextWithCompactionMode(QrExtCompactionMode.AlphaNumeric, @"ASPOSE2001");
TextBuilder.AddCodetextWithCompactionMode(QrExtCompactionMode.Numeric, @"20012026");

//generate codetext
string codetext = TextBuilder.GetExtendedCodetext();

//generate
using(BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR))
{
    generator.Parameters.Barcode.QR.EncodeMode = QREncodeMode.ExtendedCodetext;
    generator.Parameters.Barcode.QR.ErrorLevel = QRErrorLevel.LevelL;
	generator.CodeText = codetext;
    generator.Parameters.Barcode.CodeTextParameters.TwoDDisplayText = "My Text";
	generator.Save("test.bmp");
}
```
