## QrExtCodetextBuilder class




```cpp
class QrExtCodetextBuilder : public Aspose::BarCode::Generation::ExtCodetextBuilder
```

## Methods

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


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

Use TwoDDisplayText property of [BarcodeGenerator](../barcodegenerator/) to set visible text to removing managing characters.

This sample shows how to use FNC1 first position in Extended Mode. 
```cpp
[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. 
```cpp
[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. 
```cpp
[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");
}
```
