Class QrExtCodetextBuilder

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.

public class QrExtCodetextBuilder : ExtCodetextBuilder

Constructors

NameDescription
QrExtCodetextBuilder()The default constructor.

Methods

NameDescription
AddCodetextWithCompactionMode(QrExtCompactionMode, string)Adds codetext with the specified QR compaction mode to the extended codetext items.
AddECICodetext(ECIEncodings, string)Adds codetext with Extended Channel Identifier
AddFNC1FirstPosition()Sets FNC1 in first position. If another FNC1 mode was set before, it is replaced.
AddFNC1GroupSeparator()Adds Group Separator (GS - ‘\u001D’) to the extended codetext items
AddFNC1SecondPosition(string)Sets FNC1 in second position. If another FNC1 mode was set before, it is replaced.
AddPlainCodetext(string)Adds plain codetext to the extended codetext items
override Clear()Clears extended codetext items
override GetExtendedCodetext()Generates Extended codetext from the extended codetext list.

Examples

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

[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.

[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.

[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");
}
