BarcodeOutputTextPosition Enumeration

Summary

The text position to use when the data string is written along with the barcode.

Syntax

Objective-C

C++/CLI

Java

Python

[SerializableAttribute()] 
public enum BarcodeOutputTextPosition

typedef NS_ENUM(NSInteger, LTBarcodeOutputTextPosition) { 
 LTBarcodeOutputTextPositionNone,  
 LTBarcodeOutputTextPositionDefault,  
 LTBarcodeOutputTextPositionTop 
};

public enum BarcodeOutputTextPosition

[SerializableAttribute()] 
public enum class BarcodeOutputTextPosition

class BarcodeOutputTextPosition(Enum): 
   None = 0 
   Default = 1 
   Top = 2

Members

Value	Member	Description
0	None	No text string in the output if supported by the symbology, otherwise, behaves as Default.
1	Default	Default text position as defined in the symbology standard, usually below the barcode. If no text output is supported by the symbology, behaves as None.
2	Top	Top of the barcode when supported by the symbology. Otherwise, behaves as Default.

Remarks

The BarcodeOutputTextPosition is used as the type of the following properties: OneDBarcodeWriteOptions.TextPosition and FourStateBarcodeWriteOptions.TextPosition.

These properties control whether the data string is written along with the barcode and if so, its position. Note that not all symbologies support all the position values. Some symbologies allow you to control the text position completely (none, default or top), while some will only let you specify whether the text is written or not but not the location (default or none). Other symbologies will always require the text to be written (default). Refer to the Barcode symbology standard you are interested in or try it with the C# Barcode demo. Writing the text with the barcode is supported only by 1D linear barcodes. The following 1D linear barcode symbologies do not support setting the barcode text string at the bottom (below the barcode) regardless of the value of OneDBarcodeWriteOptions.TextPosition:

Example

This example writes a UPC-A barcode using different text positions.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeWriteOptions_BarcodeOutputTextPositionExample() 
{ 
   BarcodeEngine barcodeEngine = new BarcodeEngine(); 
 
   // Create a directory to store the image we will create 
   string outDir = Path.Combine(LEAD_VARS.ImagesDir, "MyBarcodes"); 
   if (Directory.Exists(outDir)) 
   { 
      Directory.Delete(outDir, true); 
   } 
   Directory.CreateDirectory(outDir); 
 
   // Create an image to save to 
   using (RasterImage image = RasterImage.Create(2550, 3300, 24, 300, RasterColor.White)) 
   { 
      // Create the sample barcode data 
      BarcodeData data = new BarcodeData 
      { 
         Symbology = BarcodeSymbology.UPCA, 
         Value = "01234567890", 
         Bounds = new LeadRect(150, 150, 600, 200) 
      };

      OneDBarcodeWriteOptions options = new OneDBarcodeWriteOptions 
      { 
         EnableErrorCheck = true, 
         TextPosition = BarcodeOutputTextPosition.Top 
      }; 
 
      // Write the barcode 
      barcodeEngine.Writer.WriteBarcode(image, data, options); 
 
      // Create the output file 
      string outFileName = Path.Combine(outDir + ".tif"); 
 
      // Save the image 
      using (RasterCodecs codecs = new RasterCodecs()) 
         codecs.Save(image, outFileName, RasterImageFormat.Tif, 1); 
   }
