void Load(  
   String^ fileName 
)

def Load(self,fileName):

Parameters

fileName
The XML file containing the data.

To save and load data to an XML stream, use BarcodeReadOptions.Save(Stream stream) and BarcodeReadOptions.Load(Stream stream).

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeReadOptions_LoadSaveExample() 
{ 
   string xmlFileName = Path.Combine(LEAD_VARS.ImagesDir, "MyOptions.xml"); 
 
   // Create the options 
   OneDBarcodeReadOptions options1 = new OneDBarcodeReadOptions(); 
   // Show its values 
   ShowOptions("Default 1", options1); 
 
   // Change some of the values 
   options1.SearchDirection = BarcodeSearchDirection.HorizontalAndVertical; 
   options1.ReturnCheckDigit = BarcodeReturnCheckDigit.Default; 
   options1.EnableErrorCheck = true; 
   ShowOptions("New Options 1", options1); 
 
   // Save it to disk 
   options1.Save(xmlFileName); 
 
   // Create new options 
   OneDBarcodeReadOptions options2 = new OneDBarcodeReadOptions(); 
   // Show its values 
   ShowOptions("Default 2", options2); 
 
   // Load the previously saved options 
   options2.Load(xmlFileName); 
   // Show its values, should be the same as "New Options 1" 
   ShowOptions("Loaded 2", options2);
