RasterFault Class

Summary

The RasterFault class provides information about exceptions that occur on the client side.

Syntax

C++

[DataContractAttribute(Namespace="http://Leadtools.Services.Raster.FaultContracts/2009/01", Name="RasterFault")] 
public class RasterFault

  
<DataContractAttribute()> 
Public Class RasterFault

[DataContractAttribute()] 
public ref class RasterFault

Remarks

The RasterFault class defines an ErrorId and an ErrorMessage property that can be examined to determine the cause of an error.

Example

This example will show how to use RasterFault at the client side.

using Leadtools.Services; 
 
public void RasterFaultExample() 
{ 
   EffectsProcessingServiceClient client = new EffectsProcessingServiceClient(); 
 
   RawBinaryData sourceBinaryData = new RawBinaryData(); 
   sourceBinaryData.Data = File.ReadAllBytes(Path.Combine(LEAD_VARS.ImagesDir, "image1.cmp")); 
 
   RasterConvertOptions convertOptions = new RasterConvertOptions(); 
 
   convertOptions.Source = sourceBinaryData; 
   convertOptions.Destination = null; 
   convertOptions.Format = RasterImageFormat.Bmp; 
   convertOptions.FirstPage = 1; 
   convertOptions.LastPage = 1; 
   convertOptions.BitsPerPixel = 24; 
   convertOptions.QualityFactor = 2; 
 
   RawBinaryData destBinaryData = null; 
   CommandResponse response = null; 
   try 
   { 
      SharpenRequest request = new SharpenRequest(); 
 
      request.ConvertOptions = convertOptions; 
      request.RegionData = null; 
      request.Sharpness = 5000; 
 
      // pass invalid argument 
      response = client.Sharpen(request); 
   } 
   catch (FaultException ex) 
   { 
      Console.WriteLine(ex.Message);

   } 
 
   client.Close();
