Summary

Gets or sets proxy information used with URI-based operations.

Syntax

C++/CLI

Python

public IWebProxy UriOperationProxy { get; set; }

public: 
property IWebProxy^ UriOperationProxy { 
   IWebProxy^ get(); 
   void set (    IWebProxy^ ); 
}

UriOperationProxy # get and set (RasterCodecs)

Property Value

The IWebProxy object to use to proxy URI-based operation. The default is a null reference.

Remarks

NOTE: This topic is part of RasterCodecs Async support using the .NET System.ComponentMode.AsyncOperation model. For .NET async/await support this type/member is not used. Instead, refer to RasterCodecs Async Operations.

The UriOperationProxy property identifies the WebProxy object to use to process requests to Internet resources.

To override the default proxy to use when accessing a remote resource, you must change the value of the UriOperationProxy property prior to calling any of these methods:

To change the authentication information to use when accessing a remote resource, use the UriOperationCredentials property.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg; 
 
 
public void SaveToSharePointExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // Change the path to a server you have access to 
   string mySharePointServer = @"http://leadweb3/Shared%20Documents"; 
 
   string myDocumentFileName = mySharePointServer + "/MyJpegFile.jpg"; 
 
   RasterImage image = null; 
 
   // Create a multi-page TIF file 
   for (int i = 0; i < 4; i++) 
   { 
      string pageFileName = Path.Combine(LEAD_VARS.ImagesDir, "Ocr" + (i + 1).ToString() + ".tif"); 
      RasterImage pageImage = codecs.Load(pageFileName, 0, CodecsLoadByteOrder.BgrOrGray, 1, 1); 
 
      if (image == null) 
         image = pageImage; 
      else 
      { 
         image.AddPage(pageImage); 
         pageImage.Dispose(); 
      } 
   } 
 
   // We have the image, upload it 
 
   // Use the credentials of the logged in user 
   // Change this if you have different user name/password/domain 
   // For example: 
   // codecs.UriOperationCredentials = new System.Net.NetworkCredential("myuser", "mypassword", "mydomain"); 
   codecs.UriOperationCredentials = System.Net.CredentialCache.DefaultCredentials; 
 
   // Use the default proxy 
   codecs.UriOperationProxy = WebRequest.DefaultWebProxy; 
 
   // Upload the second page of the file to the server as JPEG 
   codecs.Save(image, new Uri(myDocumentFileName), RasterImageFormat.Jpeg, 24, 2, 2); 
 
   image.Dispose(); 
 
   codecs.Dispose(); 
}
