This code explains concept. it works on my localmachine, you will have to add code to delete file and proper error handling.

<%@ Page Language="C#" %>


<%@ import Namespace="System.Diagnostics" %>


<script runat="server">


    string url="http://www.google.com";


    void Page_Load(object sender, EventArgs e) {





                if(Request.Params["weburl"] != null){


                     url = Request.Params["weburl"];


                }


                string savepath = String.Format("C:\\IECapt\\{0}.png" , System.Guid.NewGuid());





                System.Diagnostics.Process process = new System.Diagnostics.Process();


                process.StartInfo.FileName  = "C:\\IECapt\\IECapt.exe";


	process.StartInfo.Arguments = String.Format("\"{0}\" \"{1}\"",url,savepath);


	process.StartInfo.UseShellExecute = false;


	process.Start();


	process.WaitForExit();


	process.Dispose();


	Response.Clear();


	Response.ContentType = "image/png";


	Response.WriteFile(savepath);


	Response.End();


    }

How do i capture a web page as an image file?

kingpoop — Mon, 20 Dec 2004 19:36:44 GMT

Hello All,
I am trying to render HTML output of a .aspx page into an image file.

For example: If I have a web page named WebForm1.aspx, then I would like
to capture the output as a .jpeg file.

There exists a utility on located on sourceforge.net:
IECapt - A Internet Explorer Web Page Rendering Capture Utility
http://iecapt.sourceforge.net/

and, I would like for my code to be able to perform the same function as this
utility, however, this utility is an .exe and I have to Shell out of my
aspx code and open a new process to run it as follows:

using System.Diagnostics; 





Process myProcess = new Process(); 


myProcess.EnableRaisingEvents = False ; 


myProcess.StartInfo.RedirectStandardOutput = False; 


myProcess.StartInfo.UseShellExecute = False; 


myProcess.StartInfo.WorkingDirectory = "C:\Inetpub\wwwroot\TXWB\Forms"; 


myProcess.StartInfo.FileName = "C:\Inetpub\wwwroot\TXWB\Forms\IECapt.exe"; 


myProcess.StartInfo.Arguments = _ 


"http://localhost/TXWB/Forms/39610Confirm.aspx?objPATNO=186031" + "c:\test.jpeg"; 


myProcess.Start(); 


myProcess.WaitForExit(); 


myProcess.Dispose();

The resulting output I get by running the above is an image file of the target
.aspx page after it has rendered through the IE rendering engine. The problem
is I just can't figure out how to accomplish this same task within the .net
framework with existing .net assemblies.

I tried using the System.Net.WebClient assembly and am able to fetch the
target .aspx page in a string variable as follows:

using System.Text; 


using System.Net; 





string imageString; 


string URLToLoad; 


URLToLoad = "http://localhost/TXWB/Forms/39610Confirm.aspx?objPATNO=186031"; 


ASCIIEncoding encASCIIEncoding = new ASCIIEncoding(); 


WebClient wbcWebClient = new WebClient(); 


imageString = encASCIIEncoding.GetString(wbcWebClient.DownloadData(URLToLoad));

The imageString variable contains the HMTL markup of the target page, however, I
don't know how to render this HTML through the IE rendering engine to save it as
an image file.

I tried to covert the source code for the IECapt utility, but it uses the
Active Template Library, and I don't know if it's possible to convert.
Here is the source code:
http://cvs.sourceforge.net/viewcvs.py/iecapt/IECapt/IECapt/IECapt.cpp

If you have any input you could provide, I am greatful for your thoughts.
Thank you so much for take the time to read and reply and I greatly appreciate any suggestions.
