Is there any way to export reporting as JPEG?

Is there any way to export my report as JPEG?

I'm used to designing my report by Telerik ASP.NET MVC report .

Hope to get some helps.

Hello Lemon,

The Image rendering extension supports JPEG rendering of the reports. You can use the rendering extension programmatically or you can configure the Image Device Information Settings OutputFormat so that the default export option in the report viewer will save the file as JPEG. Examples for configuring the device information settings in the application configuration file are available in the Extensions Element help article.

Hi,this is my configuration .

 

1.<Extension name="JPEG"
2.           description="JPEG File"
3.           type="Telerik.Reporting.ImageRendering.ImageReport, Telerik.Reporting, Version=9.1.15.624, Culture=neutral, PublicKeyToken=a9d7983dfcc261be">
4.  <Parameters>
5.    <Parameter name="OutputFormat" value="JPEG"></Parameter>
6.  </Parameters>
7.</Extension>

As I try to export , I got an exception .

Did ​I omit anything?

Hello Lemon,

You need to provide the parameter name and value for the IMAGE rendering extension:

<Telerik.Reporting>
  <Extensions>
    <Render>
      <Extension name="IMAGE" description="Image JPEG">
        <Parameters>
          <Parameter name="OutputFormat" value="JPEG"/>
        </Parameters>
      </Extension>
    </Render>
  </Extensions>
</Telerik.Reporting>

I changed my configuration like:

1.<Extension name="IMAGE" description="Image JPEG">
2. <Parameters>
3.  <Parameter name="OutputFormat" value="JPEG"/>
4. </Parameters>
5.</Extension>

 

but  I still get the same exception.

Hello Lemon,

In order to advise further, we will need to debug a runnable sample project exhibiting the issue. Please open a new support ticket where you can zip and attach the sample project.
