Set Resource Loading Timeout (Advanced)

Introduction

In the realm of .NET development, GroupDocs.Viewer provides a powerful toolset for rendering documents and images with precision and efficiency. Leveraging its capabilities requires understanding its intricacies, including setting resource loading timeouts. In this tutorial, we’ll delve into the process of configuring resource loading timeouts in GroupDocs.Viewer for .NET.

Prerequisites

Before embarking on this tutorial, ensure you have the following prerequisites:

  1. Basic Knowledge of .NET Development: Familiarity with C# programming and .NET framework fundamentals is essential.
  2. Installation of GroupDocs.Viewer for .NET: Download and install GroupDocs.Viewer for .NET library from the download page.
  3. Integrated Development Environment (IDE): Have an IDE such as Visual Studio installed on your system.

Import Namespaces

Before diving into the coding process, import the necessary namespaces:

using System;
using System.IO;
using GroupDocs.Viewer.Options;

Step 1: Define Output Directory

Firstly, define the directory where the rendered documents will be saved:

string outputDirectory = "Your Document Directory";

Replace "Your Document Directory" with the path where you want to save the rendered documents.

Step 2: Define Page File Path Format

Define the format for the file paths of individual pages:

string pageFilePathFormat = Path.Combine(outputDirectory, "page_{0}.html");

This format will generate file names like page_1.html, page_2.html, etc., within the specified output directory.

Step 3: Configure Load Options

Configure the load options, including the resource loading timeout:

LoadOptions loadOptions = new LoadOptions
{
    ResourceLoadingTimeout = TimeSpan.FromSeconds(5)
};

In this example, a timeout of 5 seconds is set for resource loading.

Step 4: Initialize Viewer Object

Initialize the Viewer object with the document to be rendered and the defined load options:

using (Viewer viewer = new Viewer(TestFiles.WITH_EXTERNAL_IMAGE_DOC, loadOptions))

Replace TestFiles.WITH_EXTERNAL_IMAGE_DOC with the path to the document you want to render.

Step 5: Configure HTML View Options

Configure HTML view options for embedded resources:

HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);

This configuration ensures that embedded resources like images are included in the rendered HTML.

Step 6: Render Document

Render the document using the configured options:

viewer.View(options);

This step initiates the rendering process.

Step 7: Display Output Directory

Display a message indicating the successful rendering and the location of the output directory:

Console.WriteLine($"\nSource document rendered successfully.\nCheck output in {outputDirectory}.");

Conclusion

Mastering resource loading timeouts in GroupDocs.Viewer for .NET is crucial for ensuring smooth document rendering processes. By following this tutorial, you’ve gained insights into configuring timeouts effectively, enhancing your proficiency in .NET development.
