Rendering a document to JPG or PNG format is a straightforward process with GroupDocs.Viewer for .NET. Below is a step-by-step guide to help you achieve this:

Step 1: Define Output Directory

First, define the directory where you want the rendered pages to be saved. This directory should exist and be accessible by the application.

string outputDirectory = "Your Document Directory";

Step 2: Define Page File Path Format

Specify the format for the file paths of each rendered page. GroupDocs.Viewer will replace {0} with the page number while saving the files.

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

Step 3: Instantiate Viewer Object

Create an instance of the Viewer class by providing the path to the document file you want to render.

using (Viewer viewer = new Viewer("Path_to_Your_Document"))
{
    // Code for rendering goes here
}

Step 4: Define Rendering Options

Specify the rendering options according to your requirements. For JPG/PNG rendering, you’ll use JpgViewOptions or PngViewOptions.

JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);

Step 5: Render Document

Invoke the View method of the Viewer object and pass the rendering options created earlier.

viewer.View(options);

Step 6: Output Results

Once the rendering process is complete, you can inform the user about the successful rendering and provide the directory where the rendered pages are saved.

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