Render FODG and ODG Images

Introduction

In the world of software development, efficient handling of document formats is paramount. GroupDocs.Viewer for .NET is a powerful tool designed to simplify the process of rendering FODG and ODG images within .NET applications. This tutorial will walk you through the steps required to render these images into various formats, such as HTML, JPG, PNG, and PDF, using GroupDocs.Viewer for .NET.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites:

1. GroupDocs.Viewer for .NET: Download and install GroupDocs.Viewer for .NET from here.
2. .NET Framework: Make sure you have .NET Framework installed on your system.
3. Basic knowledge of C#: Familiarity with C# programming language will be helpful.

Import Namespaces

Before starting with the implementation, import the necessary namespaces:

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

Step 1: Set Output Directory

string outputDirectory = "Your Document Directory";

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

Step 2: Render to HTML

string pageFilePathFormat = Path.Combine(outputDirectory, "fodg_result.html");
using (Viewer viewer = new Viewer(TestFiles.SAMPLE_FODG))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    viewer.View(options);
}

This step renders the FODG image to HTML format.

Step 3: Render to JPG

pageFilePathFormat = Path.Combine(outputDirectory, "fodg_result.jpg");
using (Viewer viewer = new Viewer(TestFiles.SAMPLE_FODG))
{
    JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);
    viewer.View(options);
}

Here, the FODG image is rendered to JPG format.

Step 4: Render to PNG

pageFilePathFormat = Path.Combine(outputDirectory, "fodg_result.png");
using (Viewer viewer = new Viewer(TestFiles.SAMPLE_FODG))
{
    PngViewOptions options = new PngViewOptions(pageFilePathFormat);
    viewer.View(options);
}

This step converts the FODG image to PNG format.

Step 5: Render to PDF

pageFilePathFormat = Path.Combine(outputDirectory, "fodg_result.pdf");
using (Viewer viewer = new Viewer(TestFiles.SAMPLE_FODG))
{
    PdfViewOptions options = new PdfViewOptions(pageFilePathFormat);
    viewer.View(options);
}

Finally, the FODG image is rendered to PDF format.
