Render EMZ and EMF Images

Introduction

GroupDocs.Viewer for .NET is a powerful document rendering API that allows developers to display various document types, including EMZ (Enhanced Windows Metafile) and EMF (Enhanced Metafile) images, in their .NET applications. In this tutorial, we will explore how to render EMZ and EMF images to different formats such as HTML, JPG, PNG, and PDF using GroupDocs.Viewer for .NET.

Prerequisites

Before we begin, make sure you have the following prerequisites:

  1. GroupDocs.Viewer for .NET: You can download the library from here.
  2. Development Environment: Ensure you have a compatible development environment set up for .NET development.
  3. Sample EMZ/EMF Images: Have sample EMZ and EMF images available for rendering.

Import Namespaces

Before diving into the code, let’s import the necessary namespaces:

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

Now, let’s break down each example into multiple steps in a step-by-step guide format:

Rendering EMZ/EMF Images to HTML

Step 1: Set Output Directory:

string outputDirectory = "Your Document Directory";

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

Step 2: Define Page File Path Format:

string pageFilePathFormat = Path.Combine(outputDirectory, "emz_result.html");

This will specify the file path format for the rendered HTML file.

Step 3: Render to HTML:

using (Viewer viewer = new Viewer(TestFiles.SAMPLE_EMZ))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    
    viewer.View(options);
}

This code initializes the Viewer object with the sample EMZ image and renders it to HTML format using specified options.

Rendering EMZ/EMF Images to JPG, PNG, and PDF

Repeat the following steps for rendering to JPG, PNG, and PDF formats:

Step 1: Define Page File Path Format:

pageFilePathFormat = Path.Combine(outputDirectory, "emz_result.jpg");

Adjust the file name and extension according to the desired output format (jpg, png, or pdf).

Step 2: Render to Respective Format:

using (Viewer viewer = new Viewer(TestFiles.SAMPLE_EMZ))
{
    // Adjust options according to the output format (Jpg, Png, Pdf)
    JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);
    
    viewer.View(options);
}

Replace JpgViewOptions with PngViewOptions or PdfViewOptions based on the desired output format.
