In today’s digital age, document rendering plays a crucial role in various applications. Whether it’s displaying documents on a website or converting them into different formats, efficient rendering is essential. GroupDocs.Viewer for .NET provides a robust solution for viewing and manipulating documents within .NET applications. In this tutorial, we’ll delve into rendering Visio figures using GroupDocs.Viewer for .NET, breaking down the process into simple steps.

Prerequisites

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

  1. Environment Setup: Make sure you have a working environment for .NET development.
  2. GroupDocs.Viewer for .NET: Download and install GroupDocs.Viewer for .NET from the download link.
  3. Basic Understanding of C#: Familiarize yourself with C# programming language fundamentals.
  4. Sample Visio Document: Have a sample Visio document ready for rendering.

Import Namespaces

In your C# project, start by importing the necessary namespaces:

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

1. Rendering to HTML

string outputDirectory = "Your Document Directory";
string pageFilePathFormat = Path.Combine(outputDirectory, "result_page.html");
using (Viewer viewer = new Viewer("YourVisioDocumentPath"))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    options.VisioRenderingOptions.RenderFiguresOnly = true;
    options.VisioRenderingOptions.FigureWidth = 250;
    viewer.View(options);
}
  • Output Directory: Define the directory where the rendered HTML will be saved.
  • Page File Path Format: Specify the path format for the HTML page.
  • Viewer Initialization: Initialize the Viewer object with the path to the Visio document.
  • HTML View Options: Configure options for rendering HTML.
  • Visio Rendering Options: Set options specific to Visio rendering, such as rendering only figures and figure width.

2. Rendering to JPG

string pageFilePathFormat = Path.Combine(outputDirectory, "visio_result.jpg");
using (Viewer viewer = new Viewer("YourVisioDocumentPath"))
{
    JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);
    options.VisioRenderingOptions.RenderFiguresOnly = true;
    options.VisioRenderingOptions.FigureWidth = 250;
    viewer.View(options);
}
  • Similar to rendering to HTML, configure options for rendering to JPG format.

3. Rendering to PNG

string pageFilePathFormat = Path.Combine(outputDirectory, "visio_result.png");
using (Viewer viewer = new Viewer("YourVisioDocumentPath"))
{
    PngViewOptions options = new PngViewOptions(pageFilePathFormat);
    options.VisioRenderingOptions.RenderFiguresOnly = true;
    options.VisioRenderingOptions.FigureWidth = 250;
    viewer.View(options);
}
  • Configuration for rendering to PNG format follows a similar pattern as JPG rendering.

4. Rendering to PDF

string pageFilePathFormat = Path.Combine(outputDirectory, "visio_result.pdf");
using (Viewer viewer = new Viewer("YourVisioDocumentPath"))
{
    PdfViewOptions options = new PdfViewOptions(pageFilePathFormat);
    options.VisioRenderingOptions.RenderFiguresOnly = true;
    options.VisioRenderingOptions.FigureWidth = 250;
    viewer.View(options);
}
  • For rendering to PDF, configure options specific to PDF format.
