Support for DGN V7 in Aspose.CAD for .NET

Introduction

In the realm of .NET development, Aspose.CAD stands out as a powerful library for handling Computer-Aided Design (CAD) files. This tutorial delves into a specific feature of Aspose.CAD for .NET—support for DGN V7 files. DGN, short for Design, is a widely used file format in the CAD domain. Aspose.CAD simplifies the process of working with DGN V7 files, offering developers a seamless experience.

Prerequisites

Before we dive into the implementation, ensure you have the following prerequisites in place:

• Aspose.CAD for .NET: Make sure you have the Aspose.CAD library installed. You can download it from the website.

• Development Environment: Set up a working .NET development environment, including Visual Studio or any other preferred IDE.

Now that we have the prerequisites sorted, let’s explore how to leverage the support for DGN V7 in Aspose.CAD for .NET.

Import Namespaces

Start by importing the necessary namespaces to access the functionality of Aspose.CAD:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.CAD;

Step 1: Load DGN File

Begin by loading an existing DGN file as a CadImage. Replace "Your Document Directory" and "Nikon_D90_Camera.dgn" with the appropriate directory path and file name.

string MyDir = "Your Document Directory";
string sourceFilePath = MyDir + "Nikon_D90_Camera.dgn";

using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath))
{
    // Code for further steps goes here...
}

Step 2: Configure Rasterization Options

Create a CadRasterizationOptions object to define and set various properties related to rasterization.

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions
{
    PageWidth = 600,
    PageHeight = 300,
    NoScaling = true,
    AutomaticLayoutsScaling = false
};

Step 3: Set Vector Rasterization Options

Create a JpegOptions object as we intend to convert the DGN file to JPEG. Assign the previously created CadRasterizationOptions object to it.

ImageOptionsBase options = new JpegOptions
{
    VectorRasterizationOptions = rasterizationOptions
};

Step 4: Save the Rasterized Image

Call the Save method of the CadImage class object to export the DGN file to a raster image, in this case, a JPEG.

cadImage.Save(MyDir + "ExportDGNToRasterImage_out.jpeg", options);

With these steps completed, the DGN file is successfully exported to a raster image.

Conclusion

In this tutorial, we explored the seamless support for DGN V7 in Aspose.CAD for .NET. By following the step-by-step guide, developers can effortlessly convert DGN files to raster images, expanding the capabilities of their .NET applications.
