Export DGN to Raster Image in Aspose.CAD for .NET

Introduction

In the dynamic realm of .NET development, Aspose.CAD emerges as a powerful tool for handling Computer-Aided Design (CAD) files. This tutorial dives into the process of exporting DGN files to raster images using Aspose.CAD for .NET. If you’re keen on transforming your DGN files into visually compelling raster images seamlessly, you’re in the right place.

Prerequisites

Before we embark on this journey, make sure you have the following prerequisites in place:

  • Aspose.CAD for .NET: Ensure you have the Aspose.CAD library installed in your .NET project. You can find the library and relevant documentation on the website.

  • Sample DGN File: Have a DGN file ready for conversion. In our example, we’ll use “Nikon_D90_Camera.dgn.”

Now, let’s dive into the step-by-step guide.

Import Namespaces

In your .NET project, begin by importing the necessary namespaces for Aspose.CAD. This step allows you to access the classes and methods required for DGN to raster image conversion.

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

Step 1: Load DGN File

Start by loading the DGN file into a CadImage object. This provides a foundation for subsequent operations.

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

using (CadImage cadImage = (CadImage)Image.Load(sourceFilePath))
{
    // Your code for further processing goes here
}

Step 2: Define Rasterization Options

Create a CadRasterizationOptions object and set various properties to customize the rasterization process according to your requirements.

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.PageWidth = 600;
rasterizationOptions.PageHeight = 300;
rasterizationOptions.NoScaling = true;
rasterizationOptions.AutomaticLayoutsScaling = false;

Step 3: Create JpegOptions Object

Since we aim to convert the DGN file to JPEG, create a JpegOptions object and assign the previously defined CadRasterizationOptions to it.

ImageOptionsBase options = new JpegOptions();
options.VectorRasterizationOptions = rasterizationOptions;

Step 4: Save the Raster Image

Utilize the Save method of the CadImage class to export the DGN file to a raster image in the desired format, in this case, a JPEG.

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

Conclusion

Congratulations! You’ve successfully navigated through the steps to export a DGN file to a raster image using Aspose.CAD for .NET. This tutorial has equipped you with the essential knowledge to integrate this functionality into your .NET projects effortlessly.
