• Aspose.CAD for Java: Download and install Aspose.CAD for Java library from here.

Import Packages

To get started, you need to import the necessary packages in your Java project. Add the following import statements to your code:

import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.OutputStream;
import com.aspose.cad.Image;
import com.aspose.cad.ImageOptionsBase;
import com.aspose.cad.fileformats.cad.CadImage;
import com.aspose.cad.fileformats.dgn.DgnImage;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.JpegOptions;
import com.aspose.cad.imageoptions.PdfOptions;

Now, let’s break down the example code into multiple steps:

Step 1: Set Up Input and Output Paths

Define the directory path where your document is located and specify the input DWG file name.

String dataDir = "Your Document Directory" + "ExportingDGN/";
String fileName = dataDir + "BlockRefDgn.dwg";

Step 2: Load DWG File

Load the DWG file into an Image object using Aspose.CAD.

Image objImage = Image.load(fileName);

Step 3: Configure Rasterization Options

Configure rasterization options, such as layouts to be included in the export.

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setLayouts(new String[] {"Model"});

Step 4: Configure PDF Options

Set up PDF options, including vector rasterization options.

PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);

Step 5: Save PDF File

Save the PDF file with the configured options.

objImage.save(dataDir + "BlockRefDgn.pdf", pdfOptions);

Conclusion

Congratulations! You’ve successfully exported an embedded DGN file to PDF using Aspose.CAD for Java. This tutorial covered the essential steps to integrate Aspose.CAD into your Java application for efficient CAD file manipulation.
