Prerequisites

Before diving into the tutorial, make sure you have the following prerequisites in place:

  • Java Development Kit (JDK) installed on your machine.
  • Aspose.CAD for Java library downloaded. You can get it here.
  • A valid license or a temporary license from here.

Import Namespaces

In your Java project, import the necessary namespaces:

import com.aspose.cad.Image;

import com.aspose.cad.fileformats.dgn.DgnImage;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.fileformats.cad.CadImage;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PngOptions;

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

Step 1: Set Up Your Project

Create a new Java project and add the Aspose.CAD for Java library to your project’s dependencies.

Step 2: Specify Your STL File

Define the path to your STL file. For example:

String dataDir = "Your Document Directory" + "ExportingSTL/";
String fileName = dataDir + "example.stl";

Step 3: Load STL File

Load the STL file using the Image.load method:

CadImage cadImage = (CadImage)Image.load(fileName);

Step 4: Configure Rasterization Options

Set up rasterization options for vectorization:

CadRasterizationOptions vectorOptions = new CadRasterizationOptions();
vectorOptions.setPageWidth(1500);
vectorOptions.setPageHeight(1500);

Step 5: Configure PNG Options

Specify options for PNG export:

PngOptions pngOptions = new PngOptions();
// Uncomment the line below if you want to set vector rasterization options
// pngOptions.setVectorRasterizationOptions(vectorOptions);

Step 6: Save as PNG

Save the CAD image as a PNG file:

String outPath = dataDir + "galeon.stl.png";
cadImage.save(outPath, pngOptions);

Congratulations! You’ve successfully exported an STL file to PNG using Aspose.CAD for Java.
