Timeout on Save for CAD with Aspose.CAD

Introduction

Welcome to the tutorial on putting a timeout on save using Aspose.CAD for Java. In this guide, we’ll walk you through the process of setting a timeout for saving CAD drawings to enhance your application’s performance. Aspose.CAD for Java is a powerful library that allows you to work with CAD files in your Java applications seamlessly.

Prerequisites

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

• Aspose.CAD for Java Library: Ensure that you have the Aspose.CAD for Java library integrated into your project. You can download the library from the website.
• Development Environment: Set up your Java development environment with all the necessary tools and dependencies.

Import Packages

To get started, import the required packages into your Java project. Add the following lines at the beginning of your Java file:

import com.aspose.cad.Image;
import com.aspose.cad.InterruptionTokenSource;
import com.aspose.cad.fileformats.cad.CadImage;
import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PdfOptions;
import java.util.concurrent.TimeUnit;

Now, let’s break down the example code into step-by-step instructions:

Step 1: Set Source and Output Directories

final String SourceDir = Utils.getDataDir_DWGDrawings();
final String OutputDir = Utils.getDataDir_Output();

Ensure you have the correct source and output directories for your CAD drawings.

Step 2: Create Interruption Token Source

final InterruptionTokenSource source = new com.aspose.cad.InterruptionTokenSource();

Initialize an interruption token source to manage interruptions during the save operation.

Step 3: Load CAD Drawing

final CadImage cadImageBig = (CadImage)Image.load(SourceDir + "Drawing11.dwg");

Load the CAD drawing into a CadImage object.

Step 4: Configure Rasterization Options

CadRasterizationOptions rasterizationOptionsBig = new CadRasterizationOptions();
rasterizationOptionsBig.setPageWidth(cadImageBig.getSize().getWidth() / 2);
rasterizationOptionsBig.setPageHeight(cadImageBig.getSize().getHeight() / 2);

Configure rasterization options for the CAD drawing.

Step 5: Configure PDF Options

final PdfOptions CADfBig = new PdfOptions();
CADfBig.setVectorRasterizationOptions(rasterizationOptionsBig);
CADfBig.setInterruptionToken(source.getToken());

Set up PDF options with vector rasterization options and the interruption token.

Step 6: Save Drawing with Timeout

cadImageBig.save(OutputDir + "PutTimeoutOnSave_out.pdf", CADfBig);

Save the CAD drawing to a PDF file with the specified timeout.

Step 7: Handle Interruption

java.lang.Thread thread = new java.lang.Thread(new Runnable() {
    @Override
    public void run() {
        try {
            cadImageBig.save(OutputDir + "PutTimeoutOnSave_out.pdf", CADfBig);
        } catch (Throwable th) {
            System.out.println("interrupted !!!");
        }
    }
});
thread.start();
TimeUnit.SECONDS.sleep(3);
source.interrupt();
thread.join();

Create a thread to handle the save operation and interrupt it after a specified timeout.

Conclusion

Congratulations! You have successfully learned how to put a timeout on save using Aspose.CAD for Java. This feature can greatly enhance the efficiency of your CAD-related applications.
