Export CAD Layouts to PDF with Aspose.CAD for Java

Introduction

In the ever-evolving field of computer-aided design (CAD), Aspose.CAD for Java stands out as a powerful tool for manipulating and converting CAD files. In this tutorial, we will guide you through the process of exporting CAD layouts to PDF using Aspose.CAD for Java. Whether you’re a seasoned developer or just diving into the world of CAD, this step-by-step guide will help you harness the full potential of this versatile Java library.

Prerequisites

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

• Aspose.CAD for Java: Ensure that you have the library installed. You can download it from the Aspose website here.

• Java Development Environment: Make sure you have a Java development environment set up on your machine.

Now that you have everything set up, let’s get started with the tutorial.

Import Namespaces

In your Java code, start by importing the necessary namespaces. These imports provide access to the classes and methods needed for working with Aspose.CAD for Java.

import com.aspose.cad.Image;
import com.aspose.cad.InterpolationMode;
import com.aspose.cad.SmoothingMode;
import com.aspose.cad.TextRenderingHint;

import com.aspose.cad.imageoptions.CadRasterizationOptions;
import com.aspose.cad.imageoptions.PdfOptions;
//import com.aspose.cad.imageoptions.TypeOfEntities;

Step 1: Load the CAD File

Begin by loading the CAD file into your Java application using the Image.load method. Replace "conic_pyramid.dxf" with the path to your CAD file.

String dataDir = "Your Document Directory" + "ExportingCAD/";
String srcFile = dataDir + "conic_pyramid.dxf";
Image cadImage = Image.load(srcFile);

Step 2: Set Rasterization Options

Create an instance of CadRasterizationOptions to define how the CAD entities should be rasterized. Adjust parameters such as page width, page height, and layout scaling according to your requirements.

CadRasterizationOptions rasterizationOptions = new CadRasterizationOptions();
rasterizationOptions.setPageWidth(1600);
rasterizationOptions.setPageHeight(1600);
rasterizationOptions.setAutomaticLayoutsScaling(true);
rasterizationOptions.setNoScaling(false);
rasterizationOptions.setContentAsBitmap(true);
rasterizationOptions.setLayouts(new String[]{"Model"});

Step 3: Set PDF Options

Create an instance of PdfOptions and associate it with the rasterization options. Additionally, set graphics options for the PDF export, such as smoothing mode, text rendering hint, and interpolation mode.

PdfOptions pdfOptions = new PdfOptions();
pdfOptions.setVectorRasterizationOptions(rasterizationOptions);
rasterizationOptions.getGraphicsOptions().setSmoothingMode(SmoothingMode.HighQuality);
rasterizationOptions.getGraphicsOptions().setTextRenderingHint(TextRenderingHint.AntiAliasGridFit);
rasterizationOptions.getGraphicsOptions().setInterpolationMode(InterpolationMode.HighQualityBicubic);

Step 4: Export to PDF

Finally, export the CAD layouts to a PDF file using the save method of the cadImage object.

cadImage.save(dataDir + "CADLayoutsToPDF_out_.pdf", pdfOptions);

Congratulations! You have successfully exported CAD layouts to PDF using Aspose.CAD for Java. Feel free to explore additional features and functionalities offered by Aspose.CAD to enhance your CAD file manipulation experience.
