Convert PostScript to PDF in Java

Introduction

In the world of Java development, converting PostScript files to PDF is a common requirement. Aspose.Page for Java provides a robust solution for this task, offering developers a seamless experience in handling PostScript documents and transforming them into PDF format.

Prerequisites

Before diving into the tutorial, ensure that you have the following prerequisites in place:

• Java Development Kit (JDK): As this tutorial involves Java programming, make sure you have the latest JDK installed on your system.
• Aspose.Page for Java Library: You’ll need to download and include the Aspose.Page library in your Java project. You can find the library here.

Import Packages

To get started, import the necessary packages into your Java project. These packages are essential for interacting with PostScript files and handling the conversion process.

import com.aspose.eps.PsDocument;
import com.aspose.eps.device.PdfSaveOptions;
import com.aspose.page.License;

import java.io.FileInputStream;
import java.io.FileOutputStream;

Step 1: Set Up Your Development Environment

Before you start coding, ensure that you have a working Java development environment. Install the latest JDK, and set up your preferred Integrated Development Environment (IDE).

Step 2: Download and Include Aspose.Page Library

Visit the Aspose.Page for Java download page and download the latest version of the library. Once downloaded, include it in your Java project by adding the JAR file to your classpath.

Step 3: Create a Java Class

Create a new Java class in your project to house the conversion logic. You can name it something like PostScriptToPdfConverter.

Step 4: Import Aspose.Page Packages

In your Java class, import the necessary Aspose.Page packages to use the functionalities required for handling PostScript files.

import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.aspose.eps.PsDocument;
import com.aspose.eps.saveoptions.PdfSaveOptions;

Step 5: Initialize Input and Output Streams

Set up input and output streams to handle the PostScript input file and PDF output file.

String dataDir = "Your Document Directory";
FileOutputStream pdfStream = new FileOutputStream(dataDir + "PStoPDF.pdf");
FileInputStream psStream = new FileInputStream(dataDir + "input.ps");

Step 6: Load the PostScript Document

Use Aspose.Page to load the PostScript document from the input stream.

PsDocument document = new PsDocument(psStream);

Step 7: Set Conversion Options

Configure the conversion options, such as suppressing minor errors during the conversion process.

boolean suppressErrors = true;
PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
// Add additional fonts folders if needed
//options.setAdditionalFontsFolders(new String[] {"FONTS_FOLDER"});

Step 8: Initialize PDF Device

Initialize the PDF device for the conversion process.

com.aspose.eps.device.PdfDevice device = new com.aspose.eps.device.PdfDevice(pdfStream);
// Specify page size and image format if needed
//com.aspose.eps.device.PdfDevice device = new com.aspose.eps.device.PdfDevice(pdfStream, new Dimension(595, 842));

Step 9: Perform the Conversion

Execute the conversion process and save the PDF document.

try {
    document.save(device, options);
} finally {
    psStream.close();
    pdfStream.close();
}

Step 10: Review Errors (Optional)

If you chose to suppress errors during the conversion, you can review any exceptions that occurred.

if (suppressErrors) {
    for (Exception ex : options.getExceptions()) {
        System.out.println(ex.getMessage());
    }
}

Now you have successfully converted a PostScript file to PDF using Aspose.Page for Java. Experiment with different options and integrate this functionality into your Java applications effortlessly.
