Merge PostScript to PDF in Java

Introduction

In the realm of Java programming, efficient handling of document conversion is essential. One such crucial task is merging PostScript files into PDFs. Aspose.Page for Java provides a powerful solution for this task, offering developers a seamless experience. In this step-by-step guide, we will walk through the process of merging PostScript to PDF in Java using Aspose.Page.

Prerequisites

Before we dive into the tutorial, ensure you have the following prerequisites set up:

  • Aspose.Page for Java: Download and install the library from the Aspose.Page Java documentation.
  • Java Development Kit (JDK): Make sure you have JDK installed on your machine.
  • Integrated Development Environment (IDE): Choose an IDE of your preference, such as IntelliJ or Eclipse.

Import Packages

Start by importing the necessary packages to facilitate the merging 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: Import Required Packages

Begin by importing the necessary packages to work with Aspose.Page for Java.

import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.aspose.page.PsDocument;
import com.aspose.page.PdfSaveOptions;

Step 2: Set Document and Output Paths

Define the paths for your PostScript input file and the desired output PDF.

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

Step 3: Initialize PsDocument Object

Create a PsDocument object using the PostScript input stream.

PsDocument document = new PsDocument(psStream);

Step 4: Set Conversion Options

Configure options for the PDF conversion, including error suppression and additional font folders.

boolean suppressErrors = true;
PdfSaveOptions options = new PdfSaveOptions(suppressErrors);
// options.setAdditionalFontsFolders(new String[]{"FONTS_FOLDER"});

Step 5: Initialize PdfDevice

Create a PdfDevice object for handling the PDF output.

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

Step 6: Save Document to PDF

Save the PsDocument to PDF using the specified device and options.

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

Step 7: Review Errors

If error suppression is enabled, review any exceptions that occurred during the conversion.

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

Conclusion

In this tutorial, we explored the seamless process of merging PostScript files into PDFs using Aspose.Page for Java. By following the step-by-step guide, developers can efficiently handle document conversion tasks within their Java applications.
