Convert PDF to PS via Java
Java API to Export PDF to PostScript without using any third party application
Why Convert PDF Documents to PostScript (PS) via Java?
There are various reasons for converting a PDF file to PostScript. One reason is printing: some printers and print servers may not be compatible with PDF files, so converting them to PostScript can ensure that the file can be printed on any PostScript-compatible printer. In pre-press, PostScript files are often preferred because they provide more control over the layout and formatting of a document. Converting a PDF file to PostScript can make it easier to adjust the layout and formatting of a document before it goes to print. In some cases, there may be issues with a PDF file that make it difficult to print or view correctly. Converting the file to PostScript can help diagnose and troubleshoot any problems with the file. Additionally, PostScript files are often used for long-term archiving of printed documents, so converting a PDF file to PostScript can ensure that the document is preserved in a format that will be readable in the future.
How Aspose.Total can help in PDF to PS Conversion?
It is possible to convert PDF to PostScript by following two simple steps. The first step involves rendering the PDF file to DOC using a tool such as Aspose.PDF for Java. The second step is to use a powerful Document Processing API like Aspose.Words for Java to convert the DOC file to PS. Both of these APIs are available as part of the
Aspose.Total for Java
.
Aspose.PDF for Java is a reliable tool that allows for the rendering of PDF files to DOC format. This can be useful in situations where a PDF file needs to be converted to a format that is more easily editable or compatible with certain printers.Once the PDF file has been converted to DOC format, Aspose.Words for Java can be used to convert it to PostScript. Aspose.Words for Java is a powerful document processing API that allows for the conversion of various document formats to other formats such as PDF, HTML, and EPUB.
How to Convert PDF to PS via Java?
- Load PDF file using Aspose.PDF.Document class
- Convert PDF to DOC by using save method
- Load DOC file using Aspose.Words.Document class
- Save the document to PS format using save method and set PS as SaveFormat
Tools Required for PDF to PS Conversion
You can easily use Aspose.Total for Java directly from a Maven based project and include Aspose.PDF for Java and Aspose.Words for Java in your pom.xml.
Alternatively, you can get a ZIP file from downloads .
// load PDF file with an instance of Document class
Document document = new Document("template.pdf");
// save PDF as a DOC
document.save("DocOutput.doc", SaveFormat.DOC);
// load DOC with an instance of Document
Document outputDocument = new com.aspose.words.Document("DocOutput.doc");
// call save method while passing SaveFormat.PS
outputDocument.save("output.ps", SaveFormat.PS);
Open Password Protected PDF Document via Java
While converting PDF to PS, even if your document is password protected, you can still open it using PDF Manipulation API Aspose.PDF for Java . In order to open the encrypted file, you need to create a Document object and open the PDF using the owner’s password.
// open encrypted document
Document document = new Document("input.pdf", "password");
// save PDF as a DOC
document.save("DocOutput.doc", SaveFormat.DOC);
Save PS Document to Database as ByteArray via Java
While saving your input document to PS file format, you can also save your document to database instead of a file system. You may need to implement storing and retrieving Document objects to and from a database. This would be necessary if you were implementing any type of content management system. In order to save your PS to database it is often necessary to serialize the document to obtain a byte array. This can be done using Aspose.Words for Java API. After getting your byte array, you can store it in the database using SQL statement.
public static void StoreToDatabase(Document doc, Connection mConnection) throws Exception {
// create an output stream which uses byte array to save data
ByteArrayOutputStream aout = new ByteArrayOutputStream();
// save the document to byte array
doc.save(aout, SaveFormat.PS);
// get the byte array from output steam
// the byte array now contains the document
byte[] buffer = aout.toByteArray();
// get the filename from the document.
String fileName = doc.getOriginalFileName();
String filePath = fileName.replace("\\", "\\\\");
// create the SQL command.
String commandString = "INSERT INTO Documents (FileName, FileContent) VALUES('" + filePath + "', '" + buffer + "')";
Statement statement = mConnection.createStatement();
statement.executeUpdate(commandString);
}

What is PDF File Format?
PDF, or Portable Document Format, is a file format designed for presenting documents in a manner that remains consistent across various software applications, hardware devices, and operating systems. Each PDF file contains a comprehensive description of a fixed-layout document, encompassing text, fonts, graphics, and other necessary information for accurate display. Initially developed by Adobe Systems in the early 1990s, PDF served as a means to share computer documents while preserving text formatting and inline images.
PDF files are typically generated using software like Adobe Acrobat or similar PDF creation tools. Presently, PDF has become an open standard governed by the International Organization for Standardization (ISO). This standardization ensures compatibility and interoperability across different platforms and systems. To view PDF files, users can utilize free software such as Adobe Reader or other PDF viewers available.
One of the significant advantages of PDF is its platform independence, allowing seamless viewing and printing on a wide range of devices and operating systems. Regardless of the hardware or software used, the document’s layout and content will remain intact. This universal accessibility has contributed to the popularity of PDF as a preferred format for sharing and distributing documents across diverse platforms and systems.
PDF’s capability to encapsulate a complete document, including text, fonts, graphics, and formatting, makes it a reliable choice for various applications. Whether it’s sharing important reports, publishing e-books, distributing forms, or delivering professional presentations, PDF ensures consistent document rendering and reliable preservation of content across different environments.
What is PS File Format?
The PS (PostScript) file format is a page description language developed by Adobe Systems. It is commonly used for printing and is supported by a wide range of printers and imaging devices. PS files contain instructions that describe how elements such as text, images, and graphics should be rendered on a printed page.
PS files are created by applications that generate PostScript output, such as Adobe Illustrator, Adobe InDesign, or other graphics software. They are primarily used in professional printing workflows, where high-quality and consistent output is required.
The PS file format is based on a stack-based programming language, where commands and operands are placed on a stack and executed in a sequential manner. This allows for precise control over page layout, typography, color, and other printing parameters.
PS files are typically text-based and can be opened and edited with a text editor. They consist of a series of ASCII characters that represent the PostScript code. The code describes the arrangement and appearance of objects on a page, including text positioning, image placement, and graphical transformations.
While PS files are primarily used for printing, they can also be converted to other formats for digital distribution or further processing. For example, PS files can be converted to PDF (Portable Document Format) files, which are widely supported and can be easily viewed and printed on various devices.
