Transform EPUB to PS via Java
On Premise Java API to Render EPUB to PS without using any third party application
Converting an EPUB file to a PS file can be done in two easy steps. The first step is to render the EPUB file to a DOC file using the powerful Aspose.PDF for Java API. This API is part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for document processing. Once the EPUB file has been rendered to a DOC file, the second step is to use the Aspose.Words for Java API to convert the DOC file to a PS file. This API is also part of the Aspose.Total for Java package and provides a powerful set of features for document processing.
The Aspose.PDF for Java API provides a wide range of features for rendering EPUB files to DOC files. It supports a variety of formats, including EPUB, PDF, HTML, XPS, and more. It also provides a range of features for manipulating the content of the EPUB file, such as adding text, images, and tables.
The Aspose.Words for Java API provides a comprehensive set of features for converting DOC files to PS files. It supports a variety of formats, including DOC, DOCX, RTF, HTML, and more. It also provides a range of features for manipulating the content of the DOC file, such as adding text, images, and tables.
By using the Aspose.PDF for Java and Aspose.Words for Java APIs, you can easily convert an EPUB file to a PS file in two simple steps. Both APIs are part of the Aspose.Total for Java package, which provides a comprehensive set of APIs for document processing.
Java API to Convert EPUB to PS
Get Started with Java File Manipulation APIs
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 EPUB file with an instance of Document class
Document document = new Document("template.epub");
// save EPUB 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 EPUB Document via Java
While converting EPUB 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 EPUB using the owner’s password.
Document document = new Document("input.epub", "password");
// save EPUB as a DOC
document.save("DocOutput.doc", SaveFormat.DOC);
Save PS Document to a Database 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 EPUB File Format?
An EPUB file, also known as an Open eBook File, is a standardized format developed by the International Digital Publishing Forum (IDPF). It is based on XML (eXtensible Markup Language) and XHTML (eXtensible Hypertext Markup Language). EPUB files are designed for reading digital books and publications on various electronic devices such as e-readers, tablets, and smartphones.
EPUB files consist of three main components. The first component is the spine, which contains the main text of the book and defines the order in which the pages should be read. It provides the structural framework for the content.
The second component is the manifest, which serves as a catalog of all the files that make up the EPUB book. This includes the spine, cover image, table of contents, and any additional content. The manifest ensures that all the necessary files are properly linked and organized within the EPUB package.
The third component is the container, which stores the EPUB files in a compressed format. The container helps reduce file size and enables efficient distribution and storage of EPUB books.
EPUB files can be created using various software programs such as Adobe InDesign, Sigil, and Calibre. These tools provide authors and publishers with the ability to create, edit, and format EPUB books according to the specifications set by the IDPF. With EPUB being an open and widely adopted standard, readers can enjoy a seamless reading experience across different devices and platforms.
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.
