Transform EPUB to GIF via Java

On Premise Java API to Render EPUB to GIF without using any third party application

Converting an EPUB file to GIF can be done in two simple steps using the powerful APIs from Aspose.Total for Java. Aspose.Total for Java is a comprehensive package of APIs that can be used to create, edit, and convert documents.

The first step is to render the EPUB file to DOC using Aspose.PDF for Java. This API is specifically designed to work with PDF documents and can be used to convert EPUB files to DOC. It is a powerful API that can be used to create, edit, and convert PDF documents.

The second step is to convert the DOC file to GIF using Aspose.Words for Java. This API is specifically designed to work with Word documents and can be used to convert DOC files to GIF. It is a powerful API that can be used to create, edit, and convert Word documents.

By using these two APIs from Aspose.Total for Java, you can easily convert an EPUB file to GIF. The process is simple and straightforward and can be done in just a few steps. With the help of these powerful APIs, you can quickly and easily convert EPUB files to GIF.

Java API to Convert EPUB to GIF

Open EPUB file using Document class
Convert EPUB to DOC by using save method
Load DOC file by using Document class of Aspose.Words
Save the document to GIF format using save method and set GIF as SaveFormat

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.GIF
outputDocument.save("output.gif", SaveFormat.GIF);   

Open Password Protected EPUB Document via Java

While converting EPUB to GIF, 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 GIF Document to a Database via Java

While saving your input document to GIF 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 GIF 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.GIF);
    // 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);
}
