Transform PDF to GIF via Java
On Premise Java API to Render PDF to GIF without using any third party application
Converting PDF to GIF is a simple two-step process that can be accomplished with the help of Aspose.Total for Java. Aspose.Total for Java is a comprehensive suite of APIs that provide powerful document processing capabilities.
The first step in the conversion process is to render the PDF file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF processing API that enables developers to create, edit, convert, and manipulate PDF documents. It also provides features such as document splitting, merging, and extraction of text and images.
The second step is to convert the DOC file to GIF using Aspose.Words for Java. Aspose.Words for Java is a powerful document processing API that enables developers to create, edit, convert, and manipulate Word documents. It also provides features such as document splitting, merging, and extraction of text and images.
Once the PDF file has been rendered to DOC and then converted to GIF, the resulting GIF file can be used for various purposes such as creating presentations, web pages, and other documents. Aspose.Total for Java makes it easy to convert PDF to GIF with just two simple steps. It is a comprehensive suite of APIs that provide powerful document processing capabilities.
Java API to Convert PDF to GIF
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 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.GIF
outputDocument.save("output.gif", SaveFormat.GIF);
Open Password Protected PDF Document via Java
While converting PDF 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 PDF using the owner’s password.
Document document = new Document("input.pdf", "password");
// save PDF 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);
}
