Transform CGM to GIF via Java
On Premise Java API to Render CGM to GIF without using any third party application
Converting CGM to GIF is a simple process that can be done in two steps. The first step is to render the CGM file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF processing API that is part of the Aspose.Total for Java package. This API allows you to easily convert CGM files to DOC format.
The second step is to use Aspose.Words for Java to convert the DOC file to GIF. Aspose.Words for Java is a powerful document processing API that is also part of the Aspose.Total for Java package. This API allows you to easily convert DOC files to GIF format.
By using Aspose.PDF for Java and Aspose.Words for Java, you can easily convert CGM to GIF in just two steps. Aspose.Total for Java is a comprehensive package that includes both of these powerful APIs, making it easy to convert CGM to GIF quickly and efficiently.
Java API to Convert CGM 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 CGM file with an instance of Document class
Document document = new Document("template.cgm");
// save CGM 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 CGM Document via Java
While converting CGM 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 CGM using the owner’s password.
Document document = new Document("input.cgm", "password");
// save CGM 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);
}
