Transform CGM to MHTML via Java
On Premise Java API to Render CGM to MHTML without using any third party application
Converting CGM to MHTML 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 CGM file to DOC using Aspose.PDF for Java. Aspose.PDF for Java is a powerful PDF manipulation API that enables developers to create, edit, and convert PDF documents. It also provides the ability to render CGM files to DOC.
Once the CGM file has been rendered to DOC, the second step is to convert the DOC to MHTML using Aspose.Words for Java. Aspose.Words for Java is a powerful document processing API that enables developers to create, edit, and convert documents. It provides the ability to convert DOC files to MHTML.
By using Aspose.Total for Java, developers can easily convert CGM to MHTML in just two simple steps. Aspose.PDF for Java is used to render the CGM file to DOC, and Aspose.Words for Java is used to convert the DOC to MHTML. This makes it easy to convert CGM to MHTML without any hassle.
Java API to Convert CGM to MHTML
Conversion Requirements
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 .
| Document document = new Document("template.cgm"); | |
| document.save("DocOutput.doc", SaveFormat.DOC); | |
| Document outputDocument = new com.aspose.words.Document("DocOutput.doc"); | |
| outputDocument.save("output.mhtml", SaveFormat.MHTML); |
Open Password Protected CGM Document via Java
While converting CGM to MHTML, 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"); | |
| document.save("Output.doc", SaveFormat.DOC); |
Save MHTML Document to a Database via Java
While saving your input document to MHTML 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 MHTML 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.DOCM); | |
| // 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); | |
| } |
