Transform MHTML to PS via Java
On Premise Java API to Render MHTML to PS without using any third party application
You can convert MHTML to PS by using two simple steps. First you need to render MHTML file to DOC using Aspose.PDF for Java . After that, by using powerful Document Processing API Aspose.Words for Java , you can convert DOC to PS. Both APIs come under Aspose.Total for Java package.
Java API to Convert MHTML 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 MHTML file with an instance of Document class
Document document = new Document("template.mhtml");
// save MHTML 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 MHTML Document via Java
While converting MHTML 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 MHTML using the owner’s password.
Document document = new Document("input.mhtml", "password");
// save MHTML 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 MHTML File Format
MHTML, short for MIME HTML, is a web page archive format used to combine resources that are typically represented by external links (such as images, Flash animations, Java applets, and audio files) with HTML code into a single file. The resulting file can be saved and opened by web browsers.MHTML is supported by most major web browsers, including Microsoft Edge, Internet Explorer, Google Chrome, Mozilla Firefox, and Opera. Safari has limited support for MHTML. When a web page is saved as an MHTML file, the HTML code and the resources are typically encoded using the MIME type multipart/related. This type of encoding is necessary in order to maintain the correct sequence of the HTML code and the resources when they are combined into a single file. The MHTML format is often used for archiving web pages or for distributing web pages that need to be viewed offline.

A PostScript file is a text file that contains a description of a page or document to be printed. It is typically created by a word processor or other application, and then saved in the PS format. The file can be printed by any printer that supports the PostScript language.PS files are usually stored in one of two ways: as a single page, or as a multi-page document. Single page PS files are typically used for printing a single page, such as a letter or an invoice. Multi-page PS files are used for printing documents that span multiple pages, such as a book or a report. When a PS file is printed, the printer reads the file and interprets the instructions contained within it. The printer then produces a printed version of the document.PS files are typically much larger than other types of files, such as PDFs. This is because they contain a lot of detailed information about the document to be printed. For this reason, it is important to make sure that your printer has enough memory to store the entire PS file.PS files can be opened and edited with a text editor, such as Microsoft Word or Adobe Acrobat. However, it is important to be careful when editing a PS file, as even a small change can result in the file being unreadable by the printer. If you need to make changes to a PS file, it is best to save a copy of the file first, so that you can revert back to the original if necessary.
