C++ API to Export XPS to MHTML
Render XPS to MHTML within C++ applications without requiring any third party application
Why to Convert XPS to MHTML?
XPS (XML Paper Specification) is a document format developed by Microsoft that is used to store documents in a fixed layout. It is similar to PDF, but is not as widely used. MHTML (MIME HTML) is a web page archive format used to save web pages for offline viewing. It is a combination of HTML code and resources such as images, audio, and video. Converting XPS to MHTML allows users to view the documents offline, and also to share them with others.
How Aspose.Total Helps for XPS to MHTML Conversion?
Aspose.Total for C++ is a suite of file format automation libraries that enables C++ developers to easily convert XPS to MHTML in two simple steps. Firstly, the Aspose.PDF for C++ API can be used to convert XPS file format to DOC. Secondly, the advanced Word Document Processing API Aspose.Words for C++ can be used to export DOC to MHTML. This makes it easy for developers to quickly and easily convert XPS to MHTML without having to write complex code. Aspose.Total for C++ also provides a range of other features such as document manipulation, conversion, and rendering. It is a comprehensive suite of libraries that makes it easy for developers to work with a variety of file formats.
C++ API to Render XPS to MHTML
Get Started with C++ File Automation APIs
Install from command line as nuget install Aspose.Total.Cpp or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.Cpp.
Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .
// load XPS file with an instance of Document class reference
auto doc = MakeObject<Document>(u"sourceFile.xps");
// save XPS as a DOC
doc->Save(u"DocOutput.doc", SaveFormat::Doc);
// load DOC with an instance of Document
System::SharedPtr<Document> wordDoc = System::MakeObject<Document>(u"DocOutput.doc");
// save document as Mhtml
wordDoc->Save(u"output.Mhtml");
Change Password of XPS Document via C++
In the process of rendering XPS to MHTML, you can open a password protected XPS and also change its password. In order to change the password of a XPS file, you must know the owner password of that document. You can load password protected PDF document with Aspose.PDF for C++ by specifying its owner password and use ChangePasswords method to change the password.
// load an existing XPS Document
auto doc = MakeObject<Document>(L"input.xps", L"owner");
// change password of XPS Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Restrict MHTML File Editing via C++
You can also restrict MHTML file editing using using Aspose.Words for C++ API. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. API enables you to control the way you restrict the content using the ProtectionType enumeration parameter. The following code example demonstrates how to restrict editing in a document so only editing in form fields is possible.
// load Doc with an instance of Document
auto doc = System::MakeObject<Document>("input.doc");
// document protection only works when document protection is turned and only editing in form fields is allowed.
doc->Protect(ProtectionType::AllowOnlyFormFields, u"password");
// save the protected document.
doc->Save(u"Protected.Mhtml");
