C++ API to Export CGM to OTT
Render CGM to OTT within C++ applications without requiring any third party application
Why to Convert CGM to OTT
The CGM (Computer Graphics Metafile) file format is a vector graphics format used for storing and exchanging graphics data. It is widely used in the engineering and technical drawing fields. However, the OTT (OpenType Font) file format is a font format used for storing and exchanging font data. It is widely used in the publishing and printing fields. Therefore, it is necessary to convert CGM to OTT in order to make the graphics data available for publishing and printing.
How Aspose.Total Helps for CGM to OTT Conversion
Aspose.Total for C++ is a suite of file format automation libraries that allows C++ developers to easily convert CGM to OTT in two simple steps. Firstly, you can use Aspose.PDF for C++ API to convert CGM file format to DOC. This API provides a comprehensive set of features for creating, editing, and manipulating PDF documents. Secondly, by using the advanced Word Document Processing API Aspose.Words for C++, you can export DOC to OTT. This API provides a comprehensive set of features for creating, editing, and manipulating Word documents.

C++ API to Render CGM to OTT
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 CGM file with an instance of Document class reference
auto doc = MakeObject<Document>(u"sourceFile.cgm");
// save CGM 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 Ott
wordDoc->Save(u"output.Ott");
Change Password of CGM Document via C++
In the process of rendering CGM to OTT, you can open a password protected CGM and also change its password. In order to change the password of a CGM 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 CGM Document
auto doc = MakeObject<Document>(L"input.cgm", L"owner");
// change password of CGM Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Restrict OTT File Editing via C++
You can also restrict OTT 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.Ott");
