C++ API to Export CGM to GIF
Render CGM to GIF within C++ applications without requiring any third party application
Why to Convert CGM to GIF
The Graphics Interchange Format (GIF) is a bitmap image format that is widely used to display images on the web. It is a popular format for its ability to support animation, transparency, and interlacing. GIFs are also widely used for simple graphics and logos. On the other hand, Computer Graphics Metafile (CGM) is a vector graphics format used for storing and exchanging graphics data. It is mainly used in engineering and technical drawings.
Therefore, it is often necessary to convert CGM to GIF in order to make the graphics more accessible and compatible with other applications.
How Aspose.Total Helps for CGM to GIF Conversion
Aspose.Total for C++ is a suite of file format automation libraries that enables C++ developers to easily convert CGM to GIF in two simple steps. Firstly, you can use Aspose.PDF for C++ API to convert CGM file format to DOC. Secondly, by using advanced Word Document Processing API Aspose.Words for C++, you can export DOC to GIF.
Aspose.PDF for C++ is a powerful PDF manipulation API that enables developers to create, edit, convert, and print PDF documents from within their own applications. It supports a wide range of features such as text extraction, document conversion, document signing, and more.
Aspose.Words for C++ is a powerful Word document processing API that enables developers to create, edit, convert, and print Word documents from within their own applications. It supports a wide range of features such as document conversion, text extraction, document signing, and more.
Aspose.Total for C++ is a comprehensive suite of file format automation libraries that enables developers to easily convert CGM to GIF. It provides a simple and efficient way to convert CGM to GIF without any manual intervention.
C++ API to Render CGM to GIF
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 Gif
wordDoc->Save(u"output.Gif");
Change Password of CGM Document via C++
In the process of rendering CGM to GIF, 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 GIF File Editing via C++
You can also restrict GIF 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.Gif");
