C++ API to Export PDF to GIF
Render PDF to GIF within C++ applications without requiring any third party application
Why to Convert PDF to GIF
The Portable Document Format (PDF) is a widely used file format for documents. It is a popular choice for businesses and individuals alike due to its ability to preserve the original formatting of a document, regardless of the device or platform it is viewed on. However, PDFs are not always the best choice for sharing documents, as they can be difficult to view on certain devices. This is where converting PDFs to GIFs can be beneficial. GIFs are a popular image format that can be easily shared and viewed on any device.
How Aspose.Total Helps for PDF to GIF Conversion
Aspose.Total for C++ is a comprehensive file format automation library that allows C++ developers to easily convert PDFs to GIFs in two simple steps. Firstly, developers can use the Aspose.PDF for C++ API to convert PDF file formats to DOC. This API provides a wide range of features, such as the ability to extract text, images, and other content from PDFs. Secondly, developers can use the advanced Word Document Processing API, Aspose.Words for C++, to export DOC to GIF. This API provides a range of features, such as the ability to create, edit, and convert Word documents. With Aspose.Total for C++, developers can quickly and easily convert PDFs to GIFs with minimal effort.
C++ API to Render PDF 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 PDF file with an instance of Document class reference
auto doc = MakeObject<Document>(u"sourceFile.pdf");
// save PDF 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 PDF Document via C++
In the process of rendering PDF to GIF, you can open a password protected PDF and also change its password. In order to change the password of a PDF 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 PDF Document
auto doc = MakeObject<Document>(L"input.pdf", L"owner");
// change password of PDF 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");
