Render PDF to SWF within C++ Applications
Convert PDF to SWF within your C++ Applications without using Microsoft® PowerPoint
If you are a C++ developer looking to add the ability to convert PDF files to SWF inside your C++ applications, you can do it in two simple steps. The first step is to use Aspose.PDF for C++ to export the PDF to PPTX. This API is part of the Aspose.Total for C++ package. The second step is to use Aspose.Slides for C++ to convert the PPTX to SWF.
Aspose.PDF for C++ is a powerful PDF manipulation API that allows developers to create, read, edit, convert, and print PDF documents from within their C++ applications. It supports a wide range of features such as document manipulation, text extraction, image extraction, and more. It also supports a wide range of file formats such as PDF, XPS, HTML, and more.
Aspose.Slides for C++ is a powerful presentation manipulation API that allows developers to create, read, edit, and convert presentations from within their C++ applications. It supports a wide range of features such as document manipulation, text extraction, image extraction, and more. It also supports a wide range of file formats such as PPTX, PPT, ODP, and more.
By using Aspose.PDF for C++ and Aspose.Slides for C++, you can easily add the ability to convert PDF to SWF inside your C++ applications. Both APIs are part of the Aspose.Total for C++ package, which provides a comprehensive set of APIs for developers to work with a wide range of file formats.
C++ API to Export PDF to SWF
- Open PDF file using Document class reference
- Convert PDF to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to SWF format using
Save
member function and set
Swfas SaveFormat
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
auto doc = MakeObject<Document>(u"template.pdf");
// save PDF as PPTX format
doc->Save(u"PptxOutput.pptx", SaveFormat::Pptx);
// instantiate a Presentation object that represents a PPTX file
SharedPtr<Presentation> prs = MakeObject<Presentation>(u"PptxOutput.pptx");
// save the presentation as Swf format
prs->Save(u"output.swf", Aspose::Slides::Export::SaveFormat::Swf);
Change Password of PDF Document via C++
In the process of rendering PDF to SWF, 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");
Add Images From Web in SWF File via C++
After converting PDF to SWF, you can also add images from web to your output document. Aspose.Slides for C++ supports operations with images in these popular formats: JPEG, PNG, BMP, GIF, and others. You can add one or several images on your computer onto a slide in a presentation. This sample code in C++ shows you how to add an image to a SWF file
// instantiate a Presentation object that represents a SWF file
auto pres = System::MakeObject<Presentation>("output.swf");
// get slide
auto slide = pres->get_Slides()->idx_get(0);
// initialize Web Client
auto webClient = System::MakeObject<WebClient>();
// get image data
auto imageData = webClient->DownloadData(System::MakeObject<Uri>(u"[REPLACE WITH URL]"));
// add image
auto image = pres->get_Images()->AddImage(imageData);
// add picture frame
slide->get_Shapes()->AddPictureFrame(ShapeType::Rectangle, 10.0f, 10.0f, 100.0f, 100.0f, image);
// save updated file
pres->Save(u"updated.swf", SaveFormat::Swf);
