Render CGM to SWF within C++ Applications
Convert CGM to SWF within your C++ Applications without using Microsoft® PowerPoint
Why to Convert CGM to SWF?
CGM (Computer Graphics Metafile) is a vector graphics format used for storing and exchanging graphics data. It is widely used in engineering and technical drawings. SWF (Small Web Format) is a vector file format used for multimedia, vector graphics and ActionScript. It is widely used for creating interactive animations and games for webpages. Converting CGM to SWF can help you to create interactive animations and games for webpages.

Aspose.Slides for C++ is a powerful presentation manipulation API that enables you to create, read, edit, and convert presentations. It also allows you to convert PPTX to SWF. Aspose.Total for C++ is a suite of APIs that provides a comprehensive set of features for manipulating PDF, Word, Excel, PowerPoint, and other file formats. It includes Aspose.PDF for C++ and Aspose.Slides for C++.
By using Aspose.Total for C++, you can easily add CGM to SWF conversion feature inside your C++ applications. It is a cost-effective solution that helps you to save time and effort. It also provides a wide range of features and options that can help you to create interactive animations and games for webpages.
C++ API to Export CGM to SWF
- Open CGM file using Document class reference
- Convert CGM 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 CGM file with an instance of Document class
auto doc = MakeObject<Document>(u"template.cgm");
// save CGM 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 CGM Document via C++
In the process of rendering CGM to SWF, 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");
Add Images From Web in SWF File via C++
After converting CGM 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);
