Render CGM to PPS within C++ Applications
Convert CGM to PPS within your C++ Applications without using Microsoft® PowerPoint
Why to Convert CGM to PPS?
CGM (Computer Graphics Metafile) is a vector graphics format used for storing and exchanging graphics data. It is widely used in engineering and technical applications. On the other hand, PPS (PowerPoint Show) is a presentation format used by Microsoft PowerPoint. It is used to store slides in a single file. Therefore, if you want to use the CGM data in a PowerPoint presentation, you need to convert it to PPS format.
How Aspose.Total Helps for CGM to PPS Conversion?
If you are a C++ developer looking to integrate CGM to PPS conversion feature inside your C++ applications, you can do it in two simple steps. You can export CGM to PPTX by using Aspose.PDF for C++ . Secondly, by using Aspose.Slides for C++ , you can convert PPTX to PPS. Both APIs come under Aspose.Total for C++ package.
Aspose.PDF for C++ is a powerful PDF manipulation API that enables you to create, read, edit, and convert PDF documents. It supports a wide range of features, including the ability to export CGM to PPTX. Aspose.Slides for C++ is a powerful presentation API that enables you to create, read, edit, and convert presentations. It supports a wide range of features, including the ability to convert PPTX to PPS.
Aspose.Total for C++ is a suite of APIs that includes Aspose.PDF for C++ and Aspose.Slides for C++. It enables you to create, read, edit, and convert documents and presentations. It also includes a wide range of features, including the ability to export CGM to PPTX and convert PPTX to PPS. With Aspose.Total for C++, you can easily integrate CGM to PPS conversion feature inside your C++ applications.
C++ API to Export CGM to PPS
- 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 PPS format using
Save
member function and set
Ppsas 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 Pps format
prs->Save(u"output.pps", Aspose::Slides::Export::SaveFormat::Pps);
Change Password of CGM Document via C++
In the process of rendering CGM to PPS, 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 PPS File via C++
After converting CGM to PPS, 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 PPS file
// instantiate a Presentation object that represents a PPS file
auto pres = System::MakeObject<Presentation>("output.pps");
// 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.pps", SaveFormat::Pps);
