Render PS to PPT within C++ Applications
Convert PS to PPT within your C++ Applications without using Microsoft® PowerPoint
Why to Convert
Are you a C++ developer looking to add a feature to your applications that allows for the conversion of PostScript (PS) files to Microsoft PowerPoint (PPT) files? If so, you are in luck. With the help of Aspose.Total for C++, you can easily and quickly integrate this feature into your C++ applications.
How Aspose.Total Helps for PS to PPT Conversion
Aspose.Total for C++ is a comprehensive suite of APIs that provides developers with the tools they need to create, manipulate, and convert a variety of file formats. In particular, it includes two APIs that are specifically designed to help with the conversion of PS to PPT files: Aspose.PDF for C++ and Aspose.Slides for C++.
The first step in the conversion process is to export the PS file to a PPTX file. This can be done using Aspose.PDF for C++. This API allows developers to easily convert PS files to a variety of other formats, including PPTX.
Once the PS file has been exported to a PPTX file, the second step is to convert the PPTX file to a PPT file. This can be done using Aspose.Slides for C++. This API provides developers with the ability to convert PPTX files to a variety of other formats, including PPT.
By using both Aspose.PDF for C++ and Aspose.Slides for C++, developers can easily and quickly integrate the feature of PS to PPT conversion into their C++ applications. Both of these APIs are included in the Aspose.Total for C++ package, making it easy for developers to access the tools they need.
C++ API to Export PS to PPT
- Open PS file using Document class reference
- Convert PS to PPTX by using Save method function
- Load PPTX document by using Presentation class reference
- Save the document to PPT format using
Save
member function and set
Pptas 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 PS file with an instance of Document class
auto doc = MakeObject<Document>(u"template.ps");
// save PS 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 Ppt format
prs->Save(u"output.ppt", Aspose::Slides::Export::SaveFormat::Ppt);
Change Password of PS Document via C++
In the process of rendering PS to PPT, you can open a password protected PS and also change its password. In order to change the password of a PS 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 PS Document
auto doc = MakeObject<Document>(L"input.ps", L"owner");
// change password of PS Document
doc->ChangePasswords(L"owner", L"newuser", L"newuser");
// save the document
doc->Save(L"output.Doc");
Add Images From Web in PPT File via C++
After converting PS to PPT, 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 PPT file
// instantiate a Presentation object that represents a PPT file
auto pres = System::MakeObject<Presentation>("output.ppt");
// 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.ppt", SaveFormat::Ppt);
