Convert PDF to Microsoft PowerPoint

Aspose.PDF for C++ lets you track the progress of PDF to PPTX conversion.

During PDF to PPTX conversion, the text is rendered as Text where you can select/update it. Please note that in order to convert PDF files to PPTX format, Aspose.PDF provides a class named PptxSaveOptions. An object of the PptxSaveOptions class is passed as a second argument to the Document.Save(..) method method. The following code snippet shows the process for converting PDF files into PPTX format.

Simple conversion PDF to PPTX with Aspose.PDF for C++

In order to convert PDF to PPTX, Aspose.PDF for C++ advice to use the following code steps.

  1. Create an instance of Document class
  2. Create an instance of PptxSaveOptions class
  3. Use the Save method of the Document object to save the PDF as PPTX
void ConvertPDFtoPPTX()
{
    std::clog << __func__ << ": Start" << std::endl;
    // String for path name
    String _dataDir("C:\\Samples\\Conversion\\");

    // String for file name
    String infilename("JSON Fundamenals.pdf");
    String outfilename("JSON Fundamenals.pptx");

    // Open document
    auto document = MakeObject<Document>(_dataDir + infilename);

    // Save the output in PPTX format
    document->Save(_dataDir + outfilename, SaveFormat::Pptx);
    std::clog << __func__ << ": Finish" << std::endl;
}

Convert PDF to PPTX with Slides as Images

In case if you need to convert a searchable PDF to PPTX as images instead of selectable text, Aspose.PDF provides such a feature via Aspose.Pdf.PptxSaveOptions class. To achieve this, set property SlidesAsImages of PptxSaveOptios class to ‘true’ as shown in the following code sample.

void ConvertPDFtoPPTX_SlidesAsImages()
{
    std::clog << __func__ << ": Start" << std::endl;
    // String for path name
    String _dataDir("C:\\Samples\\Conversion\\");

    // String for file name
    String infilename("JSON Fundamenals.pdf");
    String outfilename("JSON Fundamenals.pptx");

    // Open document
    auto document = MakeObject<Document>(_dataDir + infilename);

    auto pptxOptions = MakeObject<PptxSaveOptions>();
    pptxOptions->set_SlidesAsImages(true);

    // Save the output in PPTX format
    document->Save(_dataDir + outfilename, pptxOptions);
    std::clog << __func__ << ": Finish" << std::endl;
}

Progress Detail of PPTX Conversion

Aspose.PDF for C++ lets you track the progress of PDF to PPTX conversion. The Aspose.Pdf.PptxSaveOptions class provides CustomProgressHandler property that can be specified to a custom method for tracking the progress of conversion as shown in the following code sample.

void ConvertPDFtoPPTX_ProgressDetailConversion()
{
    std::clog << __func__ << ": Start" << std::endl;
    // String for path name
    String _dataDir("C:\\Samples\\Conversion\\");

    // String for file name
    String infilename("JSON Fundamenals.pdf");
    String outfilename("JSON Fundamenals.pptx");

    // Open document
    auto document = MakeObject<Document>(_dataDir + infilename);

    auto pptxOptions = MakeObject<PptxSaveOptions>();
    //pptxOptions->set_SlidesAsImages(true);
    //Specify Custom Progress Handler
    pptxOptions->set_CustomProgressHandler(ShowProgressOnConsole);

    // Save the output in PPTX format
    document->Save(_dataDir + outfilename, pptxOptions);
    std::clog << __func__ << ": Finish" << std::endl;
}

Following is the custom method for displaying progress conversion.

void ShowProgressOnConsole(SharedPtr<UnifiedSaveOptions::ProgressEventHandlerInfo> eventInfo)
{
    switch (eventInfo->EventType)
    {
    case ProgressEventType::TotalProgress:
    std::clog << DateTime::get_Now().get_TimeOfDay() << " - Conversion progress : " << eventInfo->Value << std::endl;
    break;
    case ProgressEventType::ResultPageCreated:
    std::clog << DateTime::get_Now().get_TimeOfDay() << " - Result page's " << eventInfo->Value << " of " << eventInfo->MaxValue << " layout created." << std::endl;
    break;
    case ProgressEventType::ResultPageSaved:
    std::clog << DateTime::get_Now().get_TimeOfDay() << " - Result page's " << eventInfo->Value << " of " << eventInfo->MaxValue << " exported." << std::endl;
    break;
    case ProgressEventType::SourcePageAnalysed:
    std::clog << DateTime::get_Now().get_TimeOfDay() << " - Source page " << eventInfo->Value << " of " << eventInfo->MaxValue << " analyzed." << std::endl;
    break;
    default:
    break;
    }
}
