Modern API

Aspose.Slides for C++ 24.4 delivers a modernized API that will see a gradual reduction in reliance on System::Drawing dependencies. This will ensure a more efficient development experience for C++ programmers. The following new classes and enums have been introduced in this version:

• IImage - A class representing the raster or vector image.
• ImageFormat - A class representing the file format of the image.
• Images - A static class containing methods to instantiate IImage.

Password Protected Macro Detection

With the latest version of the C++ presentation API, users can easily identify presentations with password-protected macros.

Zip64 Support

Seamlessly export your presentations to the Zip64 format for larger files and optimize your PowerPoint processing workflows on Windows-based systems. The following C++ code example highlights the usage of the newly added set_Zip64Mode() property that enables Zip64 export.

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"demo.pptx");
System::SharedPtr<PptxOptions> options = System::MakeObject<PptxOptions>();
options->set_Zip64Mode(Aspose::Slides::Export::Zip64Mode::Always);
pres->Save(u"demo-zip64.pptx", Aspose::Slides::Export::SaveFormat::Pptx, options);

Rasterize Text as Bitmap

Rasterizing presentation text as a bitmap and saving it to PDF documents has never been this easy. Version 24.4 of the PowerPoint API supports this functionality with the set_RasterizeUnsupportedFontStyles property so that you can export optimized PDF files. The following code snippet demonstrates the method usage:

System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>();
System::SharedPtr<PdfOptions> options = System::MakeObject<PdfOptions>();
options->set_RasterizeUnsupportedFontStyles(true);
pres->Save(u"pres.pdf", Aspose::Slides::Export::SaveFormat::Pdf, options);
