A Modernized API

Aspose.Slides for C++ 24.4 introduces an updated API aimed at reducing dependencies on System::Drawing gradually. Designed to streamline the development experience for C++ developers, this upgrade includes the following new additions:

• IImage: A class that represents raster or vector images.
• ImageFormat: A class that defines the file format of an image.
• Images: A static class with methods for creating instances of IImage.

Detecting Password Protected Macros

In the most recent update of the C++ presentation API, users can easily detect presentations containing password-protected macros on Linux machines.

Export Presentations in ZIP64 Format

Effortlessly save presentations as ZIP64 files and better manage larger presentations within your PowerPoint manipulation apps on Linux. This C++ sample code showcases the usage of the new set_Zip64Mode() property added in this release for 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);

Text to Bitmap Rasterization

Version 24.4 of the C++ API allows the rasterization of bold text as a bitmap and exporting it to PDF documents with the set_RasterizeUnsupportedFontStyles property. 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);
