Aspose.Slides for C++ 23.12 empowers Windows developers to create, edit, convert, and manage presentations with unparalleled efficiency by delivering key enhancements for a seamless development experience.

Key Highlights

• Improved Image Handling: You can easily reduce the presentation size by deleting cropped areas of pictures using the newly added IPictureFillFormat::DeletePictureCroppedAreas method on Windows.
• Handout Export Layout: With Aspose.Slides for C++ 23.12, developers can export presentations with diverse handout layouts, replicating the functionality of “Print as Handouts” in PowerPoint.
• Enhanced Ink Object Control: The new InkOptions class introduced in this release provides better control over the appearance of Ink objects in exported documents.
• Optimized PDF Conversion: Using the latest release of the C++ presentation manipulation API, developers can achieve exceptional image quality when converting presentations to PDF format, resulting in professional-looking deliverables.
• Bug Fixes and Improvements: Users can benefit from numerous bug fixes addressing loading issues and ensuring reliable presentation processing.

Other Updates

• We have resolved loading errors encountered with various PPT, PPTX, and PPTM files.
• The get_NotesCommentsLayouting() method is deprecated, replaced by the set_SlidesLayoutOptions() method in version 23.12 of the C++ API for better control over layout options.

Render Presentations in Handout Format on Windows

This C++ example code highlights the rendering of a PowerPoint presentation in the form of the handout layout using Aspose.Slides for C++ 23.12:

auto pres = System::MakeObject<Presentation>(u"pres.pptx");

auto handoutLayoutingOptions = System::MakeObject<HandoutLayoutingOptions>();
handoutLayoutingOptions->set_Handout(HandoutType::Handouts4Horizontal);
handoutLayoutingOptions->set_PrintSlideNumbers(false);

auto options = System::MakeObject<RenderingOptions>();
options->set_SlidesLayoutOptions(handoutLayoutingOptions);

System::Drawing::Size size(1920, 1080);
pres->get_Slide(0)->GetThumbnail(options, size)->Save(u"pres-handout.png");

Introducing the InkOptions Class

We have introduced the InkOptions class which allows managing the Ink objects within the exported documents. This class includes get_HideInk() and set_HideInk() methods that can be used to show or hide the Ink elements in the exported files. The following code snippet demonstrates the usage of the set_HideInk() method:

auto pres = System::MakeObject<Presentation>(u"pres.pptx");

auto options = System::MakeObject<PdfOptions>();
options->get_InkOptions()->set_HideInk(true);

pres->Save(u"output.pptx", SaveFormat::Pdf, options);

Removed Cropped Areas of The Picture

You can easily remove the cropped areas from a picture using the IPictureFillFormat::DeletePictureCroppedAreas() method on Windows. Please check the following example code to learn more:

auto presentation = System::MakeObject<Presentation>(u"demo.pptx");
auto slide = presentation->get_Slide(0);

// Gets the PictureFrame
auto picFrame = System::AsCast<IPictureFrame>(slide->get_Shape(0));

// Deletes cropped areas of the PictureFrame image
auto croppedImage = picFrame->get_PictureFormat()->DeletePictureCroppedAreas();
