Public API Changes
Presentation Slide Show Setup Settings support
We implemented support for Presentation Slide Show Settings.
These are the relevant classes and methods:
- Presentation::get_SlideShowSettings() method - allows you to specify the slide show settings for a presentation.
- SlideShowSettings class - represents the slide show settings for the presentation. It provides these methods:
- BrowsedAtKiosk class - represents the Browsed at a kiosk (full screen) parameter.
- BrowsedByIndividual class - represents the Browsed by individual (window) parameter.
- PresentedBySpeaker class - represents the Presented by a speaker (full screen) parameter.
- SlidesRange class - represents the slides range.
This C++ code shows you how to set the Presented by a speaker parameter for a slide show:
auto pres = System::MakeObject<Presentation>();
pres->get_SlideShowSettings()->set_SlideShowType(System::MakeObject<PresentedBySpeaker>());
pres->Save(u"pres.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
Browsed by individual parameter:
auto pres = System::MakeObject<Presentation>();
auto browsedByIndividual = System::MakeObject<BrowsedByIndividual>();
browsedByIndividual->set_ShowScrollbar(true);
pres->get_SlideShowSettings()->set_SlideShowType(browsedByIndividual);
pres->Save(u"pres.pptx", Aspose::Slides::Export::SaveFormat::Pptx);
Effect::get_Sound() and Effect::set_Sound() methods have been added
Support for Embedded sound effect has been implemented through the Effect::get_Sound() and Effect::set_Sound() methods.
auto presentation = System::MakeObject<Presentation>(u"demo.pptx");
auto slide = presentation->get_Slides()->idx_get(0);
// Gets the effects sequence for the slide
auto effectsSequence = slide->get_Timeline()->get_MainSequence();
for (auto& effect : effectsSequence)
{
if (effect->get_Sound() == nullptr)
{
continue;
}
// Extracts the effect sound in byte array
auto audio = effect->get_Sound()->get_BinaryData();
}
