Public API Changes

Another option has been added for setting external workbook path

The SetExternalWorkbook(System::String workbookPath, bool updateChartData) method has been added to the ChartData and IChartData classes.

The updateChartData parameter defines whether an excel workbook will be loaded or not. If the value is false only the workbook path will be updated. Chart data won’t be loaded and updated from the target workbook. This is useful when the target workbook doesn’t yet exist or is not available. If the value is true chart data will be updated from the target workbook as the SetExternalWorkbook(System::String) method does.

{
    auto pres = System::MakeObject<Presentation>();
    auto chart = pres->get_Slides()->idx_get(0)->get_Shapes()->AddChart(Aspose::Slides::Charts::ChartType::Pie, 50.0f, 50.0f, 400.0f, 600.0f, true);
    auto chartData = chart->get_ChartData();
    (System::DynamicCast_noexcept<Aspose::Slides::Charts::ChartData>(chartData))->SetExternalWorkbook(u"http://path/doesnt/exists", false);
}

New AddEffect() method has been added to the Sequence and ISequence classes

The AddEffect(System::SharedPtr, EffectType, EffectSubtype, EffectTriggerType) method has been added to the Sequence and ISequence classes.

It allows to add a new animation effect for a single paragraph.

{
    auto presentation = System::MakeObject&lt;Presentation&gt;(path + u"input.pptx");
    // select paragraph to add effect
    auto autoShape = System::DynamicCast&lt;Aspose::Slides::IAutoShape&gt;(presentation->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0));
    auto paragraph = autoShape->get_TextFrame()->get_Paragraphs()->idx_get(0);
    // add Fly animation effect to selected paragraph
    auto effect = presentation->get_Slides()->idx_get(0)->get_Timeline()->get_MainSequence()->AddEffect(
         paragraph, 
         Aspose::Slides::Animation::EffectType::Fly, 
         Aspose::Slides::Animation::EffectSubtype::Left, 
         Aspose::Slides::Animation::EffectTriggerType::OnClick);
