Public API Changes

GetEffectsByParagraph() method has been added to ISequence and Sequence classes

GetEffectsByParagraph() method has been added to ISequence and Sequence classes. It returns the array of effects for the specified text paragraph.

System::ArrayPtr<System::SharedPtr<IEffect>> GetEffectsByParagraph(System::SharedPtr<IParagraph> paragraph);

Usage example:

{
    System::SharedPtr<Presentation> pres = System::MakeObject<Presentation>(u"Presentation.pptx");
    System::Details::DisposeGuard<1> __dispose_guard_0({pres});
    try
    {
        System::SharedPtr<ISequence> sequence = pres->get_Slides()->idx_get(0)->get_Timeline()->get_MainSequence();
        System::SharedPtr<IAutoShape> autoShape = System::DynamicCast<Aspose::Slides::IAutoShape>(pres->get_Slides()->idx_get(0)->get_Shapes()->idx_get(0));

        auto paragraph_enumerator = autoShape->get_TextFrame()->get_Paragraphs()->GetEnumerator();
        while (paragraph_enumerator->MoveNext())
        {
            auto paragraph = paragraph_enumerator->get_Current();
            System::ArrayPtr<System::SharedPtr<IEffect>> effects = sequence->GetEffectsByParagraph(paragraph);
            if (effects->get_Length() > 0)
                System::Console::WriteLine(System::String(u"Paragraph \"") + paragraph->get_Text() + u"\" has " + System::ObjectExt::ToString(effects[0]->get_Type()) + u" effect.");
        }
    }
    catch(...)
    {
        __dispose_guard_0.SetCurrentException(std::current_exception());
    }
}

Saving presentation with Strict and Transitional conformance class option has been added

get_Conformance() and set_Conformance() methods have been added to Aspose::Slides::Export::PptxOptions class. The methods allows saving the presentation with Strict and Transitional Open XML Presentation conformance class.

Aspose::Slides::Export::Conformance get_Conformance();
void set_Conformance(Aspose::Slides::Export::Conformance value);

Aspose::Slides::Export::Conformance enum consists of three named constants:

Ecma376_2006 - Specifies that the document conforms to the ECMA376:2006.
Iso29500_2008_Transitional - Specifies that the document conforms to the ISO/IEC 29500:2008 Transitional conformance class.
Iso29500_2008_Strict - Specifies that the document conforms to the ISO/IEC 29500:2008 Strict conformance class.

The default value is Ecma376_2006.

For example, the following code allows saving the presentation in Strict format.

{
    System::SharedPtr<Presentation> presentation = System::MakeObject<Presentation>(u"Presentation.pptx");
    System::Details::DisposeGuard<1> __dispose_guard_0({presentation});
    try
    {
        System::SharedPtr<PptxOptions> opt = System::MakeObject<PptxOptions>();
        opt->set_Conformance(Aspose::Slides::Export::Conformance::Iso29500_2008_Strict);
        presentation->Save(u"PresOut.pptx", Aspose::Slides::Export::SaveFormat::Pptx, opt);
    }
    catch(...)
    {
        __dispose_guard_0.SetCurrentException(std::current_exception());
    }
}
