{
  ISequence sequence = pres.Slides[0].Timeline.MainSequence;
  IAutoShape autoShape = (IAutoShape)pres.Slides[0].Shapes[0];
  
  foreach (IParagraph paragraph in autoShape.TextFrame.Paragraphs)
  {
    IEffect[] effects = sequence.GetEffectsByParagraph(paragraph);
	if (effects.Length > 0)
      Console.WriteLine("Paragraph \"" + paragraph.Text + "\" has " + effects[0].Type + " effect.");
  }
}

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

A new Conformance property has been added to PptxOptions class. It allows saving the presentation with Strict and Transitional Open XML Presentation conformance class.

PptxOptions.Conformance property is of type Conformance enumeration. This enum consists of three members:

• 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.

Conformance property has value “Ecma376_2006” by default.

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

using (Presentation presentation = new Presentation("Presentation.pptx"))
{
  PptxOptions opt = new PptxOptions() { Conformance = Conformance.Iso29500_2008_Strict };
  presentation.Save("PresOut.pptx", SaveFormat.Pptx, opt);
}
