Public API Changes

Exporting mathematical equations to MathML format

Methods IMathParagraph.WriteAsMathMl and IMathBlock.WriteAsMathMl have been added. You can use them to export a mathematical paragraph or block to MathML format. The presentation MathML markup is used.

using (Presentation pres = new Presentation())
{
	var autoShape = pres.Slides[0].Shapes.AddMathShape(0, 0, 500, 50);
	var mathParagraph = ((MathPortion)autoShape.TextFrame.Paragraphs[0].Portions[0]).MathParagraph;

	mathParagraph.Add(new MathematicalText("a").SetSuperscript("2").Join("+").Join(new MathematicalText("b").SetSuperscript("2")).Join("=").Join(new MathematicalText("c").SetSuperscript("2")));

	using (Stream stream = new FileStream("mathml.xml", FileMode.Create))
		mathParagraph.WriteAsMathMl(stream);
}

Contents of the resulting file:

<math display='block' xmlns="http://www.w3.org/1998/Math/MathML">
    <mrow>
        <msup>
            <mi>a</mi>
            <mn>2</mn>
        </msup>
        <mo>+</mo>
        <msup>
            <mi>b</mi>
            <mn>2</mn>
