Public API Changes

Exporting mathematical equations to MathML format

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

Presentation pres = new Presentation();
try {
    IAutoShape autoShape = pres.getSlides().get_Item(0).getShapes().addMathShape(0, 0, 500, 50);
    IMathParagraph mathParagraph = ((MathPortion)autoShape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0)).getMathParagraph();

    mathParagraph.add(new MathematicalText("a").setSuperscript("2").join("+").join(new MathematicalText("b").setSuperscript("2")).join("=").join(new MathematicalText("c").setSuperscript("2")));

    FileOutputStream stream = null;
    try {
        stream = new FileOutputStream("mathml.xml");
        mathParagraph.writeAsMathMl(stream);
    } finally {
        if (stream != null) stream.close();
    }
} finally {
    if (pres != null) pres.dispose();
}

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>
        </msup>
        <mo>=</mo>
        <msup>
            <mi>c</mi>
            <mn>2</mn>
        </msup>
    </mrow>
</math>

New method iteratorJava() has been added to MathBlock and MathParagraph

A new iteratorJava() method has been added to MathBlock and MathParagraph classes.

This method allows to get an iterator that is fully complied with the Java Iterator logic.
