Hi,

We have a problem with mathematical formulas using Aspose.words.jdk16 for java,(version 17.7) I am not able to print some mathematical formulas and getting error while generating pdf.

    Document doc = new Document();
	DocumentBuilder docBuilder = new DocumentBuilder(doc);
	String mathEquation1  = "<math xmlns='http://www.w3.org/1998/Math/MathML' display='block'>  
           <mfrac linethickness='3px'>    <mfrac bevelled='true'>      <mn>1</mn>      <mi>x</mi>    
           </mfrac>    <mrow>      <mi>y</mi>      <mo>&minus;</mo>      <mn>2</mn>    </mrow>  </mfrac></math>";
	String mathEquation2  = "<math xmlns='http://www.w3.org/1998/Math/MathML'>  <msup>    <mrow>      <mo>(</mo>        <mrow>          <mrow><mn>3</mn><mi>x</mi></mrow>          <mo>-</mo>          <mrow><mn>2</mn><mi>y</mi></mrow>        </mrow>      <mo>)</mo>    </mrow>    <mn>2</mn>  </msup></math>";
	String mathEquation3 = "<math xmlns='http://www.w3.org/1998/Math/MathML'> <mrow>   <msup>     <mfenced>       <mrow>         <mi>a</mi>         <mo>+</mo>         <mi>b</mi>       </mrow>     </mfenced>     <mn>2</mn>   </msup> </mrow> </math>";
	
	docBuilder.insertHtml(mathEquation1);
	docBuilder.insertHtml("<br>");
	docBuilder.insertHtml(mathEquation2);
	docBuilder.insertHtml("<br>");
	docBuilder.insertHtml(mathEquation3);
	doc.updateFields();
    doc.save("D:\\MathEquation.pdf");

I got the Aspose 17.7.1 hotfix for my issue. I have checked the aspose 17.7.1.
Aspose team has resolved the issue. But some minor issue I am facing again.Now Equations are coming, But they are not left aligned.They are coming in center aligned by default.

it should come left aligned by default.

@Prahalad

Thanks for your feedback. We are looking into the issue and will guide you accordingly.

@Prahalad,

Regarding alignment issue, please use the following code:

NodeCollection maths = doc.GetChildNodes(NodeType.OfficeMath, true);
foreach (OfficeMath math in maths)
{
    if ((math.ParentNode.NodeType != NodeType.OfficeMath))
    {
        math.DisplayType = OfficeMathDisplayType.Display;
        math.Justification = OfficeMathJustification.Left;
    }
}
