Preserve as normal text

By default, characters in equations in a Word document are in italics. However, you can also include normal text within an equation using LaTeX.

The following code example shows how to preserve text as normal text, without any default formatting, within an equation using LaTeX.

JAVA

//Creates a new Word document.

document.ensureMinimal();
//Appends a border box equation using LaTeX.
WMath math = document.getLastParagraph().appendMath("\\boxed{{x}^{2}+{y}^{2}={z}^{2}}");
//Applies math justification.
math.getMathParagraph().setJustification(MathJustification.Left);
//Saves the Word document.
document.save("Sample.docx", FormatType.Docx);
//Closes the document.
document.close();

Modify equation using LaTeX

You can modify the text of an equation by replacing the string value in the LaTeX API, which retrieves the LaTeX string representation of the professional equation in the Word document.

The following code snippet shows how to modify a LaTeX equation in a Word document.

JAVA

//Opens an existing Word document.
WordDocument document = new WordDocument("Template.docx", FormatType.Automatic);
//Adds one section and one paragraph to the document.
document.ensureMinimal();

//Accesses the first paragraph from the last section of the document.
WParagraph paragraph = (WParagraph)document.getLastSection().getBody().getChildEntities().get(0);
//Retrieves the first math equation in the paragraph, if it exists.
WMath math = (WMath) paragraph.getChildEntities().get(0);
if (math != null)
{
    //Gets the LaTeX representation of the math equation.
    String laTeX = math.getMathParagraph().getLaTeX();
    //Replaces occurrences of 'x' with 'k' in the LaTeX representation.
    math.getMathParagraph().setLaTeX(laTeX.replace("x", "k"));
}

//Saves the Word document.
document.save("Sample.docx", FormatType.Docx);
//Closes the document.
document.close();
