Work with mathematical equations
Overview
Build equations from mathematical elements such as fractions, radicals and subscripts. Read and edit the equation model in a presentation, or export it to LaTeX or MathML for another workflow. Equations can remain editable mathematical content instead of pictures.
Usage example
This C# example creates the editable equation x²/y as a superscript inside a stacked fraction. It saves math-equations.pptx and a PNG preview. The rendering host needs a suitable math font, such as Cambria Math.

using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.MathText;
using var presentation = new Presentation();
var shape = presentation.Slides[0].Shapes.AddMathShape(40, 40, 500, 120);
var mathParagraph = ((MathPortion)shape.TextFrame.Paragraphs[0].Portions[0]).MathParagraph;
var numerator = new MathematicalText("x").SetSuperscript("2");
var fraction = numerator.Divide(new MathematicalText("y"), MathFractionTypes.Bar);
mathParagraph.Add(new MathBlock(fraction));
presentation.Save("math-equations.pptx", SaveFormat.Pptx);
using var image = presentation.Slides[0].GetImage(1f, 1f);
image.Save("math-equations.png", Aspose.Slides.ImageFormat.Png);
FAQ
Can I create an equation by importing a LaTeX string?
The conversion here is export to LaTeX or MathML. Build the equation through the mathematical elements when creating it in the presentation.
Are equations stored as editable math objects or images?
The example stores an editable equation model in the PPTX, rather than replacing it with a picture. An image export is only a rendered view of that model.
How can I export an equation to MathML?
Export the mathematical paragraph through its MathML writer into a stream. Use the equation guide for the complete export workflow.
