com.aspose.words.OfficeMathRenderer

public class OfficeMathRenderer
extends NodeRendererBase

Provides methods to render an individual OfficeMath to a raster or vector image or to a Graphics object.

Examples:

Shows how to measure and scale shapes.

 
 Document doc = new Document(getMyDir() + "Office math.docx");

 OfficeMath officeMath = (OfficeMath) doc.getChild(NodeType.OFFICE_MATH, 0, true);
 OfficeMathRenderer renderer = new OfficeMathRenderer(officeMath);

 Assert.assertEquals(122.0f, renderer.getOpaqueBoundsInPoints().getWidth(), 0.25f);
 Assert.assertEquals(14.2f, renderer.getOpaqueBoundsInPoints().getHeight(), 0.1f);
