Examples
Shows how to measure and scale shapes.
Document doc = new Document(MyDir + "Office math.docx");
OfficeMath officeMath = (OfficeMath)doc.GetChild(NodeType.OfficeMath, 0, true);
OfficeMathRenderer renderer = new OfficeMathRenderer(officeMath);
// Verify the size of the image that the OfficeMath object will create when we render it.
Assert.AreEqual(122.0f, renderer.SizeInPoints.Width, 0.25f);
Assert.AreEqual(13.0f, renderer.SizeInPoints.Height, 0.15f);
Assert.AreEqual(122.0f, renderer.BoundsInPoints.Width, 0.25f);
Assert.AreEqual(13.0f, renderer.BoundsInPoints.Height, 0.15f);
// Shapes with transparent parts may contain different values in the "OpaqueBoundsInPoints" properties.
Assert.AreEqual(122.0f, renderer.OpaqueBoundsInPoints.Width, 0.25f);
Assert.AreEqual(14.2f, renderer.OpaqueBoundsInPoints.Height, 0.1f);
// Get the shape size in pixels, with linear scaling to a specific DPI.
Rectangle bounds = renderer.GetBoundsInPixels(1.0f, 96.0f);
Assert.AreEqual(163, bounds.Width);
Assert.AreEqual(18, bounds.Height);
// Get the shape size in pixels, but with a different DPI for the horizontal and vertical dimensions.
bounds = renderer.GetBoundsInPixels(1.0f, 96.0f, 150.0f);
Assert.AreEqual(163, bounds.Width);
Assert.AreEqual(27, bounds.Height);
// The opaque bounds may vary here also.
bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f);
Assert.AreEqual(163, bounds.Width);
Assert.AreEqual(19, bounds.Height);
bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f, 150.0f);
Assert.AreEqual(163, bounds.Width);
Assert.AreEqual(29, bounds.Height);
