SizeInPoints

NodeRendererBase.SizeInPoints property

Gets the actual size of the shape in points.

public SizeF SizeInPoints { get; }

Remarks

This property returns the size of the actual (as rendered on the page) bounding box of the shape. The size takes into account shape rotation (if any).

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.That(renderer.SizeInPoints.Width, Is.EqualTo(122.0f).Within(0.25f));
Assert.That(renderer.SizeInPoints.Height, Is.EqualTo(13.0f).Within(0.15f));

Assert.That(renderer.BoundsInPoints.Width, Is.EqualTo(122.0f).Within(0.25f));
Assert.That(renderer.BoundsInPoints.Height, Is.EqualTo(13.0f).Within(0.15f));

// Shapes with transparent parts may contain different values in the "OpaqueBoundsInPoints" properties.
Assert.That(renderer.OpaqueBoundsInPoints.Width, Is.EqualTo(119.5f).Within(0.25f));
Assert.That(renderer.OpaqueBoundsInPoints.Height, Is.EqualTo(14.2f).Within(0.1f));

// Get the shape size in pixels, with linear scaling to a specific DPI.
Rectangle bounds = renderer.GetBoundsInPixels(1.0f, 96.0f);
string dpi96 = "DPI 96";
Assert.That(bounds.Width, Is.EqualTo(163), dpi96);
Assert.That(bounds.Height, Is.EqualTo(18), dpi96);

// 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);
string dpi96150 = "DPI 96 150";
Assert.That(bounds.Width, Is.EqualTo(163), dpi96150);
Assert.That(bounds.Height, Is.EqualTo(27), dpi96150);

// The opaque bounds may vary here also.
bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f);
string dpi96Opaque = "DPI 96 Opaque";
Assert.That(bounds.Width, Is.EqualTo(160), dpi96Opaque);
Assert.That(bounds.Height, Is.EqualTo(19), dpi96Opaque);

bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f, 150.0f);
string dpi96150Opaque = "DPI 96 150 Opaque";
Assert.That(bounds.Width, Is.EqualTo(160), dpi96150Opaque);
Assert.That(bounds.Height, Is.EqualTo(29), dpi96150Opaque);
