## GetSizeInPixels(*float, float*) {#getsizeinpixels}

Calculates the size of the shape in pixels for a specified zoom factor and resolution.

```csharp
public Size GetSizeInPixels(float scale, float dpi)
```

| Parameter | Type | Description |
| --- | --- | --- |
| scale | Single | The zoom factor (1.0 is 100%). |
| dpi | Single | The resolution (horizontal and vertical) to convert from points to pixels (dots per inch). |

### Return Value

The size of the shape in pixels.

## Remarks

This method converts [`SizeInPoints`](../sizeinpoints/) into size in pixels and it is useful when you want to create a bitmap for rendering the shape neatly onto the bitmap.

## Examples

Shows how to measure and scale shapes.

```csharp
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);
