NodeRendererBaseGetBoundsInPixels Method (Single, Single)

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

Namespace:  Aspose.Words.Rendering
Assembly:  Aspose.Words (in Aspose.Words.dll) Version: 20.3
Syntax
public Rectangle GetBoundsInPixels(
	float scale,
	float dpi
)

Parameters

scale
Type: SystemSingle
The zoom factor (1.0 is 100%).
dpi
Type: SystemSingle
The resolution (horizontal and vertical) to convert from points to pixels (dots per inch).

Return Value

Type: Rectangle
The actual (as rendered on the page) bounding box of the shape in pixels.
Remarks

This method converts BoundsInPoints into rectangle in pixels.

Examples
Shows how to measure and scale shapes.
// Open a document that contains an OfficeMath object
Document doc = new Document(MyDir + "Office math.docx");

// Create a renderer for the OfficeMath object 
OfficeMath officeMath = (OfficeMath)doc.GetChild(NodeType.OfficeMath, 0, true);
OfficeMathRenderer renderer = new OfficeMathRenderer(officeMath);

// We can measure the size of the image that the OfficeMath object will create when we render it
Assert.AreEqual(117.0f, renderer.SizeInPoints.Width, 0.1f);
Assert.AreEqual(12.9f, renderer.SizeInPoints.Height, 0.1f);

Assert.AreEqual(117.0f, renderer.BoundsInPoints.Width, 0.1f);
Assert.AreEqual(12.9f, renderer.BoundsInPoints.Height, 0.1f);

// Shapes with transparent parts may return different values here
Assert.AreEqual(117.0f, renderer.OpaqueBoundsInPoints.Width, 0.1f);
Assert.AreEqual(14.7f, 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(156, 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(156, bounds.Width);
Assert.AreEqual(27, bounds.Height);

// The opaque bounds may vary here also
bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f);
Assert.AreEqual(156, bounds.Width);
Assert.AreEqual(20, bounds.Height);

bounds = renderer.GetOpaqueBoundsInPixels(1.0f, 96.0f, 150.0f);
Assert.AreEqual(156, bounds.Width);
Assert.AreEqual(31, bounds.Height);
