Aspose::Words::Rendering::NodeRendererBase::get_BoundsInPoints method

NodeRendererBase::get_BoundsInPoints method

Gets the actual bounds of the shape in points.

System::Drawing::RectangleF Aspose::Words::Rendering::NodeRendererBase::get_BoundsInPoints() const

Remarks

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

Examples

Shows how to measure and scale shapes.

auto doc = MakeObject<Document>(MyDir + u"Office math.docx");

auto officeMath = System::ExplicitCast<OfficeMath>(doc->GetChild(NodeType::OfficeMath, 0, true));
auto renderer = MakeObject<OfficeMathRenderer>(officeMath);

// Verify the size of the image that the OfficeMath object will create when we render it.
ASSERT_NEAR(122, renderer->get_SizeInPoints().get_Width(), 0.25f);
ASSERT_NEAR(13.0f, renderer->get_SizeInPoints().get_Height(), 0.15f);

ASSERT_NEAR(122, renderer->get_BoundsInPoints().get_Width(), 0.25f);
ASSERT_NEAR(13.0f, renderer->get_BoundsInPoints().get_Height(), 0.15f);

// Shapes with transparent parts may contain different values in the "OpaqueBoundsInPoints" properties.
ASSERT_NEAR(122, renderer->get_OpaqueBoundsInPoints().get_Width(), 0.25f);
ASSERT_NEAR(14.2f, renderer->get_OpaqueBoundsInPoints().get_Height(), 0.1f);

// Get the shape size in pixels, with linear scaling to a specific DPI.
System::Drawing::Rectangle bounds = renderer->GetBoundsInPixels(1.0f, 96.0f);

ASSERT_EQ(163, bounds.get_Width());
ASSERT_EQ(18, bounds.get_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_EQ(163, bounds.get_Width());
ASSERT_EQ(27, bounds.get_Height());

// The opaque bounds may vary here also.
bounds = renderer->GetOpaqueBoundsInPixels(1.0f, 96.0f);

ASSERT_EQ(163, bounds.get_Width());
ASSERT_EQ(19, bounds.get_Height());

bounds = renderer->GetOpaqueBoundsInPixels(1.0f, 96.0f, 150.0f);

ASSERT_EQ(163, bounds.get_Width());
ASSERT_EQ(29, bounds.get_Height());
