Aspose::Words::Rendering::NodeRendererBase::get_OpaqueBoundsInPoints method

NodeRendererBase::get_OpaqueBoundsInPoints method

Gets the opaque bounds of the shape in points.

System::Drawing::RectangleF Aspose::Words::Rendering::NodeRendererBase::get_OpaqueBoundsInPoints()

Remarks

This property returns the opaque (i.e. transparent parts of the shape are ignored) bounding box of the shape. The bounds takes the shape rotation into account.

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());
