Aspose::Words::Rendering::OfficeMathRenderer::OfficeMathRenderer constructor

OfficeMathRenderer::OfficeMathRenderer constructor

Initializes a new instance of this class.

Aspose::Words::Rendering::OfficeMathRenderer::OfficeMathRenderer(const System::SharedPtr<Aspose::Words::Math::OfficeMath> &math)
ParameterTypeDescription
mathconst System::SharedPtr<Aspose::Words::Math::OfficeMath>&The OfficeMath object that you want to render.

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(119.0f, renderer->get_SizeInPoints().get_Width(), 0.2f);
ASSERT_NEAR(13.0f, renderer->get_SizeInPoints().get_Height(), 0.1f);

ASSERT_NEAR(119.0f, renderer->get_BoundsInPoints().get_Width(), 0.2f);
ASSERT_NEAR(13.0f, renderer->get_BoundsInPoints().get_Height(), 0.1f);

// Shapes with transparent parts may contain different values in the "OpaqueBoundsInPoints" properties.
ASSERT_NEAR(119.0f, renderer->get_OpaqueBoundsInPoints().get_Width(), 0.2f);
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(159, 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(159, bounds.get_Width());
ASSERT_EQ(28, bounds.get_Height());

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

ASSERT_EQ(159, bounds.get_Width());
ASSERT_EQ(18, bounds.get_Height());

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

ASSERT_EQ(159, bounds.get_Width());
