## OfficeMathRenderer class


Provides methods to render an individual [OfficeMath](../../aspose.words.math/officemath/) to a raster or vector image or to a Graphics object. To learn more, visit the [Working with OfficeMath](https://docs.aspose.com/words/cpp/working-with-officemath/) documentation article.

## Examples



Shows how to measure and scale shapes. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>(System::String(get_MyDir() + u"Office math.docx"));

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

// Verify the size of the image that the OfficeMath object will create when we render it.
ASSERT_NEAR(122.0f, renderer->get_SizeInPoints().get_Width(), 0.25f);
ASSERT_NEAR(13.0f, renderer->get_SizeInPoints().get_Height(), 0.15f);

ASSERT_NEAR(122.0f, 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(119.5f, 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);
System::String dpi96 = u"DPI 96";
ASSERT_EQ(163, bounds.get_Width()) << (dpi96);
ASSERT_EQ(18, bounds.get_Height()) << (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);
System::String dpi96150 = u"DPI 96 150";
ASSERT_EQ(163, bounds.get_Width()) << (dpi96150);
ASSERT_EQ(27, bounds.get_Height()) << (dpi96150);

// The opaque bounds may vary here also.
bounds = renderer->GetOpaqueBoundsInPixels(1.0f, 96.0f);
System::String dpi96Opaque = u"DPI 96 Opaque";
ASSERT_EQ(160, bounds.get_Width()) << (dpi96Opaque);
ASSERT_EQ(19, bounds.get_Height()) << (dpi96Opaque);

bounds = renderer->GetOpaqueBoundsInPixels(1.0f, 96.0f, 150.0f);
System::String dpi96150Opaque = u"DPI 96 150 Opaque";
ASSERT_EQ(160, bounds.get_Width()) << (dpi96150Opaque);
ASSERT_EQ(29, bounds.get_Height()) << (dpi96150Opaque);
