## 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/python-net/working-with-officemath/) documentation article.




**Inheritance:** [OfficeMathRenderer](./) → [NodeRendererBase](../noderendererbase/)

### Examples

Shows how to measure and scale shapes.

```python
doc = aw.Document(file_name=MY_DIR + 'Office math.docx')
office_math = doc.get_child(aw.NodeType.OFFICE_MATH, 0, True).as_office_math()
renderer = aw.rendering.OfficeMathRenderer(office_math)
# Verify the size of the image that the OfficeMath object will create when we render it.
self.assertAlmostEqual(122, renderer.size_in_points.width, delta=0.25)
self.assertAlmostEqual(13, renderer.size_in_points.height, delta=0.15)
self.assertAlmostEqual(122, renderer.bounds_in_points.width, delta=0.25)
self.assertAlmostEqual(13, renderer.bounds_in_points.height, delta=0.15)
# Shapes with transparent parts may contain different values in the "OpaqueBoundsInPoints" properties.
self.assertAlmostEqual(119.5, renderer.opaque_bounds_in_points.width, delta=0.25)
self.assertAlmostEqual(14.2, renderer.opaque_bounds_in_points.height, delta=0.1)
# Get the shape size in pixels, with linear scaling to a specific DPI.
bounds = renderer.get_bounds_in_pixels(scale=1, dpi=96)
dpi96 = 'DPI 96'
self.assertEqual(163, bounds.width, msg=dpi96)
self.assertEqual(18, bounds.height, msg=dpi96)
# Get the shape size in pixels, but with a different DPI for the horizontal and vertical dimensions.
bounds = renderer.get_bounds_in_pixels(scale=1, horizontal_dpi=96, vertical_dpi=150)
dpi96150 = 'DPI 96 150'
self.assertEqual(163, bounds.width, msg=dpi96150)
self.assertEqual(27, bounds.height, msg=dpi96150)
# The opaque bounds may vary here also.
bounds = renderer.get_opaque_bounds_in_pixels(scale=1, dpi=96)
dpi_96_opaque = 'DPI 96 Opaque'
self.assertEqual(160, bounds.width, msg=dpi_96_opaque)
self.assertEqual(19, bounds.height, msg=dpi_96_opaque)
bounds = renderer.get_opaque_bounds_in_pixels(scale=1, horizontal_dpi=96, vertical_dpi=150)
