get_bounds_in_pixels method

get_bounds_in_pixels(scale, dpi)

Calculates the bounds of the shape in pixels for a specified zoom factor and resolution.

def get_bounds_in_pixels(self, scale: float, dpi: float):
    ...

Parameter	Type	Description
scale	float	The zoom factor (1.0 is 100%).
dpi	float	The resolution (horizontal and vertical) to convert from points to pixels (dots per inch).

Remarks

This method converts NodeRendererBase.bounds_in_points into rectangle in pixels.

Returns

The actual (as rendered on the page) bounding box of the shape in pixels.

get_bounds_in_pixels(scale, horizontal_dpi, vertical_dpi)

Calculates the bounds of the shape in pixels for a specified zoom factor and resolution.

def get_bounds_in_pixels(self, scale: float, horizontal_dpi: float, vertical_dpi: float):
    ...

Parameter	Type	Description
scale	float	The zoom factor (1.0 is 100%).
horizontal_dpi	float	The horizontal resolution to convert from points to pixels (dots per inch).
vertical_dpi	float	The vertical resolution to convert from points to pixels (dots per inch).

Remarks

This method converts NodeRendererBase.bounds_in_points into rectangle in pixels.

Returns

The actual (as rendered on the page) bounding box of the shape in pixels.

Examples

Shows how to measure and scale shapes.

doc = aw.Document(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(119.0, renderer.size_in_points.width, delta=0.25)
self.assertAlmostEqual(13.0, renderer.size_in_points.height, delta=0.1)

self.assertAlmostEqual(119.0, renderer.bounds_in_points.width, delta=0.25)
self.assertAlmostEqual(13.0, renderer.bounds_in_points.height, delta=0.1)

# Shapes with transparent parts may contain different values in the "opaque_bounds_in_points" properties.
self.assertAlmostEqual(119.0, 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(1.0, 96.0)

self.assertEqual(159, bounds.width)
self.assertEqual(18, bounds.height)

# Get the shape size in pixels, but with a different DPI for the horizontal and vertical dimensions.
bounds = renderer.get_bounds_in_pixels(1.0, 96.0, 150.0)
self.assertEqual(159, bounds.width)
self.assertEqual(28, bounds.height)

# The opaque bounds may vary here also.
bounds = renderer.get_opaque_bounds_in_pixels(1.0, 96.0)

self.assertEqual(159, bounds.width)
self.assertEqual(18, bounds.height)

bounds = renderer.get_opaque_bounds_in_pixels(1.0, 96.0, 150.0)

self.assertEqual(159, bounds.width)
self.assertEqual(30, bounds.height)
