size_in_points property

NodeRendererBase.size_in_points property

Gets the actual size of the shape in points.

@property
def size_in_points(self) -> aspose.pydrawing.SizeF:
    ...

Remarks

This property returns the size of the actual (as rendered on the page) bounding box of the shape. The size takes into account shape rotation (if any).

Examples

Shows how to measure and scale shapes.

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(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)

# Get the shape size in pixels, but with a different DPI for the horizontal and vertical dimensions.

dpi96150 = 'DPI 96 150'
