Matplotlib: How to scale/multiply Bbox by a scalar (float)

In order to scale a Bbox object by a scalar, you can use a Affine2D transformation. Here’s how you can do it:

# Example scale factor
scale = 300.0

# Create an example bbox
bbox = Bbox.from_bounds(0, 0, 1, 1)

# Create the scale transformation
import matplotlib.transforms as transforms
scale_transform = transforms.Affine2D().scale(scale)

# Example usage
scaled_bbox = bbox.transformed(scale_transform)
