Fix RotatedBbox.wrap() by assigning correct attributes

[williamcorsel]

The RotatedBbox.wrap() function tries to access wrong attributes. This causes errors in dataset transforms that include rotated bounding boxes. See the example:

"""Minimal reproducible example demonstrating the bug in RotatedBbox.wrap method.

The wrap method tries to access item.x and item.y, but RotatedBbox only has
cx and cy properties (center coordinates), not x and y.
"""

from datumaro.components.annotation import RotatedBbox

bbox = RotatedBbox(cx=100.0, cy=200.0, w=50.0, h=30.0, r=45.0, label=0)
wrapped_bbox = bbox.wrap(label=1)

Pull request overview

This pull request fixes a bug in the RotatedBbox.wrap() method that was attempting to access incorrect attributes (x and y instead of cx and cy). The RotatedBbox class uses center coordinates (cx, cy) rather than top-left coordinates like the Bbox class, and the wrap method needs to correctly reference these attributes.

Key Changes

• Updated RotatedBbox.wrap() to use cx and cy (center coordinates) instead of the non-existent x and y attributes
