As we were trying to label the data on the label studio we faced this issue

To Reproduce Steps to reproduce the behavior:

1. Draw labels
2. Click on export the labels in VOC XML
3. when the labels are exported we just try to plot them on the image to validate the bounding boxes Expected behavior As per the expected behavior we would see that the bounding box is drawn on the object according to label studio but the the bounding boxes has been outside of the object causing the accuracy and object detection to failed.

Screenshots

Environment (please complete the following information):

• OS: - windows 11

Hello,

Thank you for the message! I was referring to the actual label configuration in XML format. Nonetheless, just to clarify how rotation works when you're labeling in Label Studio:

When you rotate a bounding box using your mouse in the labeling interface, the center of the rectangle acts as the anchor point for the rotation. This means the box spins around its own center — not from a corner or edge.

You can refer to the illustration found in this link for a visual explanation:

Thank you!
