Bug

So using the latest version of X anylabeling

If I have existing rotated box annotations like this:

and then I go to resize a box by grabbing one of its corners like this:

The whole box kinda jumps or rotates randomly. The only difference between the above photo, and the one below is i clicked and started dragging the corner circled in red.

Sometimes the shape is even weirder. Needless to say it's a pretty frustrating bug.

Sorry, but I’m unable to reproduce the issue you’re experiencing. As a suggestion, please ensure that the rotation shapes itself is valid. For instance, if the data was imported from an external model or a label file, it might result in distortion when dragging, as the coordinate format may not comply with X-AnyLabeling’s specifications.

If possible, please record a video demonstrating the entire process from the beginning, rather than sharing a single screenshot, as a screenshot alone cannot provide enough context to identify the problem.

I do think it only comes from data that was created externally, so I think you are right! I figured since the box renders correctly, they would be compatible, but once the box is moved, it shifts. Is there a reference for X-anylabeling's specifications?

Hey there! @quithmeyer,

It seems to occur because quad-type shapes (e.g., irregular quadrilaterals) are being defined as rotation types. While these shapes may sometimes visually resemble rotated bounding boxes, their underlying coordinate definitions differ.

quad shapes usually rely on explicit corner coordinates. When these quad shapes are treated as rotation types, transformations like dragging or resizing may result in unexpected shifts or distortions due to the mismatched assumptions about how the geometry is calculated.

For example, in OCR tasks like ocr_with_region, people usually define quad types. However, if these are mistakenly set as rotation types, it can cause distortions when dragging. Therefore, please ensure that the data you import or the results obtained through model inference comply with the standards for rotated boxes. To debug this, you can write a simple script to check the relationships between the coordinate points.

Let me know if further clarification is needed! 😊
