Allow Oriented Bounding Boxes to go out of the image margin

[ViktorYu234]

Hello,

I am utilizing Label Studio at my work and one of my tasks is it to label rotated rectangles in my images. For this task I'm utilizing Oriented Bounding Boxes. But there's one issue in Label-Studio which prevents me from doing my task properly:

Label-Studio does not allow OBB to go out of the image margin

This is an issue for me because sometimes there are rectangles which partially go out of bounds, forcing me to either mark them as a not oriented BB or to make them appear smaller as they actually are. But both solutions are rather bad for me because they may confuse the AI which needs to learn to mark even them properly.

Take this image as an example:

The minimal size of the rectangle can be determined as marked in the image, but labeling it properly is impossible without going out of the margin. I need to either not use oriented BB and include a big part of the background and mark it as not rotated, or make the labeled area smaller than it actually is (the label marked in the image doesn't even cover 1/3 of the actual rectangle).

I would like to be able to place at least one corner of the labeled area per image side out of the image margin to allow me to deal with issues like I described (Or rather in a way that each side of the label can't go fully out of image margin, but that might be not enough for other users who work with fully identical rectangles going out of bounds or so).

Actually I do not need an immediate update which implements this feature. If somebody can tell me the location of the code snippet which prevents me from moving my OBB out of bounds, I could change it for me by myself which would also be enough for me.

Can anyone help me?
