When creating a dataset through the Python SDK, choose vector or image-vector-sequence as the task_type to use this labeling interface.
To add a new object:
Select an annotation type (see Annotation types)
Label the object by drawing on the image
Press Space or Escape or click the button in the left toolbar to enter view-and-select mode
Click on a labeled object to select it. You can also select an object by selecting it in the right sidebar
Select an object and press Backspace to remove it. You can also click the icon in the sidebar to remove an object.
Select an object and click on its name in the sidebar to select a different category. You can also use hotkey c to change the category of the active object.
To make it easy to draw shapes closely together you can just draw overlapping bounding boxes and polygons. If you then select one of the overlapping shapes you can press the hotkey (default r ) to intersect the active shape with the other shapes it overlaps with.
After finishing a polygon, you can add a point to it with Shift + left click. This will add a point to the edge closest of the cursor. You will see a preview of where the point will be added as soon as you press Shift. You can add points to a selected polygon in view-and-select mode, or while still in draw polygon mode after finishing it.
You can remove a point by Shift + left click. A polygon needs at least 3 points.
When holding Shift + Fnode snapping is activated. This will snap the point you want to add to the nearest handle of an existing vector, within a certain distance threshold.
After finishing a polyline, you can add a point to it with Shift + left click. This will add a point to the edge closest of the cursor. You will see a preview of where the point will be added as soon as you press Shift. You can add points to a selected polyline in view-and-select mode, or while still in draw polygon mode after finishing it.
You can remove a point by Shift + left click. A polyline needs at least 2 points.
When holding Shift + Fnode snapping is activated. This will snap the point you want to add to the nearest handle of an existing vector, within a certain distance threshold.
Click in the interface to set the first point
Move your cursor to another point and it will display the measurement in pixels
