It is used for road sign annotation etc.
|
|
|
|
First of all you need to select the `ellipse` on the controls sidebar.
|
|
|
|
|
|
|
|
Choose a `Label` and click `Shape` or `Track` to start drawing. An ellipse can be created the same way as
|
|
a {{< ilink "/docs/manual/advanced/annotation-with-rectangles" "rectangle" >}}, you need to specify two opposite points,
|
|
and the ellipse will be inscribed in an imaginary rectangle. Press `N` or click the `Done` button on the top panel
|
|
to complete the shape.
|
|
|
|
|
|
|
|
You can rotate ellipses using a rotation point in the same way as
|
|
{{< ilink "/docs/manual/advanced/annotation-with-rectangles#rotation-rectangle" "rectangles" >}}.
