⚙️Annotation shapes
When working with videos, there are specific buttons available only for video-related functions. For more information go to Video annotation section.
The following functions are common to all classes of objects:
Icon | Function | Description |
---|---|---|
Delete the object completely ( | Deletes the annotation completely | |
Bind ( | Binds objects to each other, in the pattern Parent > Child | |
Redraw ( | Redraws the existing object | |
Change the Stacking order | Changes the order in which objects are displayed if their annotation boundaries are overlapped: Bring to front; Send to back; Place in front of object; Place behind object A detailed application of the Stacking order can be found here | |
Select | This tool is automatically activated when no other tool (like “Move” or “Edit”) is active. While the “Select” tool is active, no modifications are made to the selected object, and the left mouse button may be used to select objects in the editor. While other tools are active, objects may be selected using the | |
Edit ( | Edits the selected object | |
Change the type | Changes the type (class) of the annotated object |
When annotating objects in a video file, it's important to start from the first frame of appearance. Even if the object has a better angle at the end of the file, interaction occurs from previous to next (unless otherwise specified in the project instructions).
Object selection
To select multiple objects, press and hold the left mouse button anywhere in the editor window and then drag the pointer to draw the selection frame. Every object completely contained in the selection frame will be selected.
Alternatively, you can click an object (both in the editor window and in objects list) with the left mouse button while holding down the Ctrl
key to add it to the selection or, if already selected, to unselect it.
Finally, drawing the selection frame while holding down the Ctrl
key will add all the objects that are completely contained in the frame to the current selection instead of replacing the current selection (if all objects contained in the frame are already selected, they will be removed from the selection instead).
Image rotation
It is possible to rotate the image in the editor, which may be useful for images that were taken by a tilted camera. To rotate image in the editor:
Hold down the
ctrl and alt keys
, then click and hold the left mouse button on the point around which you want to rotate the viewport. A dotted circle will appear around the point you've clicked.
Move the mouse pointer out of the circle. Now the circle becomes solid, and you can move the mouse pointer around it to rotate the image.
The rotation will be restricted to 15 degrees increments while you're holding down the
Ctrl
key. Release theCtrl
key to rotate to an arbitrary angle.
Object annotation can be divided into classes:
In addition to button usage, Shortcut keys are also available on the platform.
