Display Shapes
This section of the menu contains helpful tools for adjusting how the image and shapes are displayed
 |
|
| If your workspace has many shapes on it, these three options can be extremely helpful for removing visual clutter while you work. |
View Settings
 |
| View settings allow you to personalize how shapes are displayed in the workspace. These settings are just for the workspace and aren't saved with the task when submitted. |
Opacity
 |
Increases or decreases the opacity of shapes so that you can see less or more of the image behind. 📘 Note Return to the default opacity by clicking the undo button next to the slider. Use case
|
Point Size
 |
With this tool, you can easily select a pixel size from 1px to 5px. 📘 Note Return to the default points size by clicking the undo button next to the slider. Use case
|
Intensity
Intensity allows you to target your intensity color pallets, making it possible to enhance the color pallet for ground reflective objects.
Intensity values represent how “reflective” the surface of an object is. When it is reflective, like a traffic sign, the values will be on the “High spectrum”. When they have low reflectivity, the values will be on the “Low spectrum”.
 |
Click on the view settings menu. You can define the minimum and maximum intensity values you would like your intensity pallet to be applied. You can play with ranges to find the object you are looking for! 📘 Note Return to the default intensity by clicking the undo button next to the slider. Use case

Keyboard shortcuts
 |
This button displays a pop-up cheat sheet of all the available keyboard shortcuts for easy reference. 👍 Tip Use keyboard shortcuts whenever possible to save time when annotating. Annotators who use keyboard shortcuts for all their repetitive tasks are substantially more efficient than annotators who rely on a mouse. |
