The pen’s thickness, alpha, and colour can be adjusted before and after annotating. Prior to annotating, use the Pen Tool’s properties box to adjust:
After annotating, select the object, and the properties box will reappear with additional options:
- Bring Forwards
- Send Backwards
- Mirror Horizontally
- Mirror Vertically
- Lock in place
