Common Uses for Pen and Eraser
After analyzing your frames, you may find gaps in your linework. In addition to adjusting the Analysis Settings, you can use the pen and eraser to make manual corrections. You can also use the pen on the Color Layer for small tweaks. Note that drawing on the color layer does not currently update the segmentation mask, so manual changes may not persist through re-colorization.Fill Tool
