The outline toggle adds edge detection to your simplified image, drawing lines around each value shape. This makes it easier to see the distinct shapes and plan your painting.
How it works
When activated, the app analyzes your simplified image and draws outlines around areas where values change. You can turn this on or off depending on whether you want to see clean shapes or defined edges.
Why it's useful
Showing outlines helps you:
- See value shapes more distinctly
- Transfer compositions to your canvas more easily
- Understand the abstract pattern of your image
- Create clearer reference images for painting
Tips for use
Try simplifying your image to 3-4 values and then turning on outlines. This creates a paint-by-numbers style reference that's perfect for planning watercolors or other media where you work from light to dark.
