If the fill overruns the lines, you

Tips 
•
To see how Fill Cell works, do the 
following:
1. Draw a black circle on a blank 
document. 
2. Select a new color.
3. Choose the Paint Bucket tool, and click 
the Fill Cell button on the property bar.
4. Click inside the circle.
5. Choose Edit menu > Undo.
6. Select another color.
7. Click outside the circle.
•
You can constrain the fill to a 
rectangular area by dragging with the 
Paint Bucket tool.
•
If you are recording your session as a 
script, cell fills are captured as well. When 
playing back at a different resolution, cell 
fills (and their limiting rectangles) are 
properly scaled. For information on 
recording and playing back sessions, refer 
to “Understanding Scripting” on 
page 415. For information on limiting 
rectangles, refer to “Limiting and 
Preventing Leakage” on page 121.
Limiting and Preventing 
Leakage
In complex drawings, lines don’t 
always meet. This can create fill leaks 
into areas you don’t want to be 
filled—sometimes through the whole 
image.
You can’t always tell if there’s a leak 
just by looking at your image. If you 
click a small area and see the prompt,
