Flash Tip: Program Tools: Paint Bucket Tool

The options for the Paint Bucket tool control just how "tolerant" the flood fills are. If you set it to Don't Close Gaps, then the Paint Bucket Tool will only work to fill completely enclosed areas of a shape (that is, shapes that are completely bounded by a line with no broken spaces). But if you set it to Close Small Gaps, it will ignore small breaks in the bounding lines to fill the enclosed area. Close Medium Gaps and Close Large Gaps will cause the Paint Bucket tool to ignore larger and larger spaces in the bounding lines to treat them as enclosed areas.
