Normally the MacPaint bucket allows for a single filling of a bounded area of a shape. If you wish to try various fills to see which looks best, select Undo on the Edit Menu after each fill.
The May 1984 Version 1.3 of MacPaint has a new Fill command on the Edit Menu. To use it, lasso an object and select Fill. The active fill pattern at the bottom of the palette will fill the entire object. There are no limitations on the number of times an object may be filled. The bucket still has its original limitations.
Often there is the need to put one outline shape on top of another and to have both shapes filled with the same pattern. This helps you to position objects and text, providing a "stop" every eight fatbits. The smallest square that may be created while the grid is active is nine by nine fatbits. Unlike the grid in LisaDraw, this grid is invisible and nonadjustable.
