Filling a region

Filling regions or layers is an alternative to brushing on colors or patterns.

Making a selection prior to applying a fill, and setting appropriate options, can

spell the difference between a humdrum effect and a spectacular one.

The Fill Tools flyout on the Tools toolbar includes two tools for filling

regions with color and/or transparency: Flood Fill and Gradient Fill. In

addition, you can use the Edit>Fill... command to apply either a color or

pattern fill. As with paint tools, if there is a selection, the Fill tools only affect

pixels within the selected region. If you’re operating on a shape or text layer, a

single fill affects the interior of the object(s) on the layer.

Flood and pattern fills

The Flood Fill Tool works on Background and standard layers, replacing

an existing color region with the foreground color. How large a region is

"flooded" with the fill color depends on the difference between the color of the

pixel you initially click and the color of surrounding pixels.

To use the Flood Fill Tool:

1. Select the Flood Fill Tool from the Tools toolbar's Fill Tools flyout.

2. Set tolerance and layer fill options on the Context toolbar.

You can use the Context toolbar to set a tolerance value—how much

of a color difference the tool looks for. With a low tolerance setting,

the tool "gives up easily" and only fills pixels very close in color to the

one you click (a setting of 0 would fill only pixels of the same color;

255 would fill all pixels). As the tolerance increases, so does the tool's

effect on pixels further in color from the original pixel, so a larger

region is flooded.

When Antialias is checked, the boundary of a color fill is smoothed;

uncheck to produce a hard edge to the fill boundary.

When checked, Contiguous affects only pixels connected to the

clicked pixel; uncheck to affect in-range pixels throughout the region.
