<p>
This tool fills a selection with the current foreground color. If
you Shift+click and use the Bucket tool, it will use the
background color instead. Depending on how the tool options are
set, the Bucket Fill tool will either fill the entire selection,
or only parts whose colors are similar to the point you click on.
The tool options also affect the way transparency is handled.
</p>
<p>
The amount of fill depends on what Fill Threshold you have
specified. The fill threshold determines how far the fill will
spread (similar to the way in which the magic wand works). The
fill starts at the point where you click and spreads outward until
the color or alpha value becomes "too different."
</p>
<p>
When you fill objects in a transparent layer (such as letters in a
text layer) with a different color than before, you may find that
a border of the old color still surrounds the objects. This is due
to a low fill-threshold in the Bucket Fill options dialog. With a
low threshold, the bucket tool won't fill semi-transparent pixels,
and they will stand out against the fill because they have kept
their original color. If you want to fill areas that are totally
transparent, you have to choose right-click|Select|Select All, and
make sure that the layer's "Keep Transparency" button (in the Layers
dialog) is unchecked. If the Keep Transparency button is
checked, only the opaque parts of the layer will be filled, and if
you don't use the Select All command, only the opaque "island"
that you clicked on will be filled.

The Opacity slider sets the transparency level for the fill. A
higher opacity setting results in a more opaque fill and a lower
setting results in a more transparent fill.

<span class="guilabel">Pattern Fill</span>.
</p>
<p>
<span class="guilabel">FG Color Fill</span> sets the fill color to the
currently selected foreground color.
</p>
<p>
<span class="guilabel">BG Color Fill</span> sets the fill color to the
currently selected background color.

The option <span class="guilabel">Sample Merged</span> toggles the
sampling from all layers. If Sample Merged is active, fills can
be made on a lower layer, while the color information used for
threshold checking is located further up. Simply select the lower
level and ensure that a layer above is visible for color
weighting.
</p>
<p>
The Threshold slider sets the level at which color weights are
measured for fill boundaries. A higher setting will fill more of
a multi colored image and conversely, a lower setting will fill
less area.
