# Bucket Fill

## Overview

The Bucket Fill tool is used to fill areas of a layer or selection with either color or a pattern.

## Bucket Fill Tool Options

Bucket Fill Settings

Opacity

  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.

Mode

  The Mode dropdown list provides a selection of paint application modes. A list of these modes can be found in the glossary.

Sample Merged

  This option 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.

Threshold

  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.

Fill Type

  - FG Color Fill: This sets the fill color to the currently selected foreground color.

  - BG Color Fill: This sets the fill color to the currently selected background color.

  - Pattern Fill: This option sets the fill color to the currently selected pattern.
