Bucket Fill
The Bucket Fill tool is used to fill areas of a layer or selection with either color or a pattern.
Bucket Fill Tool Options
-----------------------------------
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.
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: This sets the fill color to the currently selected foreground color.
BG Color: This sets the fill color to the currently selected background color.
Texture: This sets the fill color to the currently selected texture.
Transparent: This sets the fill color to transparent color.
Graident Fill
The Graident Fill tool renders a gradient based on the current foreground and background colors. The start and end points are set using the mouse. Simply drag and drop a line, and the gradient will be rendered using the foreground color as the start and the background color as the end.
Graident Fill tool Options
------------------------------------
Opacity
The Opacity slider sets the transparency level for the blend. A higher opacity setting results in a more opaque blend and a lower setting results in a more transparent blend.
Mode
The Mode dropdown list provides a selection of blend application modes.
Color
FG to BG: Renders the gradient using the foreground color and background color.
Custom Gradient: Renders the gradient using the currently selected gradient.
FG to Transparent: Renders the gradient using the foreground color and fades that color into transparent over the length of the gradient.
Transparent to FG: Renders the gradient using the transparent and fades that into foreground color over the length of the gradient.
Gradient
Linear: Maps the rendered gradient along a linear path directly from start to end. This is the default behavior.
Radial: Maps the gradient in a circle. The start point for the gradient represents the center of the circle and the end point marks the radius. The colors are rendered such that the gradient fades from the center of the circle to the outer edge, from foreground to background.
Square: Maps the gradient as a square. The gradient will always be rendered as a perfect square with the sides facing left, up, right, and down. The start point sets the center of the square and the end point sets the outer edge of the square.
Conical (symmetric): Creates a gradient that is mapped to a circle. The gradient is rendered around the start point which represents the anchor around which the render takes place. The unseen line between the start and end points sets the start of the gradient. Directly opposite this is where the gradient is completed and reversed creating a conical effect.
Conical (asymmetric): Creates a gradient similar in detail to the Conical (symmetric) one, but the gradient is not reversed at the half-way point.
Shapeburst: Maps the layer or selection shape prior to rendering the gradient. The resulting effect is based on that shape.

Gradient
The Gradient setting toggles the use of the currently selected gradient in stead of the current foreground color. There are four ways that the gradient can be rendered.
Once Forward: Renders the gradient once during the stroke. It is painted in a forward direction. The entire color sequence of the gradient will be rendered within the distance set.
Once Backward: Renders the gradient once during the stroke. It is painted in a reverse order of colors. The entire color sequence of the gradient will be rendered within the distance set.
Loop Sawtooth: Renders the gradient repeatedly. At each expiry of the distance that has been set, the gradient will begin rerendering from the beginning.
Loop Triangle: Renders the gradient repeatedly. At each expiry of the distance that has been set, the gradient will reverse direction and render in that direction until the expiry of the distance once more. At this point, it will begin again until the stroke is complete.
