Maintains the original layer's alpha channel. If you choose Including Alpha in the Average

Pixel Color menu, the original alpha is stenciled over the sampled color.
The effect's transparency. The result of the effect is blended with the original image, with the
Blend With Original
effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you
set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn't
show through.
Fill effect
The Fill effect fills specified masks with a specified color. If you want to add both a stroke and a fill to a closed path,
the order in which you apply the stroke and fill determines the visible width of the stroke: If the fill is applied before
the stroke, the full stroke brush size is visible; if the stroke is applied before the fill, the fill appears on top of the stroke,
obscuring the half of the stroke that falls inside the path.
This effect works with 8-bpc color.

Fractal effect
The Fractal effect renders the Mandelbrot or Julia set, creating colorful textures. When you first apply the effect, the
picture you see is the classic sample of the Mandelbrot set; the set is the area that is colored black. Any pixel outside
the set is colorized, depending on how close it is to the set.
This effect works with 8-bpc and 16-bpc color.

set mathematically inverted. Julia always changes depending on the center point from the Mandelbrot set and can
produce the set of all possible Julia sets. Julia Inverse is the inverse of the Julia set. To see a Julia set, you may want to
set the magnification to a negative value, because these sets tend to fill up the complex plane outside the normal
boundary. Mandelbrot Over Julia is the same as Mandelbrot, except that it does change when the Julia center point
changes. Mandelbrot Inverse over Julia is the same as Mandelbrot Inverse, except that it does change when the Julia
center point changes.
