Color & Alpha Specifies that the effect fills the RGB and alpha channels of the fill area with the new color.
Straight Color Specifies that the effect fills only the RGB channels of the fill area with the new color.
Transparency Specifies that the effect fills only the transparent areas near the fill point. You must set a fill point in a transparent area for
this option to work.
Opacity Specifies that the effect fills only the opaque areas near the fill point. You must set a fill point in an opaque area for this option to
work.
Alpha Channel Specifies that the effect fills either the opaque or transparent areas in the whole image, depending upon the alpha
channel value at the point you set the fill point.
Tolerance How far the color values of a pixel can be from the Fill Point color values and still match. Higher values expand the range of pixels that
the effect fills.
View Threshold Shows what pixels match—that is, which pixels are within the Tolerance value of the color values of the Fill Point pixel. This
option is especially useful in tracking leaks. If a small gap exists, the color can flow over and fill areas not intended to be filled.
Stroke How the effect treats the edges of the filled area:
Antialias Anti-aliases the edges of the filled area.
Feather Creates a feathered edge for the filled area. Feather Softness values create a more gradually disappearing edge.
Spread Expands the area of the fill color. The Spread Radius value indicates the number of pixels the fill color extends beyond the edge
of the fill area.
Choke Contracts the area of the fill color. The Spread Radius value indicates the number of pixels the fill color shrinks from the edge of
the fill area.
Stroke Confines the fill to only the border of the selected area. The Stroke Width value indicates the width of the stroke, in pixels.
Color The fill color.
Opacity Opacity of the filled area.
Blending Mode The blending mode to use to composite the result of the effect on top of the original layer. All of these blending modes operate
like the blending modes in the Timeline panel, except for Fill Only. Use Fill Only to show only the fill.
Note: If you apply multiple instances of Paint Bucket to a layer, be sure not to set more than one to use the Fill Only blending mode. If you set
more than one instance to use this blending mode, only the first application of the effect is shown.
Radio Waves effect
The Radio Waves effect creates radiating waves from a stationary or animated effect control point. You can use this effect to generate pond
ripples, sound waves, or intricate geometric patterns. Use the Reflection control to make the shapes bounce off the sides of the layer. You can
also use Radio Waves to create realistic wave displacement maps that work well with the Caustics effect.
Satya Meka provides a video tutorial and some tips for using the Radio Waves effect on his website . Satya demonstrates animation of the mask
that the radio wave shape is based on. He also demonstrates that you can get smooth, organic contours (rather than discrete waves) by using a
very high value for Frequency, together with carefully chosen Fade-in Time and Fade-out Time settings.
This effect works with 8-bpc color.
Polygon wave type with square stroke profile (lower-left), and Image Contour wave type with Sine stroke profile (lower-right)
Producer Point The point from which the waves appear.
Parameters Are Set At Specifies whether parameters can be animated for individual waves. Birth specifies that each wave maintains the same
parameter settings over time. Each Frame specifies that the waves change as the parameters change. For example, if you create a star wave with
an animated rotation property, select Birth to offset each star from the previous one to create a twisting tunnel, or select Each Frame to make all
the stars rotate in unison as the rotation property changes.
Render Quality Controls the quality of the output. Radio Waves creates smooth, anti-aliased shapes by rendering high-resolution versions of the
shapes and then scaling them down by oversampling. For example, to create a 100x100-pixel image, it may generate a 400x400-pixel image and
then scale it down using 4x oversampling. Oversampling provides high-quality results but results in long render times. This option works only with
Best quality mode.
