Paint Bucket controls

Adjust the following controls for the Paint Bucket effect:

Note: Paint Bucket has minimal impact on a solid layer.

Fill Point

Specifies the area of the image the effect fills with the new color. Depending upon where you place the effect point, the control samples between 1 and 4 pixels' RGB and alpha values and calculates an average value. This value determines which pixels to fill with the new color. How far the fill color spreads depends upon the specified Tolerance setting, as well as the option you choose in the Fill Selector menu.

Fill Selector

Specifies the channels to fill with the new color.

• Color & Alpha specifies that the effect fills the fill point's RGB and alpha channels with the new color.
• Straight Color specifies that the effect fills only the fill point area's RGB channel 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

Specifies the range of pixels that the effect fills with the new color. This value is based upon the option chosen in the Fill Selector menu. Higher values expand the range of similar pixel values that the effect fills. Lower tolerance values restrict that range.

View Threshold

Causes the effect to display the threshold values in black and white (based on the tolerance value) in the Composition window. The white areas within the tolerance range fill with the selected fill color. This is especially useful in tracking leaks. When there is a small gap, the color can flow over and fill areas not intended to be filled. If a leak is found, try reducing the Tolerance value or retouching your image, either by using the Paint effect or by editing the image in the application in which you created it.

Stroke

Specifies 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 just the border of the selected area. The Stroke Width value indicates the width of the stroke, in pixels.

Each of the options has a corresponding slider except for Antialias.

Invert Fill

Reverts all currently filled pixels to their original colors and transparency, and fills the previously unfilled pixels using the current settings.

Color

Specifies the color to use as the fill color.

Opacity

Specifies the transparency of the filled area.

Blending Mode

Specifies the blending mode the effect uses to create the operation between the new fill color and the original layer. All of these blending modes appear in the Mode menu in the Timeline window, except for Fill Only. Use Fill Only if you don't wish to composite the fill with the original image. Only the fill remains visible.

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 filter is displayed. The blending mode drops out the original image, thereby changing the fill point selection for the following applications of the filter.
