Paint Bucket effect

The Paint Bucket effect (formerly Basic Fill effect) is a nondestructive paint effect that fills an area with a solid color.

It works much like the Paint Bucket tool in Adobe Photoshop. Use the Paint Bucket effect for colorizing cartoon-type

outlined drawings or replacing areas of color in an image.

This effect works with 8-bpc color.

Fill Point The effect fills an area that contains the Fill Point. The area is determined by analyzing pixels that neighbor

the Fill Point and expanding the fill area by adding matching pixels. How far the fill color spreads depends upon the

Tolerance setting, as well as the option you choose from the Fill Selector menu.

Fill Selector Which values to operate on:

• 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.
