Fill Tool

Krita has one of the most powerful and capable Fill functions available. The options found in the Tool Options docker and outlined below will give you a great deal of flexibility working with layers and selections.

To get started, clicking anywhere on screen with the fill-tool will allow that area to be filed with the foreground color.

Tool Options

Fast Mode

This is a special mode for really fast filling. However, many functions don’t work with this mode.

Threshold

Determines when the fill-tool sees another color as a border.

Grow Selection

This value extends the shape beyond its initial size.

Feathering Radius

This value will add a soft border to the filled-shape.

Fill Entire Selection

Activating this will result in the shape filling the whole of the active selection, regardless of threshold.

New in version 4.4:

Use selection as boundary

When checked, this will count the borders of the selection as an extra boundary on top of the pixel difference.

Left: Original selection with a line. Middle: Filled with ‘use selection as boundary’ off. Right: Filled with ‘use selection as boundary’ on.

Use Pattern

Ticking this will result in the active pattern being used.

Rotation

New in version 4.4.

This allows you to rotate the pattern used in the fill.

Scale

New in version 4.4.

This allows you to scale the pattern used in the fill.

Sample

New in version 4.3.

Select which layers to use as a reference for the fill tool. The options are:

Current Layer

Only use the currently selected layer.

All layers

Use all visible layers.

Color Labeled Layers

Use only the layers specified with a certain color label. This is useful for complex images, where you might have multiple lineart layers. Label them with the appropriate color label and use these labels to mark which layers to use as a reference.

Labels Used

New in version 4.3.

Used with the ‘Color Labeled Layers’ option above.
