Healing Brush Tool

The following settings can be adjusted from the context toolbar:

Width—the brush (stroke) size in pixels.
Opacity—how see through the brush is.
Flow—how fast the brush effect is applied (1% is very slow, 100% is immediate).
Hardness—how hard the edges of the brush are. The brush appears softer as the percentage decreases.
More—tap to display the Brushes dialog to access advanced brush settings.
Rotation—sets the degree of rotation applied to the sample.
Scale—sets the scale of the sample between 1% and 1000%. Type directly in the text box or drag the pop-up slider to set the value. The result can be previewed inside the brush cursor.
Force Pressure—Toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
Aligned—when selected (default), the origin of the sample remains a fixed distance from the pointer. If this option is off, the origin of the sample always returns to the sample location defined initially.
Flip—allows for horizontal and vertical flipping of the resulting healing area relative to the sampled area. Choose horizontal, vertical or both directions from a pop-up menu.
Source—the source determines the layer(s) from which the pixels are sampled. Select from the pop-up menu.
Continue Last—(on-screen modifier key) when pressed, laid-down healed areas are conjoined.
Set Source—(on-screen modifier key) sets the healing source as a key press as you continue healing.
