The following settings can be adjusted using a vertical tool slider:
Opacity/Accumulation toggle—how see-through the brush is or the extent of deviation in the opacity or visibility of the stroke as it is painted, respectively. Tap to toggle the setting, then slide up or down to set the value.
Flow/Hardness toggle—how fast the brush effect is applied (1% is very slow, 100% is immediate) or how hard edged the brush is, respectively.
Width/Tolerance toggle—controls the width of the stroke using a vertical slider next to the tool's location or sets a tolerance that controls how dissimilar the pixels can be compared to the sampled pixel for the pixels to be erased. A low percentage affects only pixels very similar to the sampled pixel.The following settings can be adjusted from the context toolbar:
Continuous—if this option is off (default), samples the colour only once on the first tap. When selected, samples colour continuously as you drag.
Contiguous—when selected (default), affects neighbouring pixels as well as the sampled pixel colour. If this option is off, affects only the selected pixel colour.
Force Pressure—toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
