Erase Brush ToolYou can erase from any area of a pixel layer using the Erase Brush Tool. Erased pixels become transparent. If the brush is used on a vector object or layer, a mask is automatically created and the erasing will be performed non-destructively.
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—controls the width of the stroke using a vertical slider next to the tool's location. Slide up or down to set the width.The following settings can be adjusted from the context toolbar:
Force Pressure—toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
For rope mode—drag the stroke end by a 'rope' to smooth the stroke but introduce sharp corners at increasing rope Length (radius) values by redirecting the slackened rope. Set the value by toggling the Length vertical slider icon. For window mode—smooths the stroke by averaging sampled input positions within a Window whose size is configurable. Set the value by toggling the Width vertical slider icon.
Symmetry—when the Lines setting is set to greater than 0, repeats the brush stroke around a number of axes (defined by the value). The centre axis point can be repositioned by dragging it.
Mirror—with symmetry enabled, causes brush strokes to be mirrored along the X and Y axis.
Locked—when enabled, prevents the symmetry line from being moved.
