Artistic Eraser
The Artistic Eraser 
erases an image on the selected artistic layer. This tool changes the transparency of pixels and removes the relief of paint. Press E to quickly access this tool.
The tool's parameters will be shown in a floating box over an image (by right-clicking the mouse) and also in the Settings Panel.
To change the setting of a parameter, enter a numerical value in its box and press enter Enter (Mac: Return) or move the slider.
- Size (1-300). The maximum width of a line the tool erases (in pixels).
-
Strength (0-100). The impact of the tool on an image. The higher the value, the greater the change in transparency of pixels. At low values only the relief of an image is erased.
