Eraser

If you use the eraser tool on the background layer, the erased pixels are painted to match the background color. If you use the eraser tool on any other layer, the erased pixels are made transparent. The eraser tool adopts the parameters in the brush settings in the Active Tool manager, including filters.

In projection painting mode, the eraser affects the projected layer only (see Projection Painting).
