# Eraser

## Overview

The Eraser is used to remove blocks of color from the current layer, selection, or image. If the Eraser is used on on the Background layer, the eraser will remove color areas and replace them with the current background color. If used on a normal floating layer, the color will be replaced with transparency. The same rules apply to non-alpha images.

## Eraser Tool Options

  The Incremental checkbox actiavtes incremental paint mode for the tool. More information about incremental mode can be found in the glossary
