Using the eraser tool
The eraser tool changes pixels in the image as you
drag through them. If you're working in the
background, or in any other layer with Preserve
Transparency on, the pixels change to the
background color (see "Choosing the foreground
and background colors" on page 214). Otherwise,
transparency replaces the color. You can also use
the eraser to return the affected area to a state
selected in the History palette.
Erasing pixels from layer exposes underlying layer.
To use the eraser tool:
Double-click the eraser tool to display its
1
Options palette.
