Erasing image areas

You can edit images and objects by erasing areas. For example, you can erase part of an object to change its shape or reveal more of the layer below. You can also erase areas of the image to reveal the background color, or erase part of the last action applied to the image.

The tools used to erase have many of the same settings as brushes, which means you can control the size, shape and transparency to create unique effects. For example, you can apply a bitmap fill to the entire image, increase the transparency value of the eraser tool, and create a superimposed effect by partially erasing the fill (the last action performed).

You can also erase image areas based on color. The background color replaces the foreground color you erase.

To erase part of an object

1 Select an object.

2 Click the Eraser tool j .

3 Specify the settings you want on the property bar.

The erased areas reveal the object below.

To maintain the shape of an object, enable the Lock object transparency button p on the Objects Docker window/palette. If the Objects Docker window/palette is not open, click Window ► Dockers / Palettes ► Objects.
