Using the magic eraser tool

When you click in a layer with the magic eraser tool, the tool automatically changes all similar adjacent pixels. If you're working in the background, or in a layer with locked transparency, the pixels change to the background color; otherwise, the pixels are erased to transparency. You can choose to erase contiguous pixels only or all similar pixels on the current layer.

To use the magic eraser tool:

1 Select the magic eraser tool ().

2 Enter a tolerance value. This defines the range of colors that can be erased. A low tolerance erases pixels within a range of color values very similar to the pixel you click. A high tolerance erases pixels within a broader range.

3 Select Anti-aliased to smooth the edges of the area you erase.

4 Select Contiguous to erase only pixels contiguous to the one you click, or leave unselected to erase all similar pixels in the image.

5 Select Use All Layers to sample the erased color using combined data from all visible layers.

6 Specify an opacity to define the strength of the erasure. An opacity of 100% erases pixels to complete transparency. A lower opacity erases pixels to partial transparency.

7 Click in the part of the layer you want to erase.
