Change similar pixels with the Magic Eraser tool
When you click in a layer with the Magic Eraser tool, the tool changes all similar pixels to transparent. If you’re working in a layer with locked transparency, the pixels change to the background color. If you click in the background, it is converted to a layer and all similar pixels change to transparent.
You can choose to erase contiguous pixels only or all similar pixels on the current layer.
- Enter a tolerance value to define 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 extends the range of colors that will be erased.
- Select Contiguous to erase only pixels contiguous to the one you click, or deselect to erase all similar pixels in the image.
