Eraser
The Eraser tool
erases content based on the active layer. If the user is on the text layer,
then any text across which the tool is dragged will be erased. The eraser will
convert the pixels to transparent, unless the background layer is selected. The
size and style of the eraser can be selected in the options bar. This tool is
unique in that it can take the form of the paintbrush and pencil tools. In
addition to the straight eraser tool, there are two more available options –
background eraser and magic eraser. The background eraserdeletes
any part of the image that is on the edge of an object. This tool is often used
to extract objects from the background. The magic eraser tool
deletes based on similar colored pixels. It is very similar to the magic
wand tool. This tool is ideal for deleting areas with the same color
or tone that contrasts with the rest of the image.[34]
