Inpaint reconstructs the selected image area from the pixel near the area boundary. Inpaint may be used to remove undesirable objects from still images.
Delete any unwanted object from your photo, such as extra power-line, people, text... The program will automatically inpaint the selected area to erase it.
If some unexpected object spoils an otherwise good photograph, Inpaint may be used to remove it. Simply select the object. No need for fiddly messing about with the clone tool!
