Provided is a method for erasing electronic handwriting on a clipboard. The method comprises: step 1: the coordinates of each handwriting point of the electronic handwriting are made to correspond one-to-one to the writing pressure on the clipboard and are stored, and the color depth of each handwriting point on the clipboard is made to be proportional to the writing pressure at the handwriting point; step 2: the coordinates of each erase point, on the clipboard, contacted by the eraser used for erasing electronic handwriting are made to correspond one-to-one to the erasing pressure applied to the clipboard by the eraser via the erase points; step 3: one by one, it is determined whether the coordinates of the erase points are the same as one of the coordinates in the handwriting points, and if so, then the color depth at that erase point is determined according to a first non-negative rule; otherwise, the color depth at the erase point is the background color depth of the clipboard. The method improves ergonomics and ease of use when erasing electronic handwriting. |
