Abstract
A method of generating a calligraphic ink object, comprising sampling contact coordinates generated by a coordinate input device during writing thereon using a pointer to generate an ink trajectory generally representing the writing; generating an ink envelope, the ink envelope comprising line segments joining pointer instances at the sampled contact coordinates; generating a smoothed ink envelope at least by fitting curves to points on the ink envelope; and drawing the smoothed ink envelope on a display thereby to generate the calligraphic ink object.
