1. A method of generating ink data in a device including a processor which is coupled to memory and to a position input sensor, the ink data including stroke objects that are vector data configured to reproduce paths formed by operating a pointer on the position input sensor, the method comprising:
receiving, in the processor, device-dependent user-input data including either one of pen event data of Type 1, which includes indicator position data and indicator pressure data, or pen event data of Type 2, which includes indicator position data but does not include indicator pressure data; determining, in the processor, whether the pen event data is Type 1 or Type 2; deriving, in the processor, one or both of radius data for defining a width of the stroke object and transparency data for defining a transparency of the stroke object, based on the indicator pressure data if the pen event data is Type 1, or based on a parameter other than the indicator pressure data if the pen event data is Type 2, wherein the parameter corresponding to indicator velocity at each of multiple points of the stroke object is derived based on the indicator position data and time information regarding when said indicator position data is received, and the radius data is determined using a function in which, when the parameter corresponding to indicator velocity increases, a value of the radius data decreases, wherein the function is selected out of multiple functions having different characteristics depending on a type of the indicator used to generate the received user-input data; and outputting, from the processor, the stroke object including said one or both of radius data and transparency data as device-independent common attribute value(s) of each of multiple points of the stroke object in a predetermined format. |
