1. An electronic graphic system comprising:

  • storing means for storing image data;

    means for providing brush profile data;

    user manipulatable input means, providing position data and pressure data relating to pressure applied thereto by a user, for repeatedly addressing positions in the stored image determined by said position data at instances of time separated from each other by respective periods of time;

    processing means for combining user selected color image data with data in the storing means at positions in the stored image addressed by said input means, the combining by said processing means being controlled by said brush profile data;

    and wherein said user manipulatable input means includes generating means for generating, in response to said pressure data, a pulse signal comprising a sequence of strobe pulses each corresponding to a respective one of said instances of time, the period of time between each pulse being dependent upon said pressure data, said pulse signal being used to initiate the instances of time at which the user selected color image data and the image data in the storing means are combined.
