Method and system for ink data generation, ink data rendering, ink data manipulation and ink data communication

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the apparatus to:
• receive a first fragment of a stroke object in a message associated with a first fragment identifier (ID);
• receive a third fragment of the stroke object in a message associated with a third fragment ID, the third fragment ID not being consecutive with the first fragment ID;
• interpolate a second fragment of the stroke object that is not received based on the first and third fragments of the stroke object;
• display the second fragment of the stroke object that is not received;
• after an end of the stroke object is received, transmit a request for retransmission of the stroke object, the request including a stroke ID of the stroke object.

A non-transitory processor-readable storage medium storing instructions that, when executed by the processor, cause a computer to:

• receive a first fragment of a stroke object in a message associated with a first fragment identifier (ID);
• receive a third fragment of the stroke object in a message associated with a third fragment ID, the third fragment ID not being consecutive with the first fragment ID;
• interpolate a missing second fragment of the stroke object based on the first and third fragments of the stroke object;
• display the interpolated missing second fragment;
• after the end of the stroke object is received, transmit a request for retransmission of the stroke object, the request including a stroke ID of the stroke object.
