Patent ID: 6907567

Claim:
A computer-executable processing method comprising: storing a received mail document including text data and ink data, an ink image being dynamically reproduced from the ink data and overlaid on a text image reproduced from the text data when the mail document is reproduced, the ink data including coordinate information of each ink image and time information comprising a reproduction time for each ink image, a reproduction position of the ink image being defined by the coordinate information on reference coordinate axes of the received mail document, and a reproduction speed of the ink image being defined by the time information, the text data is non-ink data; inserting a character string to text data of a new document when a new document quoting the received mail document is prepared; calculating a coordinate shift amount of the dynamic reproduction position of the ink image according to a new text image reproduced from the text data to which the character string was inserted; and outputting, as the new document, the ink image which is overlaid on the new text image reproduced from the text data to which the character string was inserted, the dynamic reproduction of the ink image being executed based on the calculated coordinate shift amount, the coordinate information and the time information.
