Image processing method and apparatus

摘要

Stroke information from pen-down to pen-up being one unit is grouped automatically so that editing thereafter can be performed efficiently. Grouping of stroke information is determined in accordance with a predetermined rule of grouping each time stroke information is input or with timing indicated by a user. Strokes input within a predetermined time interval and stroke information input at a position within a predetermined distance interval are assumed to be the same group, and in the editing thereafter, a collective pointing and processing on a plurality of grouped strokes becomes possible.
