PROCESSING OF ELECTRONIC INK Russian patent published in 2009 - IPC G06F15/00 G06F17/20 

FIELD: physics, computer engineering.

SUBSTANCE: invention is related to processing of electronic ink. Method of the first data structure matching with the second data structure consists in the following: for every unit of the second data structure it is defined whether this unit received change from appropriate unit in the first data structure; for every unit in the second data structure, for which it has been defined that it received change from appropriate unit in the first data structure, attempt of access is realised to this unit in the first data structure; if mentioned unit in the first data structure is unachievable, realisation of mentioned change is prevented in the second data structure; if it is achievable - it is defined, when mentioned change in relation to the second data structure creates optional collision, and sometimes obligatory collision; if change creates optional collision, it is defined whether it is prohibited by collision criteria; if optional collision is not prohibited, mentioned change is performed; if it is prohibited - realisation of mentioned change is prevented, at that mentioned collision criteria prohibit removal of ink strokes from end unit under fixed unit.

EFFECT: expansion of method functional resources.
