Abstract
Techniques and systems for applying an ink effect to the drawing of an ink stroke can include absolute age for a digital ink stroke. A digital ink system can identify a reference time from which to represent a current time. The system can generate an absolute age of each ink point of the ink stroke based on the reference time. Then the ink effect can be applied to the ink stroke with a rhythm derived from when the ink stroke was originally drawn by using the absolute age of each ink point. In some cases, the rhythm can be the same rhythm as when the ink stroke was originally drawn. In other cases, the rhythm can be modified based on the rhythm the ink stroke was originally drawn. For example, the original rhythm may be accelerating, decelerating, skewed, compressed, affine, or non-affine.
