ABSTRACT:
There is provided a lossy ink compression system aimed at low cost, high compression of ink on hand-held platforms. The present invention detects the critical cusp, or knot points in the ink and then resamples the smooth curves between successive cusp points discarding the dynamic information. The resampled data is then scaled to more closely match the display resolution. Finally, the data is delta coded and then packed for storage.
