Abstract
Techniques are presented for enhanced erasing of digital ink. The ink erasing feature of a content creation application can preserve the complex shapes that can result from partial erasure of ink strokes. The ink erasing feature can receive ink stroke data from an ink stroke and display the ink stroke. The ink erasing feature can then receive and display an eraser stroke that contacts the ink stroke. Once the eraser stroke is received, the ink erasing feature can determine whether any eraser segment of the eraser stroke contacts the ink stroke. If an eraser segment does not contact the ink stroke, the ink erasing feature discards the eraser segment. If an eraser segment does contact the ink stroke, the ink erasing feature can update the ink stroke data based on amount of overlap and location of contact between the eraser stroke and the ink stroke.
