Abstract:
Techniques and systems for managing visual layouts of ink strokes are described. In particular, an ink space coordinate system for a digital ink stroke is provided. A digital ink system can receive ink stroke data of an ink stroke. The system can define an ink space coordinate system along the ink stroke. Defining the ink space coordinate system can include assigning a reference line of the ink stroke and an origin point on the reference line, as well as creating ink space coordinates. Creating the ink space coordinates can include defining ink space x-coordinate values representing a distance along the reference line relative to the origin point and defining ink space y-coordinate values representing a distance along an axis perpendicular to the reference line of the ink stroke. Then the system can perform a warping to create curvature in the ink space coordinate system.

Claim (Index 1):
A method for managing visual layouts of ink strokes, comprising:\n receiving ink stroke data of an ink stroke, wherein the ink stroke data comprises a set of ink points, and wherein two adjacent ink points of the set of ink points are connected by a corresponding ink segment; defining an ink space coordinate system along the ink stroke, wherein the ink space coordinate system forms a grid along the ink stroke, and the defining of the ink space coordinate system comprises:\n assigning a reference line of the ink stroke along the length of the ink stroke that passes through each of the ink points of the set of ink points; \n assigning an origin point for the ink stroke on the reference line; \n creating ink space coordinates, wherein the creating of the ink space coordinates comprises:\n defining ink space x-coordinate values representing a distance along the reference line relative to the origin point; and \n defining ink space y-coordinate values representing a distance along an axis perpendicular to the reference line of the ink stroke; and \n \n for any corners produced by adjacent ink segments of the ink stroke, performing a warping to create curvature in the ink space coordinate system, wherein performing the warping comprises: \n warping the ink space x-coordinate values to follow the curvature of the ink stroke by stretching the ink space x-coordinate values on a reflex angle side and compressing the ink space x-coordinate values on an opposite side to the reflex angle side, the reflex angle side and the opposite side being formed by a corner produced by adjacent ink segments; and \n warping the ink space y-coordinate values to smooth the transitions between the adjacent ink segments of the ink stroke.
