Abstract:
1. In a computing system that has access to sets of related graphical objects, each set of related graphical objects including outlines representing individual graphical objects from the related set of graphical objects, a method for dynamically altering the outline of a graphical object, the method comprising accessing an outline representing a graphical object, the graphical object comprising a stroke pair comprising a first stroke and a second stroke which are similarly oriented; calculating the width of the first stroke; calculating the width of the second stroke; calculating the distance between the first stroke and the second stroke by determining the distance between an edge of the first stroke and a corresponding edge of the second stroke; determining a location of a center line between the first stroke and the center stroke; constraining the calculated distance between the first stroke and the second stroke to mitigate the possibility of rounding errors causing the represented stroke pair to be inappropriately rendered; based upon the constrained calculated distance between the first stroke and the second stroke, individually constraining the first stroke to be a specified distance from the determined location of center line between the first stroke and the second stroke and individually constraining the second stroke to be a specified distance from the determined location of center line between the first stroke and the second stroke; adjusting the represented stroke pair in accordance with the constrained calculated distance between the first stroke and the second stroke and the individually constrained distances from the first and second strokes to the location of the center line between the first stroke and the second stroke, including: constraining the adjusted stroke pair between external reference points such that the graphical object is configured for appropriate rendering relative to at least one other graphical object; and rendering the graphical object, including the adjusted constrained stroke pair, at an output device.
