METHOD AND APPARATUS FOR CREATING A GRAPHICS DATA REPRESENATATION AND SCALING A GRAPHIC REPRESENTED THEREBY

摘要

A processor is operable to generate a graphics data representation (GDR) for a graphic created at a first resolution and including two or more separated objects. The processor decomposes the objects into contours and determines features and control points along the contours. Additionally, the processor determines constraints for imposition upon the features and control points during scaling, where the constraints include spatial relationships between the control points. The processor stores the constraints, identifications of the features and control points, contour descriptions, and information identifying the first resolution to produce the GDR. Upon acquiring the GDR, a displaying device's processor determines a scaling value based on the first resolution and a second resolution at which the graphic will be displayed, adjusts features and control points of the contours based on the scaling value and the GDR constraints to produce a scaled graphic, and displays the scaled graphic at the second resolution.

1. A method for creating a graphics data representation for a graphic that includes a plurality of objects separated by one or more predefined spatial relationships, the graphics data representation facilitating scaling of the graphic from a first resolution at which the graphic was created to a second resolution at which the graphic is to be displayed, the method comprising:
decomposing the plurality of objects into a plurality of contours; determining features and control points along the plurality of contours; determining a plurality of constraints to be imposed upon the features and the control points during scaling of the graphic, the plurality of constraints including spatial relationships between control points of two or more contours constituting at least part of two or more spaced apart objects; and storing the plurality of constraints, identifications of the features and the control points, descriptions of the plurality of contours, and information identifying the first resolution as a graphics data representation in a format understandable by a processor of an electronic device.
