Methods of providing graphics data and displaying

摘要

A method of providing graphics data, comprising generating a first set of data vectors specifying geometrical characteristics of a graphical object in a first digital picture, generating a second set of data vectors specifying geometrical characteristics of the graphical object in a second digital picture to be displayed after the first digital picture, generating a parameter set comprising information specifying intermediate geometrical characteristics of the graphical object based on the geometrical characteristics of the graphical object in the first digital picture, and of the graphical object in the second digital picture, wherein the intermediate geometrical characteristics are geometrical characteristics of the graphical object in at least one third digital picture to be displayed after the first digital picture and before the second digital picture, and generating at least one data file comprising the first set of data vectors, the second set of data vectors and the parameter set.

1. A method of providing graphics data, comprising:
generating a first set of data vectors specifying geometrical characteristics of a graphical object in a first digital picture, the first set of data vectors representing a first key digital picture frame, generating a second set of data vectors specifying geometrical characteristics of the graphical object in a second digital picture to be displayed after the first digital picture, the second set of data vectors representing a second key digital picture frame, generating a parameter set comprising information specifying intermediate geometrical characteristics of the graphical object based on the geometrical characteristics of the graphical object in the first digital picture and based on the geometrical characteristics of the graphical object in the second digital picture, wherein the intermediate geometrical characteristics are geometrical characteristics of the graphical object in at least one third digital picture which is to be displayed after the first digital picture and before the second digital picture, generating at least one data file comprising the first set of data vectors, the second set of data vectors and the parameter set, and using predetermined definitions stored in a library file as vector information to represent the graphical object in the first key digital picture frame and the second key digital picture frame in order to reduce the size of the at least one data file; and wherein the predetermined definitions include an enhanced disk B-spline curve represented by at least one control circle, the control circle denoted by a position of a control point, a radius and a color parameter.
