| 摘要 |
The present invention discloses a method, apparatus, and article of manufacture for compressing vector data. The vector data is normalized to create normalized vector data. A history buffer is searched for a longest matching vector data that matches the normalized vector data. The longest matching vector data is encoded by assigning a substitution code. The vector data is normalized by translating the vector data to an origin and scaling the vector data to a unit square. The substitution code includes a denormalization function, which converts the normalized vector data to vector data.
