Application ID: 14915966

Base Claim:
1. A raster processing method of a transparent Form, characterized in comprising: determining a reusable transparent Form in a page description file; performing syntax interpretation on the transparent Form to obtain a reuse type and position information of the transparent Form; generating a color block lattice, an Alpha block lattice, a Shape block lattice and their corresponding block attribute tables and block memory tables for the transparent Form, according to the reuse type and the position information, and establishing association relationships between different transparent Forms in the page description file; computing on the generated data information to obtain and buffer assembling information of the transparent Form, according to the reuse type of the transparent Form; determining an assembling manner of the transparent Form according to the reuse type of the transparent Form and graphics status of the page to be outputted, in the assembling of the transparent Form; and assembling the transparent Form into the page to be outputted, according to the determined assembling manner and based on the assembling information and the association relationships.
