Handling method and device for transparent form rasterization

The invention provides a handling method and device for transparent form rasterization. The method includes determining a reusable handling transparent Form in page description files, executing grammar explanation for the transparent Form to obtain reusing types and location information of the transparent Form, generating color block matrixes, Alpha block matrixes and Shape block matrixes of the transparent 'Form' and respectively corresponding block attribute tables and block memory tables, and establishing association relationships between different transparent Forms in the page description files, according to the reusing types, acquiring and caching assembling information of the transparent Forms by calculating the generated data information; when the transparent Forms are assembled, determining assembling modes of the transparent Forms according to the reusing types and graphics state of pages to be output; assembling the transparent Forms in the pages to be output according to the determined assembling modes. Rasterization handling efficiency of repeatedly citing the transparent Forms is able to be improved by the handling method and device of transparent table rasterization.
