Embodiment Construction

[0046] Not all transparent pages can be processed by the rasterization processing method of segmented mixed assembly proposed by the present invention. Before the current page is grammatically interpreted, it is necessary to judge the page according to the relevant parameter information of the current page and the preset output parameters. Whether to meet the pre-set conditions for segmented mixed assembly of transparent page segments and non-transparent page segments. If so, divide the page into segments, and assemble each divided content lattice; otherwise, if the page is a transparent page, perform lattice processing on it according to the transparent model; if the page is non-transparent page, it is rasterized according to the replacement model.

[0047] The relevant parameter information of the current page includes: page assembly type, transparency parameter and color space type of the page.

[0048] The preset output parameters include: the device output mode and the c...

Abstract

The invention discloses a rasterization processing method of segmented mixed assembly, comprising the steps of: judging whether the page satisfies the preset transparent page segment and non-transparent page segment according to the relevant parameter information of the current page and the preset output parameters segment mixing assembly condition; and when it is judged that the current page satisfies the segment mixing assembly condition, segment processing is performed on the page; and each divided content lattice is assembled. The invention also discloses a segmented mixed assembly rasterization processing device. Adopting the segmented mixed assembly rasterization processing method of the present invention, for non-transparent page segments, page lattices can be assembled directly according to the replacement model, only for transparent page segments, page lattices need to be assembled according to the transparent model. Perform transparent color mixing operations on every pixel on the page, reducing the amount of data processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a rasterization processing method and device thereof for segmented mixed assembly. Background technique [0002] The PDF (Portable Document Format) file format is an electronic document format used to describe the content of the page. This file format has nothing to do with the operating system platform. This feature makes it ideal for electronic document distribution and digital information dissemination on the Internet. Document format, more and more e-books, product descriptions, company announcements, network materials, and emails are beginning to use the PDF file format. The PDF file format has become a de facto industrial standard in the digital information industry. In China, typesetting software also began to gradually transition from PostScript format to PDF file format. [0003] The PDF file format has undergone several versions of updates since its l...
