Abstract

The invention belongs to the field of computer graphics, and particularly relates to a graphic context management method. The method comprises the following steps: when the graph application is changed, the graph application attribute recording module (1) extracts the graph attribute of the current active application and sends the graph attribute to the graph attribute module (2) of the current graph; the graph attribute module (2) of the current graph receives the attribute information of the current active graph and forwards the attribute information of the current active graph to the comparator module (4); the method comprises the following steps that a graphic processor attribute recording module (3) records graphic attributes of a graphic processor, and when a graphic application is changed, the graphic processor attribute recording module (3) sends the current graphic attributes of the graphic processor to a comparator module (4); the method obtains the graphic attribute to be set by comparing the graphic configuration information of the current active application with the existing configuration information of the graphic processor, realizes the graphic context management and ensures the independence of the drawing attributes of a plurality of graphic applications.

Description

Graphic context management method

Technical Field

The invention belongs to the field of computer graphics, and particularly relates to a graphic context management method.

Background

Window systems are increasingly used as important means for human-computer interaction, and graphics context management is used as a bridge between the window systems and a graphics processor to directly determine the speed and quality of multi-window application. Most of the currently published and researched graphic processing aims at a message mechanism, a multi-thread working mode, a clip domain algorithm and the like of a graphic user interface, and relevant contents of graphic context management are not found.

Disclosure of Invention

The purpose of the invention is:

the invention mainly provides a graphic context management method which ensures the independence of drawing attributes of a plurality of graphic applications.

The solution of the invention is:

a graphics context management method, comprising:

step 1, a graph application attribute recording module (1) records the graph attribute corresponding to each graph application, and when the graph application is changed, the graph attribute of the current active application is extracted and sent to a graph attribute module (2) of the current graph;

step 2, the graph attribute module (2) of the current graph receives the graph attribute information of the current activity sent by the graph application attribute recording module (1) and forwards the graph attribute information to the comparator module (4);

step 3, the graph processor attribute recording module (3) records the graph attributes of the graph processor, keeps consistent with the current attributes of the graph processor and changes along with the change of the drawing attributes, and when the graph application is changed, the graph processor attribute recording module (3) sends the current graph attributes of the graph processor to the comparator module (4);

step 4, the comparator module (4) receives the graphic attribute information sent by the graphic attribute module (2) of the current graphic and the current graphic attribute of the graphic processor sent by the graphic processor attribute recording module (3), compares the graphic attribute information with the current graphic attribute information, extracts the operation information needing to be added, deleted and changed, and sends the operation information as graphic attribute setting information to the attribute module (5) needing to be configured;

step 5, an attribute module (5) to be configured receives the graphic attribute setting information sent by the comparator module (4), generates a corresponding graphic operation instruction and sends the graphic operation instruction to a graphic operation instruction module (7), and generates corresponding attribute recording information and sends the attribute recording information to an attribute recording information module (6);

step 6, the attribute recording information module (6) receives the attribute recording information sent by the attribute module (5) to be configured and sends the attribute recording information to the graphic processor attribute recording module (3);

and 7, receiving the graphic operation instruction sent by the attribute module (5) to be configured by the graphic operation instruction module (7), and issuing the graphic operation instruction to the graphic processor for operation.

The invention has the advantages that: according to the graphic context management method provided by the invention, the graphic configuration information of the current active application is compared with the existing configuration information of the graphic processor to obtain the graphic attribute to be set, so that the graphic context management is realized, and the independence of the drawing attributes of a plurality of graphic applications is ensured.
