Abstract
The invention belongs to the field of computer graphics, and particularly relates to a graphics context management method. The method comprises the following steps of: when a graphics application is changed, a graphics application attribute recording module (1) extracts a graphics attribute applied by a current activity and sends the graphics attribute to the graphics attribute module (2) of the current activity; the graphics attribute module (2) of the current activity receives the graphics attribute information of the current activity and forwards the graphics attribute information to a comparator module (4); and a graphics processor attribute recording module (3) records the graphics attribute of a graphics processor, and when the application is changed, the graphics processor attribute recording module (3) sends the current graphics attribute of the graphics processor to the comparator module (4). By use of the method, graphics configuration information applied by the current activity is compared with the existing configuration information of the graphics processor to obtain the graphics attributes which need to be set, graphics context management is realized, and the independence of a plurality of graphics application drawing attributes is guaranteed.
Description
Technical field
The invention belongs to area of computer graphics, more particularly to a kind of G context management method.
Background technology
Window system is increasingly extensive as the important means application of man-machine interaction, and G context is managed as window system
Bridge between graphic process unit, directly determines the speed and quality of multiwindow application.The graphics process of disclosure research at present
In message mechanism most for graphic user interface, multithreading mode of operation, clip and paste domain algorithm etc., find no figure upper and lower
The related content of text management.
The content of the invention
The purpose of the present invention is：
Present invention generally provides a kind of G context management method, it is ensured that the independence of multiple figure application drawing attributes
Property.
The present invention solution be：
A kind of G context management method, including：
Step 1, figure application attribute logging modle (1) record each corresponding graphic attribute of figure application, when figure should
During with changing, the graphic attribute for extracting current active application is sent in the graphic attribute module (2) of current active；
What step 2, the graphic attribute module (2) of current active reception figure application attribute logging modle (1) sent works as
The graphic attribute information of front activity, is transmitted to contrast device module (4)；
Step 3, graphic process unit attribute record module (3) record the graphic attribute of graphic process unit, with graphic process unit
Current attribute be consistent, and change with the change of drawing attribute, when shape application is changed, graphic process unit category
Property logging modle (3) by the current Graphics attribute of the graphic process unit be sent to contrast device module (4)；
Step 4, contrast device module (4) receive current active graphic attribute module (2) send graphic attribute information and
The current Graphics attribute of the graphic process unit that graphic process unit attribute record module (3) sends, carries out contrast operation, and extracting needs
The operation information for being increased, deleted and being changed, the attribute module (5) that need to be configured is sent to as graphic attribute configuration information；
Step 5, the attribute module (5) that need to be configured receive the graphic attribute configuration information that contrast device module (4) sends, and generate
Corresponding graphic operation instruction is sent in graphic operation instruction module (7), is generated corresponding attribute record information and is sent to category
In property record information module (6)；
Step 6, attribute record information module (6) receive the attribute record information that the attribute module (5) that need to be configured sends, and send out
In being sent to graphic process unit attribute record module (3)；
Step 7, graphic operation instruction module (7) receive the graphic operation instruction that the attribute module (5) that need to be configured sends, under
It is dealt into graphic process unit to be operated.
It is an advantage of the invention that：A kind of G context management method that the present invention is provided, by by current active application
Graphic configuration information contrasted with the existing configuration information of graphic process unit, obtain the graphic attribute for needing to be configured,
Realize that G context is managed, it is ensured that the independence of multiple figure application drawing attributes.
Description of the drawings
Fig. 1 is method of the present invention module map.
Specific embodiment
Below in conjunction with the accompanying drawings technical scheme is described in further detail with specific embodiment.
As shown in figure 1, a kind of G context management method of the embodiment of the present invention, including：
