It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, and It is not used in restriction the application.

Fig. 1 is the applied environment figure of image antialiasing processing method in one embodiment.Referring to Fig.1, the image antialiasing Processing method is applied to image antialiasing processing system.The image antialiasing processing system includes terminal 110 and server 120. Terminal 110 and server 120 pass through network connection.Terminal 110 specifically can be terminal console or mobile terminal, mobile terminal tool Body can be at least one of mobile phone, tablet computer, laptop etc..Server 120 can with independent server or It is the server cluster of multiple server compositions to realize.

Wherein, terminal 110 includes operating system, simulator and corresponding application program etc..Simulator runs on terminal In operating system.Application program is run in simulator, and simulator can simulate corresponding third party's operating system, for using journey Sequence provides running environment.Simulator includes system component and image rendering agency.Application program includes image rendering module and control Molding block.It should be noted that application program need to be run in third party's operating system.

The developer of application program researches and develops and maintenance applications, and passes through the distribution channel of application market (as application is precious) Push simulator to user (such as Tencent's hand swims assistant).User downloads simulator in application market, and in the operation system of terminal It is installed on system.Simulator simulates third party's operating system, to provide running environment for application program.

Application program includes at least control module and graph rendering module.Image rendering module is used for system component (such as Android system component) render instruction is issued, to carry out subsequent processing to render instruction.Control module is used for according to input Operation application program is controlled accordingly.

Simulator includes system component and image rendering Agent components.Wherein, system component is receiving application program When render instruction, render instruction is encoded.In addition, system component the corresponding parameter list of render instruction can also be encoded into Row coding.Data after coding are transmitted to the image rendering Agent components of simulator by system component.

When image rendering Agent components receive render instruction, render instruction is first decoded, then analyzes render instruction and right The parameter list answered judges the image sawtooth degree of image in application program.Image rendering Agent components combine different types of Antialiasing mode modifies render instruction.On the one hand the render instruction of modification carries out antialiasing processing to image, on the other hand can be certainly Protect to reaction type the fluency of application program.

Modified render instruction is transmitted to video driver and executed by image rendering Agent components, by video driver according to wash with watercolours It has a finger in every pie order and rendering and antialiasing processing is carried out to image.The image by antialiasing processing is obtained, and image is in by treated Now give user.

As shown in Fig. 2, in one embodiment, providing a kind of image antialiasing processing method.The present embodiment mainly with This method is applied to the terminal 110 in above-mentioned Fig. 1 to illustrate.Referring to Fig. 2, which is specifically included Following steps：

S202 receives the render instruction that application program is triggered.

Wherein, image antialiasing processing method can be applied to simulator, and application program runs on simulator, simulator operation In operating system, video driver runs on operating system.Specifically, simulator can be mounted to it is in terminal, for simulating The application software of third party's operating system, the Android simulator including simulating Android operation system, as Tencent's hand swims assistant.Simulation Device simulates third party's operating system, can be the application providing system running environment.Operating system, which refers to, operates in end Native operating system on end.Video driver can refer to the program of driving video card, be carried out by driving video card corresponding Rendering operations and antialiasing operation etc..If operation can be by terminal performed by terminal in subsequent embodiment without specified otherwise Simulator executes.

It should be noted that if the running environment of application program is third party's operating system, then terminal original cannot be run on The operating system of beginning.For example, it is assumed that the native operating system of terminal is Windows operating system, application program A is applied to Android Operating system, then, application program A is unable to run in the terminal of Windows operating system, to run application at the terminal Program A then need to install Android simulator in terminal and simulate Android system, by simulate come Android system provide using journey The running environment of sequence A.

In one embodiment, when a triggered event is detected, terminal receives the render instruction that application program is triggered.Touching Hair event can be：Start application program in simulator, or runs application program in simulator.Specifically, when using journey When sequence starts or runs in simulator, application program generates the render instruction of rendering picture, and application program is sent to mould Quasi- device.Simulator receives the render instruction that application program generates.

In one embodiment, terminal receives the rendering that application program is triggered by the system component in simulator and refers to It enables, and after encoding to received render instruction, the render instruction after coding is passed to the image rendering generation in simulator Manage component.Terminal obtains render instruction by the image rendering Agent components in simulator, solves to the render instruction of acquisition Code.It should be noted that due in operational process system component and image rendering Agent components there is different threads, to rendering Instruction transmits render instruction after being encoded among the different threads.

S204 determines the corresponding image sawtooth degree of render instruction.

Wherein, image sawtooth refers to that rough corner angle occurs in the contour edge of the image after rendering.The shape of image sawtooth The resolution ratio for being mainly image at reason is low, will when the low image of resolution ratio is shown in high-resolution or large-sized terminal The problem of will appear image sawtooth.Visually, image sawtooth degree can refer to rendering after image contour edge corner angle it is big Small, when the corner angle of the picture contour edge of image are larger, expression image sawtooth degree is larger.When the picture contour edge of image Corner angle are smaller, indicate that image sawtooth degree is smaller.

In one embodiment, terminal determines rendering by the picture size of image to be rendered and the displaying size of terminal Instruct image sawtooth degree corresponding, for image to be rendered.

In one embodiment, it when picture size, which is less than, shows size, indicates the image exhibition to be rendered of low resolution It is shown in high-resolution terminal, in fact it could happen that largely sawtooth.When picture size, which is equal to, shows size, indicate to differentiate Rate and the consistent image to be rendered of the resolution ratio of terminal display screen are showed in terminal, in fact it could happen that lesser degree of sawtooth.Work as figure As when size, which is greater than, shows size, indicating that the image to be rendered by the resolution ratio that resolution ratio is greater than terminal display screen is showed in end End sawtooth may not occurs or the sawtooth of small degree occurs.It is referred to it should be noted that image to be rendered is showed in terminal Image to be rendered is showed in terminal after rendering and antialiasing is handled.

For example, being shown when picture size is less than and shows size since the lower image of resolution ratio is amplified to high-resolution When display screen, serious rough corner angle will occur in image amplification sampling back edge profile, that is, serious image sawtooth occur.When When picture size is equal to displaying size, then there may be the image sawtooth of O-level.When picture size, which is greater than, shows size, Illustrate that application program may use antialiasing mode and carry out image antialiasing operation, to keep image sawtooth degree smaller, adopts Antialiasing mode can be SSAA (Super Sampling Anti-Aliasing, super sampling anti-aliasing) mode.

For the application program for operating in simulator, application program itself is possible to be provided with corresponding antialiasing side Formula, it is also possible to not set corresponding antialiasing mode.When application program is provided with corresponding antialiasing mode, application is indicated The render instruction of program triggering uses antialiasing mode.When the not set corresponding antialiasing mode of application program, indicate to answer Antialiasing mode is not used with the render instruction that program triggers, then executes S206.
