Detailed description of the invention
Purpose, technical scheme and advantage for making the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
The a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of protection of the invention.
First aspect, embodiments provides a kind of multiwindow page display processing method, at GPU (Graphics
Processing Unit, graphic process unit) place's execution following steps, as it is shown in figure 1, include：
If S101 detects the trigger action opening the multiwindow page, then carry out cutting according to preset rules to current page
Screen, it is thus achieved that the corresponding first snapshot picture of current page；The multiwindow page is for showing all pages that browser has been opened；
Specifically, user typically can open multiple page when browsing information by browser, when need to a certain
When the page opened is checked, user can click on corresponding button and trigger the operation opening the multiwindow page, wherein, here
The multiwindow page is for showing all pages that user has already turned in this operation to browser.This behaviour detected
When making, the page first checked active user carries out screenshotss according to default rule, obtains corresponding first snapshot picture.
S102, obtain position in the multiwindow page for the current page according to spheroid equation, and according to current page many
The size of the first viewing area in position and the multiwindow page in window page, determines the border of the first viewing area, and
Border periphery draws the hatching pattern of water ripples；Wherein, the first viewing area is for display the first snapshot picture；
Specifically, after screenshotss being carried out to current page through step S101, the first snapshot picture can be obtained.By
It is the page that user browses recently in current page, the therefore forefront of the first snapshot picture multiwindow page to be shown in.Cause
This is firstly the need of the position being determined the first snapshot picture being shown in multiwindow page forefront by spheroid equation, such as Fig. 2
Shown in, namely firstly the need of determining the position as 1 for first snapshot.Below in conjunction with the accompanying drawings 3, to how determining according to spheroid equation
The process on the border of the first viewing area illustrates.In the embodiment of the present invention, including on each page of current page
On the track 61 of the rolling that individual significant point (each stain as shown in Figure 3) is positioned at spheroid, and the track 61 place screen rolling
Curtain and the screen vertical of terminal 5.Specifically, the present embodiment can be by spheroid equation, the attribute being possessed according to spheroid, obtains
Current page in the multiwindow page along the position of track 61.Current page is positioned at the bottom of screen, other each history pages
Face upwards arranges in chronological order successively.After determining the position at current page place, corresponding pre-according to this position
If the size of the first viewing area, determine the border of corresponding first viewing area of current page, and in the first viewing area
Border periphery draw water ripples effect hatching pattern.
Then, as shown in Figure 2, it is thus necessary to determine that the first snapshot picture is in first viewing area 1 of fixed position
Size.If it is understood that the first viewing area 1 that the first snapshot picture of display is in the multiwindow page is excessive, such as
Take the whole viewing area below screen in Fig. 2, it is likely that other pages can be blocked, make user to select, and excessive
Display also can affect the effect that user views and admires；If the first viewing area 1 of display is too small, then user can be made cannot to see page clearly
The content in face, thus cannot distinguish which is the page needing to select.Therefore the size of the first viewing area 1 here needs
Arrange according to the size of screen.For example, the width of the first viewing area 1 can take up the 3/5-3/4 of whole screen width, and
Equal with the distance of the right and left；The height of the first viewing area 1 can be the 1/3-1/2 of whole screen height, and is positioned at screen
The bottom of curtain.
Finally, after the size of the display position and the first viewing area 1 of knowing the first snapshot picture, it is possible to really
Surely the border for the first viewing area 1.The border of determination the first viewing area 1 here can be implemented in the following manner：
Determining the position on display the first viewing area 1 border, namely transverse and longitudinal coordinate on the display screen, the periphery at borderline region is painted
Water ripples effect hatching pattern processed (wave line region as shown in Figure 2), and by the hatching pattern of water ripples effect by first
Viewing area 1 displays.
S103, open the multiwindow page, in the first viewing area in the multiwindow page, show the first snapshot picture.
Specifically, after step S102 determines the first viewing area 1, then having recorded in step S101
One snapshot picture is filled in viewing area, thus browser just can present a multiwindow page comprising the first snapshot picture
Face.The first snapshot picture in this multiwindow page can be that spheroid curve rolls with the slip up or down of user, rolls
Direction normal to screen.And as the display position of the first snapshot picture is moved to the top of screen, the first snapshot picture can be by
Decrescence little, form near big and far smaller stereo displaying effect such that it is able to provide the user a kind of many windows with 3D display effect
The mouth page, carries out selection or the switching of each browsing pages for user.
In the multiwindow page display processing method that the embodiment of the present invention provides, first determine current page according to spheroid equation
The position that the screenshotss in face show in the multiwindow page, then again determine display current page screenshotss viewing area border with
And the water ripples effect of border periphery, it is finally shown in page screenshotss on correspondence position so that this page snapshot picture can
The multiwindow page presents near big and far smaller stereoeffect such that it is able to present the multiwindow page of 3D for user, for user
Select or switching.Further, since whole processing procedure performs at GPU, GPU is special graphic process unit, therefore CPU
Just can free from the task of graphics process, go to perform other more system tasks so that full page screenshotss
Sliding process does not haves the phenomenon of card, thus does not affect the use of user.
In the specific implementation, it is to be understood that due in the multiwindow page display a certain webpage content only
The simply partial content of this webpage, if the whole screenshots of the page that user is currently browsed, then would show at the multiwindow page
When showing, will certainly the content of some screenshots be displayed without.Since cannot show, then this partial content is for browsing
It is exactly useless content for device, also can take certain memory headroom simultaneously.Therefore, in order to avoid useless image took
Many internal memories, in step S101 of said method embodiment when carrying out screenshotss operation to current page, can be according to default
Snapshot is as the image in top area in size intercepting current page and stores.Wherein, default snapshot picture here
Size can carry out adaptability setting according to actual needs.For example, it is possible to intercept the picture of 400 pixel × 400 pixels.So
The benefit done is, has only intercepted the picture that can show in the multiwindow page, thus has reduced accounting for of each page snapshot picture
It with space, is favorably improved the fluency of browser execution, provide the user more preferable experience.
It is understood that except comprising the snapshot picture of current page on the multiwindow page, also comprise history page
Snapshot picture.Therefore, many windows that on the basis of embodiment of the method described above, as shown in Figure 4, the embodiment of the present invention provides
Mouth page display processing method can also include：
S201, after the trigger action opening the multiwindow page being detected, obtain locally stored history page corresponding
Second snapshot picture；
It is understood that in order to enable the multiwindow page to show all webpages that user has opened, each user
Secondary reopening a page, browser will carry out whole screenshotss or part screenshotss to the upper page browsing, and stores
In this locality, for the display when page layout switch.Therefore, in step S101 of said method embodiment, current page is being obtained
First snapshot as while, also obtain the corresponding second snapshot picture of locally stored history page.Wherein, second here
The quantity of snapshot picture may be multiple.
S202, obtain the described history page position in the described multiwindow page according to described spheroid equation, and according to
Position in the described multiwindow page for the described history page and the size of described second viewing area, determine that described second shows
The border in region, and the hatching pattern of water ripples is drawn in described border periphery；Wherein, described second viewing area is used for showing
Described second snapshot picture；
Specifically, while determination in the position to the first snapshot picture for step S102, it is also desirable to determine other history
The position of the second snapshot picture of the page.Where like each history page can be calculated at the multiwindow page according to spheroid equation
In position.Wherein, the position of the second snapshot picture of the first snapshot picture and each history page of current page as shown in Figure 2
Putting and can sorting according to the time opened, the page opened recently is positioned at the forefront of the multiwindow page, the page opened at first
Face is positioned at the rearmost of the multiwindow page.
For each the second viewing area size setting also with in step S102 the first viewing area size phase is set
Same, do not repeat them here.
After the size of the position determining each page and corresponding viewing area, it is necessary to determine each viewing area
The border in territory.Similarly, it is first determined the position on the border of each viewing area 1-4, then overall at each viewing area 1-4
The periphery on border draws hatching pattern, displays each viewing area 1-4 finally by the hatching pattern drawn.
S203, open the multiwindow page, in the second viewing area, show the second snapshot picture.
Similarly, after determining the first viewing area and each the second viewing area, by the first snapshot picture with
And the fills of each the second snapshot picture is to corresponding viewing area, enables the multiwindow page to show multiple snapshot
Picture, each snapshot picture presents near big and far smaller state such that it is able to provide the user a kind of many windows with 3D display effect
The mouth page.And all realize on GPU due to this processing procedure, show each screenshotss after therefore opening the multiwindow page
The change of image can be very smooth, does not haves card, thus does not affect user and use, provides the user good use body
Test.
In the specific implementation, in order to when user slides the multiwindow page each page can follow the slip gesture of user
Realizing the effect that 3D rolls, the method that the embodiment of the present invention provides also includes：
S301, when the slide detecting in the multiwindow page, according to spheroid equation, in real time obtain current page
Along the dynamic position of spheroid curved slide motion in the multiwindow page；
It is understood that embodiment of the present invention rolling effect to be realized is that each page can be along spheroid curve
Roll, and the plane at track place that rolls and screen vertical.For ease of understanding, may refer to Fig. 3, the embodiment of the present invention is wanted
Being shown that each page to roll along the surface curve of spheroid 6, on each page a index point is (for example,
The central point of page coboundary) (each stain as shown in Figure 3) is positioned on the track 61 of rolling, and track 61 place rolling
Screen and the screen vertical of terminal 5.Spheroid 6 can rotate along the opposite direction of the direction of arrow or arrow, and each page is also followed
Spheroid rotates, and the direction of rotation namely the sphere at track 61 place are vertical with screen 5.And now screen 5 is equivalent to a plane,
Each page is projected in this plane with the picture that spheroid rotates, so that be positioned at the user in screen 5 front at ball
Body can see that when rotating along the direction of arrow that the page is gradually close to oneself one by one, otherwise, at spheroid along arrow negative side
Can see that when rotating one by one the page gradually to oneself away from thus forming near big and far smaller 3D display effect.
By above-mentioned narration it can be seen that here can be by spheroid equation, the attribute being possessed according to spheroid, obtain in real time
Current page in the multiwindow page along the dynamic position of spheroid curved slide motion, if namely page that current page is bottom
Face, then the attribute that can be possessed according to spheroid 6, according to spheroid equation, obtains current page and was sliding along track 61
Dynamic position in journey.Understandable, in addition to current page, the acquisition methods of the dynamic position of other history page
Identical with current page, it is hereby achieved that current page and each history page are in correspondence in track 61 sliding process
Dynamic position.
S302, the size according to dynamic position and the dynamic display area preset at dynamic position, determine current page
Face slides into the border of corresponding dynamic display area during each dynamic position, and the border periphery in dynamic display area is drawn
The hatching pattern of water ripples effect；Wherein, dynamic display area is for display the first snapshot picture；
As described above, screen 5 is a plane, and when spheroid 6 rotates in the direction of the arrow, user sees on screen 5
Be the effect that each page moves closer to.It is therefore to be understood that on the track 61 of the rolling of spheroid each position
The size of corresponding dynamic display area is different, bigger the closer to the size of on-screen display (osd) area.Therefore here can root
According to the size of the dynamic position on track 61 and the dynamic display area preset at dynamic position, determine that current page slides
Border to dynamic display area corresponding during dynamic position.Wherein it is determined that the border of the first viewing area specifically can be passed through
In the following manner is implemented：As in figure 2 it is shown, can be according to position in the multiwindow page for the current page and the default first display
The size in region calculates the first viewing area 1 border transverse and longitudinal coordinate on the display screen, namely calculates the corresponding screen in this border
On which pixel cell.Understandable, GPU now simply obtains border respective coordinates, not by by this border
It is plotted on screen.It is understood that the border acquisition mode of other history page is identical with current page, no longer superfluous at this
State.
Then can be in the periphery of current page and each history page boundary position (at twill as shown in Figure 2
Fill region) draw the hatching pattern of water ripples effect, and by the hatching pattern of water ripples effect, dashed forward in the first viewing area 1
Show to come.Understandable, detect user slide the operation of the multiwindow page when, each page is with the direction slided
Roll along track, and hatching pattern now also can change with the rolling of each page.
S303, in dynamic display area, show corresponding first snapshot picture.
Show corresponding snapshot picture in each viewing area after, it is possible to obtain comprising multiple page snapshot picture
The multiwindow page.Each snapshot picture in this multiwindow page can be as the slip up or down of user is along spheroid track
Roll.And as the display position of each snapshot picture is moved to the top of screen, the size of snapshot picture can be gradually reduced, namely
More move image toward top less, so that each snapshot picture forms near big and far smaller stereo displaying effect, carry for user
For a kind of multiwindow page with 3D display effect, carry out selection or the switching of each browsing pages for user.
In the specific implementation, should in aforementioned manners embodiment realize the multiwindow page display history web pages after, the present invention
The method that embodiment provides also includes：If the operation of the second snapshot picture chosen in the multiwindow page detected, from the page
List obtains the second snapshot as corresponding history page.
Specifically, when user opens the new page, the key message of the page before browsing and each page are corresponding
Snapshot picture be stored in page listings.Here key message can include time of page open and the page
URL address.If the operation that user have chosen a certain second snapshot picture in the multiwindow page detected, can be from pages column
Table obtains this second snapshot as corresponding history page, and show on a display screen, thus user can check this history
Information on the page.
Understandable, on the basis of said method embodiment, if a certain page detecting in page listings is closed
Closing, then deleting the corresponding key message of the page and snapshot picture, thus save the space of storage, beneficially browser is smooth and easy without card
The operation paused.
Second aspect, embodiments provides a kind of multiwindow page display processing unit, as it is shown in figure 5, include
Screenshotss unit the 401st, border determining unit 402 and image completion unit 403.
Wherein, screenshotss unit 401 is used for by GPU when the trigger action opening the multiwindow page being detected, to currently
The page carries out screenshotss according to preset rules, it is thus achieved that the corresponding first snapshot picture of current page；The multiwindow page is used for showing clear
All pages that device of looking at has been opened；Border determining unit 402 is for obtaining current page at many windows by GPU according to spheroid equation
Position in mouthful page, and according to current page in the multiwindow page the first viewing area in position and the multiwindow page
Size, determines the border of the first viewing area, and draws the hatching pattern of water ripples in border periphery；Wherein, the first viewing area
Territory is for display the first snapshot picture；Image completion unit 403 is for opening the multiwindow page by GPU, at the multiwindow page
In the first viewing area in display the first snapshot picture.
Specifically, when the operation of user's pre-switch webpage being detected, the page that active user is checked by screenshotss unit 401
Face carries out screenshotss according to default rule, obtains corresponding first snapshot picture.
After obtaining the first snapshot picture, border determining unit 402 to determine position and the border of the first snapshot picture.
Border determining unit 402 first passes through the position that spheroid equation determines the first snapshot picture being shown in multiwindow page forefront
Put.Then, as in figure 2 it is shown, border determining unit 402 further determines that the first snapshot picture in the first of fixed position
The size of viewing area 1.Being arranged on of size with regard to the first viewing area 1 has been carried out detailed being described in this not above
Repeat again.Finally, border determining unit 402 determines the position on display the first viewing area 1 border, and in the periphery of borderline region
