In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.In order to illustrate technical solutions according to the invention, illustrated below by specific embodiment.
Fig. 1 shows that the workflow of mixed display method provided in an embodiment of the present invention is only shown for ease of description
With relevant part of the embodiment of the present invention.
The mixed display method provided in an embodiment of the present invention is applied to show in electricity using Firefox OS systems
The television set of the operation system interface on visual interface upper layer, as shown in Figure 1, the mixed display method includes：
S1 is the background setting transparency of the operation system interface in webpage layout engine；
S2 goes out one or more labels from interface document analysis, and parses the pattern of the label；
S3 determines that one or more figure layer, the figure layer include one or more labels；
S4 determines the overlay order of the figure layer according to the pattern of the label, according to the figure layer overlay order according to
It is secondary to be superimposed All Layers in the background for be arranged transparency and be superimposed generation system interface figure layer, in the operation system interface
Show the system interface figure layer.
It is emphasized that in general, Firefox OS systems are for mobile terminals such as mobile phone, tablet computers.The present invention is implemented
The Firefox OS systems are used for television set by example.Firefox OS systems for display background be webpage layout engine (such as
Gecko it) provides, but since mobile terminal shows that icon or other information are required for (needing webpage layout engine using background
The background of offer), no background can not be carried out and show the information such as icon, therefore there is no modification Firefox OS systems for the prior art
This technical problem of the transparency of used background when display.It is another as stated in the background art, based on Firefox OS systems into
When the third party application exploitation of row mobile terminal, used background when the display of Firefox OS systems can not be directly changed
Transparency.
In order to meet the needs of transparence display operation system interface on a television set, the embodiment of the present invention is drawn from webpage layout
The source code for holding up (such as Gecko) modifies to the transparency of the background of operation system interface；Concrete modification operation system interface
The mode of transparency of background be：It is found from source code and the relevant parameter of transparency and changes parameter value, pass through modification
The parameter value realizes the setting of any transparency in 0 to 100% range.In turn, webpage layout engine is successfully using Firefox
The operation system interface of OS systems provides the background with certain transparency.Preferably, by changing webpage layout engine
Source code in the relevant parameter of transparency, the background setting transparency which is provided is 100%, to make
The background that transparency is 100% is provided with the operation system interface of Firefox OS systems.If existed in system interface figure layer
The pixel that pixel value is zero can pass through the transparent region (picture that the transparent region is zero by pixel value in operation system interface
Vegetarian refreshments forms) see television interfaces positioned at lower layer.
For the method for display operation system interface provided in an embodiment of the present invention, it is as follows that operation principle is described in detail：
It is superposition due to needing figure layer to be shown all when generating the system interface layer for being shown in operation system interface
In background, need to set the background that webpage layout engine provides to certain transparency in step S1 first；In turn, in life
When at system interface figure layer, based on being superimposed figure layer on the background with transparency.
It should also be noted that since the operation system interface is made of label；It needs artificially to be pre-designed out-of-bounds
Face design document (such as by artificially writing the interface file), the sample of label, label is gone out by the interface document definition
Formula, tag tree etc..
In step s3, when determining one or more figure layers, HTML parsings is carried out to interface file in advance and are solved
Tag tree is precipitated (node of the tag tree is label)；In turn, which figure layer packet determined according to preset rules (can artificially change)
Containing which of tag tree label；Alternatively, determining which figure layer includes which of tag tree label at random.
As an implementation, all under the label and the node that are included by a node when determining figure layer
The label that child node (all child nodes in the subtree being made of root using the node) includes determines in a figure layer.Preferably
It is to be limited to the label number that determining each figure layer is included within the scope of predetermined number, i.e., if institute under the node
There is the child node number that child node (all child nodes in the subtree being made of root using the node) includes more, then not by the section
The label that all child nodes (all child nodes in the subtree being made of root using the node) under point and the node include determines
In a figure layer, select the node for meeting predetermined number area requirement with determination from all child nodes in the subtree of the node
One figure layer, and then multiple figure layers are determined under the node.
In addition CSS parsings also are carried out to the interface file, CSS parses the pattern of each label in tag tree.
After being configured using the pattern that CSS is parsed to the label in figure layer, executes step S4 and carry out map overlay.It need to emphasize
It is to include according to the pattern that CSS is parsed：Size, the face of each label of the position of each label, each label
Color etc..It therefore, can be further by the pattern of label (size of position and each label with specific reference to each label)
Determine the overlay order of the figure layer comprising the label.Preferably, according in tag tree father and son's node relationships and each institute
The pattern (size of position and the label with specific reference to the label) for stating label determines the overlay order of label, and then really
Determine the overlay order of figure layer.
After good figure layer to be determined, lowest level be background on the basis of according to map overlay sequence by each figure layer successively
All Layers and background superposition are generated a figure layer (i.e. system interface figure layer) by superposition.It is provided by Firefox OS systems
Display drive and in operation system interface show the system interface figure layer.
It should also be noted that be made of label due to each figure layer of generation, it is superimposed system circle of synthesis
Face figure layer also includes label (label that each figure layer is included).There may be skies between label in system interface figure layer
Gap, the gap are the region for only not having with background any label, and the pixel number for the pixel which includes is zero；It is right
In inside tags, there is also the pixels that pixel number is zero.Due to being that each map overlay is synthesized the system in background
Interface figure layer, be that can penetrate system circle in the case where background has certain transparency (as long as transparency is not zero)
(transparent region includes for transparent region in the figure layer of face：1, the pixel that pixel number is zero in system interface figure layer, 2, system circle
Gap (pixel number for the pixel that the gap includes is zero) in the figure layer of face) see below the system interface figure layer
Television interfaces.
Preferably, when the transparency of background be 100% when, can according in the system interface figure layer whether there is pixel number
The pixel that value is zero judges whether to see television interfaces through the system interface figure layer, if it is decided that there are pixel numbers
The pixel that value is zero, can pass through the pixel composition that the pixel number is zero one or more transparent regions see and being located under
The television interfaces of layer.
Fig. 2 shows the detailed processes of step S4 in mixed display method provided in an embodiment of the present invention, for the ease of retouching
It states, illustrates only and the relevant part of the embodiment of the present invention.
In a preferred embodiment, as shown in Fig. 2, described show system circle in the operation system interface
The step for face figure layer, specifically includes：
Each pixel correspondence in the system interface figure layer is added to frame buffer zone by S41；
S42 detects the pixel for being less than default value in the frame buffer zone with the presence or absence of pixel number, if detected
Pixel number is less than the pixel of default value, and the pixel detected is deleted in the frame buffer zone, according to slow from the frame
It rushes the pixel that area is read and generates picture, in the picture that operation system interface display generates.
The present embodiment is that the display driving that Firefox OS systems provide shows the operation system interface, therefore, is needed
The system interface figure layer is rendered into frame buffer zone, i.e., by the pixel number of each pixel in the system interface figure layer
In corresponding storage to frame buffer zone.In turn, in order to further ensure that can penetrate the transparent region in operation system interface, (this is saturating
Area pellucida domain is：The one or more regions for the pixel composition that pixel number is zero in system interface figure layer) see television interfaces,
(preferably, which is driven to gralloc drive modules for the pre- display driving for first passing through the offer of Firefox OS systems；It needs
Illustrate, the gralloc drive modules be the smart television for different manufacturers and to gralloc templates (such as：
Gralloc.default.so obtained after) writing) pixel number of each pixel in frame buffer zone is detected, it detects
It is less than the pixel of default value with the presence or absence of pixel number, the pixel of default value is less than for the pixel number detected
Point deletes the relevant pixel number of pixel with detection in the frame buffer zone.
It is emphasized that the default value is close to zero；Further, the default value can be according to the saturating of background
Lightness and change size, reduce with the increase of transparency；The default value being arranged is to filter out：Frame buffer zone
In pixel number be zero pixel.When transparency is 100%, the default value may be selected to level off to zero numerical value
(0.0005), or even the default value can be set as zero.
In this way, the pixel for being zero for pixel number present in frame buffer zone, the display of Firefox OS systems is driven
It moves directly from frame buffer zone to corresponding pixel point deletion (specifically deleting the pixel data of the pixel)；This is aobvious
Show driving using is read from frame buffer zone pixel data when can read less than deleted pixel data, i.e., can not read and
The corresponding data of pixel that pixel number is zero can not add to the display driving of FirefoxOS systems when generating picture
The pixel that pixel number is zero in the figure layer of adding system interface forms a pixel loophole；In this way, correspondence system interface figure layer
The transparent region for the pixel composition that middle pixel number is zero, will present in the picture of generation as loophole.The size of the loophole,
Position and number are identical as the size of the transparent region, position and number in system interface figure layer.Therefore, it can pass through aobvious using this
Show the television interfaces for driving the picture shown in operation system interface to see positioned at lower layer.
As the embodiment of the invention, step S41 is executed by graphic package interface OpenGL, by the system
Interface figure layer is rendered into frame buffer zone, i.e., each pixel correspondence in the system interface figure layer is added to frame buffer zone.In
This executes S42 simultaneously, using gralloc drive modules, detects to be less than with the presence or absence of pixel number in the frame buffer zone and preset
The pixel of numerical value is deleted in the frame buffer zone and is detected if detecting that pixel number is less than the pixel of default value
Pixel, picture is generated according to the pixel that is read from the frame buffer zone, shows and generates in the operation system interface
Picture.Since OpenGL and gralloc drive modules belong to open source technology, and Firefox OS systems can be suitable for
System, convenient for integrating OpenGL and gralloc drive modules in Firefox OS systems.
Preferably, if the television interfaces and operation system interface that are marked off on the display screen of television set only have portion
Divide overlapping, then it is specific to whether there is the step for pixel number is less than the pixel of default value for the detection frame buffer zone
Including：For the operation system interface region Chong Die with the television interfaces, the described of the frame buffer zone storage is detected
It is less than the pixel of default value in the pixel that region includes with the presence or absence of pixel number.
Resource occupation when in order to reduce the feeling of unreality of picture, reducing the time of delete processing and reduce delete processing,
Only for the operation system interface region Chong Die with the television interfaces, it is made whether that there are pixel numbers to be less than present count
The detection of the pixel of value；Delete the pixel data corresponding with the pixel detected in frame buffer zone；It is buffered using from frame
The pixel data that area is read generates picture, and the picture is shown in operation system interface.
The picture for display region Chong Die with television interfaces, if in the picture that frame buffer zone deletes and detects
The corresponding pixel data of vegetarian refreshments, meeting is generated in the overlapping region has one or more loopholes, and user can be intuitively from through leakage
See the television interfaces of lower layer in hole.The picture for display region not be overlapped with television interfaces, can be displayed without loophole
Picture, even if in the picture there are pixel number be less than default value pixel (for transparent region).
In an embodiment of the present invention, after HTML parses the position of tag tree and label in interface file,
When step S3 divides figure layer, the step for determining one or more figure layers, is specially：It is corresponded to for each application program
Ground determines one or more figure layers.
The advantages of above-mentioned technological means is can to ensure an application program completely body in one or more figure layers
It is existing；And it is emphasized that according to one or more figure layers that an application program determines, there is the superposition being completely covered to close
System；That is, it is subtree that the application program, which is corresponded in tag tree, with the predetermined number below the root node of subtree and the root node
Child node forms a figure layer in range, and a figure layer is determined further according to multiple subtrees present in the subtree are corresponding respectively, this
Sample can determine whether out a maximum figure layer of region area, then determine the multiple small figure layers being located in the region area, they are right
Answer same application.Preferably, if application program is not complicated enough, i.e., subtree corresponding with the application program is included
Node few (being not above predetermined number range, or several nodes more than predetermined number range) is only that an application program is true
A fixed figure layer.
