Below in conjunction with specific embodiment the present invention implemented and is described in detail:
Embodiment one:
Fig. 1 shows the flow process that realizes of the processing method of the Application Program Interface that first embodiment of the invention provides, and describes in detail
As follows:
In step S101, obtain original interface length-width ratio and the target interface length-width ratio of application program.
In specific implementation process, due to the original interface of same application, often to pre-set one original optimal suitable
Join screen resolution, and this application program it is frequently necessary to be installed in the middle of different systems, the different boundaries of same system platform
The different interfaces of face or different system platform are likely to there are different resolution or the length and width of different interface display
Ratio, if as a example by the display interface of the different resolution of different system platform, original when pre-setting this application program one
Good adaptive screen resolution, this optimal adaptive screen resolution can adaptive a certain system platform, and when by this application program
When being installed in the system platform of another concrete different resolution, then need the processing method utilizing the embodiment of the present invention to provide first
First obtain the original optimal adaptive screen resolution of this application program, and from current system platform, obtain target device physics
The resolution of screen, such as 720P, 1080P etc., then can easily obtain this mesh according to the resolution of target device physical screen
Face length of demarcating width ratio, resolution or the title target interface resolution of this target device physical screen refer to install this system platform
Mobile terminal support screen resolution.Generally, during this application program uses, can be by calling
The application program interface function of system platform, the automatically resolution of the display interface of detection acquisition physical screen, if can not basis
Interface function obtains, generally, it is also possible to arrange this target interface resolution by hand identical with screen physical resolution.And
The step of the original interface length-width ratio obtaining application program is specially and obtains application journey according to original optimal adaptive screen resolution
The original interface length-width ratio of sequence, i.e. can obtain screen aspect according to the long dimension of this resolution with the Pixel Information of wide dimension
Ratio.
In step s 102, different from this target interface length-width ratio when the original interface length-width ratio judging this application program
Time, according to the magnitude relationship between this original interface length-width ratio and this target interface length-width ratio, obtain the original boundary of this application program
The object on face displacement parameter in visual coordinate system.
In specific implementation process, need to judge the original boundary of this target interface length-width ratio and this application program got
Face length-width ratio is the most identical, when being judged as identical, the most now need not the object on this Application Program Interface at view plane
Coordinate figure in coordinate system makes any change, directly can be by the object on this Application Program Interface in this visual coordinate system
Changing coordinates is projected as view plane coordinate, then is tied to the coordinate transform pass of target interface screen coordinate system based on view plane coordinate
System, is this target interface screen coordinate by this view plane Coordinate Conversion, or directly arranges the target interface of current system platform
Resolution is the original optimal adaptive screen resolution of this application program, so that Application Program Interface and target circle of system platform
Face adapts.
In step s 103, according to this displacement parameter, adjust this object coordinate in this visual coordinate system.
In this step S102:
The note length of original interface, width are respectively Lp, Wp, and the length of target interface, width are respectively Ls, Ws, it is judged that
If Lp/Wp Yu Ls/Ws is all higher than 1 or respectively less than 1, this displacement parameter is (Lp/Wp)/(Ls/Ws)；
The most now, this step S103 specifically includes following steps:
If (Lp/Wp) more than (Ls/Ws), then adjusting this object Y-axis coordinate y in visual coordinate system is y ', y '=y
× displacement parameter；
If (Lp/Wp) less than (Ls/Ws), then adjusting this object X-axis coordinate x in visual coordinate system is x ', x '=x
× displacement parameter.
As the present invention one example, this step S102 particularly as follows:
The note length of original interface, width are respectively Lp, Wp, and the length of target interface, width are respectively Ls, Ws, it is judged that
If Lp/Wp Yu Ls/Ws one of them more than 1, when another is less than 1, this displacement parameter is (Wp/Lp)/(Ls/Ws)；
The most now, this step S103 specifically includes following steps:
If (Wp/Lp) more than (Ls/Ws), then adjusting this object Y-axis coordinate y in visual coordinate system is y ', y '=y
× displacement parameter；
If (Wp/Lp) less than (Ls/Ws), then adjusting this object X-axis coordinate x in visual coordinate system is x ', x '=x
× displacement parameter.
In embodiments of the present invention, for convenience, below by optimal adaptive to original interface or the title of this application program
The length at the interface that screen resolution is corresponding, width represent with Lp, Wp respectively, and the mesh of this application program system to be installed
Demarcate face or physical screen length, width represents with Ls, Ws respectively, then this original interface length-width ratio is long with this target interface
Wide ratio represents with Lp/Wp with Ls/Ws respectively.
Specifically, original optimal adaptive screen resolution size 720P preset if there is an application program, should
Application program is arranged on the goal systems platform that target interface resolution is 1080P, or the current interface of an application program
Size 1080P, is installed in the situation in the goal systems platform of 720P, if this original optimal adaptive screen preset is differentiated
Interface length-width ratio and this target interface length-width ratio that rate is corresponding are 16: 9, then identical due to their length-width ratio, deserve prezone
Face length-width ratio is 1 with ratio (Lp/Wp)/(Ls/Ws) of this target interface length-width ratio, then the object on this Application Program Interface
Displacement parameter in view plane coordinate system is the ratio of this original interface length-width ratio and this target interface length-width ratio, namely this position
Shifting parameter is 1, because making any change without to this object coordinate figure in view plane coordinate system, it is only necessary to directly carry out
The imaging of this application program on view plane is converted into the coordinate step on target interface screen.
Specifically, when this original interface length-width ratio is all higher than 1 or respectively less than 1 with this target interface length-width ratio, namely
If Lp/Wp Yu Ls/Ws is all higher than 1 or respectively less than 1, it is divided into following two situation, it is assumed that object p is under visual coordinate system
Coordinate be (x, y), the coordinate after adjustment is (x ', y '):
1) if. Lp/Wp be more than Ls/Ws, then illustrate this application program be intended on the widest screen run, this
Shi Ruguo does not do any operation, then the most same fat person of effect of final display is drawn high in the width direction, now camera
Camera keeps constant from the distance of view plane, owing to Aspect Ratio changes Ls/Ws into, needs this object in visual coordinate system
Vertical coordinate y value increase.Therefore the object inside view frustums should do corresponding mobile it can be understood as actual object along Y-axis
Coordinate direction moves to y ' position, otherwise possibly cannot show, it may be assumed that displacement parameter is (Lp/Wp)/(Ls/Ws), y '=y ×
(Lp/Wp)/(Ls/Ws), and x value is constant, the respective coordinates after adjustment is (x, y ').
2) if. Lp/Wp be less than Ls/Ws, then explanation be intended to operate on the narrowest screen operation, if now
Do not do any operation, then the most same lean person of effect of final display by along length to elongation, for this solution it is required that general
The x value of this object diminishes, and therefore the object inside view frustums should do corresponding mobile, otherwise possibly cannot show, reduces X-axis and sits
Scale value, it may be assumed that x '=x × (Lp/Wp)/(Ls/Ws), and y value is constant, the coordinate in visual coordinate system of the correspondence after adjustment is
(x ', y).
Specifically, when in this original interface length-width ratio with this target interface length-width ratio, one is less than 1, and another is more than 1,
Namely if Lp/Wp Yu Ls/Ws has one more than 1, one less than 1 time, be also classified into two kinds of situations, as following:
When in this original interface length-width ratio preset with this target interface length-width ratio, one is less than 1, when another is more than 1,
Namely if Lp/Wp with Ls/Ws has one be more than, one less than 1 time, be also classified into following two situation, then firstly the need of will
Object in 3D or 2.5D Application Program Interface, all with view plane normal vector direction (camera coordinates system Z axis) as shown in Figure 2
For axle center 90-degree rotation to the left, then this each object 90-degree rotation to the right with respective centre axis Z for axle center again, after setting
Make the following judgment:
1) if. Wp/Lp be more than Ls/Ws, then illustrate that this application program is intended to operate on the widest screen fortune
OK, if the most not doing any operation, then the most same fat person of effect of final display is drawn high in the width direction.Phase at this moment
Machine keeps constant from the distance of view plane, and owing to Aspect Ratio needs to change Ls/Ws into, therefore the object inside view frustums should do phase
The movement answered, the most possibly cannot show, so only need to be increased by y-axis coordinate, be adjusted to: y '=y × (Wp/Lp)/(Ls/
Ws), x coordinate value is constant.
2) if. Wp/Lp be less than Ls/Ws, then explanation be intended to operate on the narrowest screen operation, now camera
Distance from view plane keeps constant, owing to Aspect Ratio needs to change Ls/Ws into, then needs the object inside by view frustums to do
Corresponding mobile, so only x-axis coordinate need to be diminished, it is adjusted to: x '=x × (Wp/Lp)/(Ls/Ws), y-coordinate value is constant.
And then, the coordinate after the renewal under visual coordinate of all objects on this Application Program Interface can be obtained.
