Growing along with the multimedia industry, UI design and coding can not satisfy the demand of modern software design, more for the process that embodies modern UI and coding combination.
From appearance that time of graphic interface, user interface (UI) has just entered a special period of history.In coming years, the look ﹠ feel of historic significance has appearred much having.On the other hand, computer nowadays process chip develop rapidly, particularly display chip, display card almost becomes a miniature computer.But its powerful disposal ability is not but used fully.At present, the disposal ability of display card GPU (Graphics Processing Unit) only is applied in recreation and multimedia field mostly.In order to provide the strongest experience to the user, system adopts brand-new graphics subsystem.
The graphics system of windows platform mainly contains: GDI, GDI+, Direct3D.Wherein, the application of GDI is the most extensive.The GDI graphics system formed a lot of years and had formed gradually the cover exploitation system of oneself.It provides 2D graphics process, text-processing, and limited image processing function.Though support the GDI of part to quicken on some display cards, its effect is compared still very small and weak with present Direct3D.It is in 2000 that GDI+ begins to occur, and the Alpha that it has introduced anti-aliasing, floating number coordinate, gradual change and the single pixel of 2D figure supports.It almost supports all picture formats commonly used.But GDI+ is without any quickening function (all being to realize with software).
Interactive UI workflow has comprised following core technology:
The design of workflow and processing: the flow process trend that comprises the UI workflow;
The automatic generic frame of code: integrate and improve the function of WPF, according to the standard control storehouse of WPF, the automatic generic frame of code allows UI designer's design can be converted to the front end code; The self-defined framework of UI, the framework that presents of UI is overlapped in design one, since make software at the End-Customer end, also can allow the client carry out the self-defined setting of UI easily according to demand.
UI workflow advantage:
Mode by workflow is transmitted respective document automatically, realizes the integrated of UI design, audit and loading;
By integrated mode that UI design and UI generation is integrated, save the programmer and carried out the work that UI loads;
Integrated multiple back work, the operation that made things convenient for each process.For example inherited the pixel map processing in the UI design, instruments such as polar plot processing can directly carry out the processing of graph image; Inherited the pen annotation module when audit, the annotations and comments of can directly realizing punctuating have made things convenient for expression, need not look like traditional WORD mode.
The UI workflow lasts till client always, can give the authority of client portion operation UI, allows the client can oneself define UI according to demand in terminal.
Interactive information managing I FMDP-IMIS
System realizes the visualized management of user, equipment, data, operation flow, system maintenance by template, the modularization information management of the self-defined configuration of windowization., click action dilatory by simple touch-control can realize the management of above-mentioned data, as: increase and decrease user, configuration device, check device parameter, upgrade distributing data, adjust the increase and decrease of release news pattern, systemic-function etc.Help the visualized management of user, break away from the backstage configuration of menu mode, coding type in the past, reduce system's operation risk of user, reduce maintenance cost system information.
Safety management IFMDP-ISAF
System adopts crystal ball independent research, exclusive IFMDP agreement, when guaranteeing the undistorted narrow band transmission of digital information, guarantees that the data of transmission are not lost, do not revealed.To terminal divide into groups, the active remote management mode of classification, network control, carry out unified, multistage management at server, the storage safety and the transmission security of system have been guaranteed, for the user provides safe, stable interactive full medium digital information system.
Distributed architecture
Mainly be say the information source and the stay of two nights for position and distribution, I take charge of product and mainly come configuration mode according to customer demand, mainly the form by the interface finds relative method to carry out, for the customer demand pattern is come matching process:
Multiplexed same footwork:
This method becomes a data flow with a plurality of related media streams are multiplexing, and by a guaranteed Channel Transmission, receiving terminal only needs demultiplexing and need not again synchronous.This method is very simple, need not clock synchronization, does not also need extra channel to come the transmitting synchronous data of description.
The synchronizing channel method
This method transmits each Media Stream without change in channel separately, and has utilized additional channel to come the transmitting synchronous data of description.This method mainly is applicable to the situation of having only an information source in the system.
Pass synchronous data of description method earlier
This method was sent to receiving terminal with the needed total data of whole playing process with the form of file before transmitting multi-medium data.
The sync mark method
This method says that transmitting terminal sync mark insertion Media Stream needs synchronous place, and each Media Stream transmits in channel separately, and these Media Streams of rx-side buffering know that all Media Streams that have same tag reach, and realize Synchronization Control thus.This method is comparatively simple, and processing expenditure is little.
The time tag method
This method is placed on a relative time with each Media Stream and draws up, the determining positions that media units draws up at relative time his relative time label (Relative Time Stamp RTS), has
The media units of identical RTS is play simultaneously, reaches synchronous thus.
UIWorkflow partly forms by following three: visual UI control; Visual UI makes up the storehouse; Interactively UI workflow.The UI control combines with the structure storehouse, has promoted user's efficient, has reduced maintenance cost, realizes based on user-defined service management and interactively UI workflow is quick, makes deployment simply, conveniently, and the experience effect of What You See Is What You Get is provided for the user.
Growing along with the multimedia industry, UI design and coding can not satisfy the demand of modern software design, more for the process that embodies modern UI and coding combination.
From appearance that time of graphic interface, user interface (UI) has just entered a special period of history.In coming years, the look ﹠ feel of historic significance has appearred much having.On the other hand, computer nowadays process chip develop rapidly, particularly display chip, display card almost becomes a miniature computer.But its powerful disposal ability is not but used fully.At present, the disposal ability of display card GPU (Graphics Processing Unit) only is applied in recreation and multimedia field mostly.In order to provide the strongest experience to the user, system adopts brand-new graphics subsystem.
The graphics system of windows platform mainly contains: GDI, GDI+, Direct3D.Wherein, the application of GDI is the most extensive.The GDI graphics system formed a lot of years and had formed gradually the cover exploitation system of oneself.It provides 2D graphics process, text-processing, and limited image processing function.Though support the GDI of part to quicken on some display cards, its effect is compared still very small and weak with present Direct3D.It is in 2000 that GDI+ begins to occur, and the Alpha that it has introduced anti-aliasing, floating number coordinate, gradual change and the single pixel of 2D figure supports.It almost supports all picture formats commonly used.But GDI+ is without any quickening function (all being to realize with software).
This subsystem has adopted the pluses and minuses based on GDI and GDI, especially base and WPF know-why realized to UI design, coding, the integrated centralized management that carries out.System operates among the windows especially and has deposited GDI, GDI and Direct3D.But all operations of system all do not rely on GDI and GDI+, but depend on powerful Direct3D API indirectly.Be native system core component figure below.
Among the last figure to be denoted as bolarious be three big core components of system, milcore assembly wherein, its responsibility is to finish mutual with Direct3D.And for efficient and security consideration, milcore is realized by unmanaged code.In all demonstrations finish by the DirectX engine, can realize that efficient hardware and software present.System also requires internal memory and execution are accurately controlled.Combine engine among the milcore is subjected to the performance impact relation big, and the many advantages that need abandon CLR improve performance.
The two big core component PresentationeWork and the PresentationCore of native system are positioned on the all-purpose language Runtime Library (CLR).So just as can be seen, most of code of system all exists with the trustship form.This two big assembly provides and has called function library and the function storehouse that the WCF project needs, owing to be that form with trustship exists, so the possibility of also having avoided our direct control bottom and having occurred revealing such as internal memory.
WPF basic function structure:
System has been divided into five bulks (Presentation Core P, User Interface Services, Base Services, Document Servies and XPS Viewer) as can be seen altogether:
Presentation Core: comprised all graphical effects, as figure, 2D figure, 3D figure, text, audio frequency, video and display effect.Also comprise powerful animation effect simultaneously, animation can be used all elements of front.Nethermost that is exactly the vision basic element.
User Interface Services: comprised Application Services (application program service), Deployment Services (deployment services), Controls (widget library), Layout (layout) and Data Binding (data binding).
Base Services: XAML support, Accessibility (raising development efficiency), Input﹠amp are provided; Events (support of input and incident), Property, System (property system).
Document Servies and XPS Viewer then provide basic printing and statistical tables and reports service, can realize self-defining printing and display effect by these assemblies.
The whole network transmission technology
Many-sided situation has been considered in the whole network transmission, and Network Transmission is optimized, and comprises following core technology:
TCP speed technology:, improve the transmission speed of TCP by more accurate packet loss judgement and prediction algorithm etc.
Network flow monitoring and self adaptation: by the monitoring and the self adaptation adjustment of network traffics, can be implemented in network condition good call the UDP network, when network condition is bad, call the TCP network.
