Embodiment

Please specifically referring to currently preferred embodiment of the present invention, its example provides in the accompanying drawings now.The preferred embodiment is a station server PC, is made of 128MB RAM at least, super wide fast-SCSI Magnetic Disk Controller, the network interface controller of 4GB hard drive space, and LAN/WAN/Internet at least Intel Pentium Pro200MHz processor.This server operation Windows nt server edition 4 operating system comprises NT file system, Microsoft Internet Information Server version 3, and network representation server software.This server and client computer are by the configuration of TCP/IP procotol, to support HTTP (Web) agreement.Except Web browser, do not need other software on the client computer.Preferred Web browser is Internet Explorer 3.0 or Netscape 3.0 and highest version more thereof.

At first referring to Fig. 1, comprising that client workstation 10 and 20 network are connected by network is connected to network representation view server 100, the latter comprises a network server interface, preferably adopt the web server 30 of HTTP (HTTP), request intermediary 40, foreground view composer 50, view tiling display buffer 60, background view composer 80, garbage collector 70, and the document storage equipment 90 that comprises image file.

Network representation view server, promptly client workstation or " workstation " 100 can be realized on computers, for example dispose the computer realization of processor, I/O, storer, magnetic disk memory and network interface.This network representation view server 100 disposes webserver operating system and web server software 30, provides the link of network http protocol to client workstation 10 and 20.Typical network comprises by one, some the time by a plurality of, the webserver provides many workstations of service, this server serves as the storehouse of the file that can visit at the maintenance work station.

In operation according to the inventive method embodiment, utilized the Web browser on the client workstation, the ratio of the image view 110 (Fig. 2) of user's request and zone are by adopting the HTTP formative especially uniform resource locator of language (URL) sign indicating number to specify, Web server can be decoded into the URL sign indicating number certain request, and send the image view arrangement software to, this URL sign indicating number has been specified the image file that need browse, the zone of the ratio of view and the image that need browse.The network representation server sends the client computer of html data to the hyperlink with precomputation, sends specific request to server by clicking image region, with zones of different of paying this figure or the resolution that changes image.The formed HTML of this request also comprises the hyperlink of the precomputation of other selection that the user may use.

This sign indicating number sends to the webserver by network, web server software on the webserver is explained request 120, send browse request URL to foreground view composer software by common gateway interface (CGI), this CGI can handle the HTTP request of web server software outside, thereby instruction request intermediary 130 obtains specific request view, the appointment of the ratio of this view and region conforms URL.

Foreground view composer initialization 140, after the view 150 that from the webserver stores device, regains request, the view of layout request.Foreground view composer software is explained view request, this view is calculated in which view tiling needs show, generate the required view tiling of this view and show 160, generate the HTML(Hypertext Markup Language) output file then, to the layout of Web browser explanation view, unless the necessary view tiling of satisfied request shows as calculated and is stored in the buffer memory of workstation that at this moment, the WEB browser recovers good as calculated tiling demonstration.In the above two kinds of cases, foreground view composer format output 170, the view of initialization background then composer 180, the latter is sent to the WEB server with formative output, the WEB server then will format output and be sent to the WEB browser 200 of asking on the workstation1 0 by network, request browser display any view tiling of buffer memory shows 210, and shows 220 from the view that has just the calculated tiling that server is fetched.

The generation of view tiling demonstration 160 is handled by image tiling demonstration routine, the latter will become less visual lattice (Fig. 3 A) as the given page division of image processing, be called the view tiling and show A1, A2, B1 etc. (perhaps just tiling demonstration in the view image server-wide).Calculating these tilings at the different resolution (Fig. 3 B) that according to the URL requested service device that receives from the workstation browser software is given image shows.The use that tiling shows makes on the image view server, and buffer memory 60 efficient of the pictorial data of browser 10 improve on the client workstation.

Preferred view tiling display format is 128 pixels * 128 pixel gif image files.For the consideration of the compatibility and the image file size of WEB browser, the gif image file is preferred.The gif image file layout is the figure WEB browser of the most extensively supporting, thereby makes that the client computer of image view server is compatible maximum.The gif image form has desirable low Data Compression of Image loss characteristic, rational data compression ratio, and color and gray scale support, and less relatively image file head, the latter shows that with the view tiling selection of size is relevant.Tiling shows if the original image data size is 2048 byte black and white views, 4 to 1 typical GIF compression, and then the packed data of view tiling demonstration is about 512 bytes.To many view file forms, for example TIFF and JPEG, if image is less, for example the view tiling shows, then the size of image file head (and other Overhead, for example data directory) can with pictorial data itself quite; And the GIF head of soot-and-whitewash has only increased by 31 bytes seldom in the gif image file.Also can adopt another kind of view tiling display format, portable network graphic (PNG) for example is especially because extensive gradually to the local browser support of this form.

The tiling of 128 pixel view shows that size is that the view tiling shows that granularity and view tiling show the good compromise of expense.The view tiling of 128 pixels shows that granularity has determined the minimum view offset distance (plan range) that test pattern WEB browser and rank 2HTML format can realize.When browsing per inch 200 pixels image with 1 to 1 ratio, it can adjust the view position on 0.64 inch lattice.The view tiling shows that big or small reducing makes that view location lattice are more careful, shows that expense becomes greatly but problem is the view tiling.

View tiling demonstration generally presents about 128 * 128 byte image files.If the view that shows is reduced to 2 to 1, each view tiling shows 256 * 256 pixel regions of having represented the image file that is reduced to 128 * 128 pixels in proportion so.For each possible scale factor, all there is one group of tiling to show this view.The benefit that the tiling of fixed size view shows is that server and client computer can more effectively be used caching mechanism.For example, consider that 512 pixels take advantage of the view of 512 pixels.Tiling shows that this view is made up of the single gif file of WEB browser display, if these view offset 256 pixels of customer requirements then need to generate new 512 * 512 gif image, and send the WEB browser to.Show that by tiling first view will require to calculate 16 view tilings and show, and send the WEB browser display to.When sending the view request of skew 256 pixels, only need to calculate 256 and take advantage of 8 view tilings of 512 pixel regions to show.In addition, only need to transmit 8 new view tilings and be shown to the WEB browser, show because the skew view will be reused 8 available in WEB browser rs cache view tilings.The use that tiling shows makes calculates in this example and data transmission reduces by half.

The use that view tiling shows makes efficiently next view request of the precomputation view tiling demonstration that may need of image view server.The view tiling that image view server background view composer calculates around the nearest view request shows, in order to the proposition of skew view request.If request skew view, then the foreground view composer can use the view tiling of precomputation to show, thereby does not need to calculate the time that new view tiling shows for this view.For the image of frequent access, the tiling of the view of view shows that being present in the View tile display buffer lied is a good opportunity, shows because the view tiling shows the view tiling of having safeguarded nearest visit.Because may generate millions of view tilings shows, the final memory capacity that surpasses the image view server, so when arriving maximum storage distribution or the restriction of minimum memory free space, the minimum view of View tile display buffer lied garbage collector elimination visit in the recent period tiles and shows.

Handle quantity that the required tiling of the view of given view size shows and view tiling and show that big or small square is inversely proportional to.64 pixel view tilings shows that quantity that needed view tiling shows is to handle required 4 times in identical view zone, thereby its preferred property is poor slightly.The view tiling shows that expense is present in the quantity of data volume and network transactions processing.The data volume expense is from image file head size, as the part of above-mentioned total image file size, and needs to carry out in the html text file view tiling and shows and quote required data.The network transactions processing expenditure tiles and shows and increase all need network transactions to handle because each view tiling shows along with neglecting figure.Less view tiling shows that size requirements network transactions processing quantity increases, thereby has slowed down view processing response speed.

The HTML output file that the foreground view composer is generated is transmitted to web server software, sends the WEB browser to.Figure WEB browser utilizes the HTML output of image view server, serves as image browser, and layout also shows the image tiling array of display that forms image view.The html page data have been listed size, position and hyperlink for each the view tiling that needs to show shows.The view tiling shows that this form can be by all common figure WEB browser display with the gif image stored in file format.Each the view tiling that shows if desired shows and is present in the local cache that the WEB browser is retrieved the view tiling and shown from local cache, otherwise from the image view server retrieves.

Request intermediary 40 receives raw requests from network server interface 30, explains request, communicates by letter with other system unit, determines to provide which type of suitable response.It determines also when response is returned.In a preferred embodiment, request intermediary is realized by WEB server common gateway interface (CGI).Also can adopt other application programming interfaces (API) towards the WEB server.

In order to support the tiling demonstration and the buffer memory of many images on the same image view server, the sign that each view tiling shows must be unique, can show that by the view tiling URL quotes by the WEB browser.This uniqueness shows that by memory location and view tiling the combination of name realizes.Uniqueness between the image all has an independent storage sub-directory to realize in View tile display buffer lied by each image.The view tiling of the view of every kind of ratio shows that uniqueness realizes by each view tiling display file name.This view tiling display name preferably adopts following form:

V<SCALE><TILE_NUMBER>.GIF

＜SCALE〉value is 2 character strings that basic 36 codings according to the scale of view number of representing in per 256 parts generate.＜TILE_NUMBER〉value is to show 5 character strings that basic 36 codings of number generate by the tiling that following formula is determined:

TILE_NUMBER＝TILE_ROW*IMAGE_TILE_WIDTH+TILE_COLUMN

In the aforementioned calculation, TILE_ROW and TILE_COLUMN value are since 0.For example second tiling of first of 2: 1 view of the ratio row is presented in the preferred protocol and will be named as: V3J00001.GIF

The URL completely that second tiling of first of the image of numbering 22 row shows on the image view server quotes and is:

http：//hostname/view-tile-cache-path/000022/V3J00001.GIF

Except view tiling display position and scale of view, other view properties also can be encoded into the part of view tiling display-memory position or view tiling display name.These attributes are the view anglec of rotation, view x mirror image, view y mirror image, counter-rotating view.View tiling display name with these additional views attributes can be encoded into:

V<SCALE><TILE_NUMBER><VIEW_ANGER><X_MIRROR><Y_MIRROR><INVERT>.GIF

The form of VIEW_ANGLE is A＜ANGLE〉.X_MIRROR, Y_MIRROR and INVERT are respectively by single character X, Y and I coding.An example is:

V3J00001A90XYI.GIF

WEB server 30 is configured to discern the request uniform resource locator (URL) of the above-mentioned specific formatization that need be handled by image view server requests intermediary 40.This realizes with URL path or the related of document files extension name by request intermediary 40.

Foreground view composer 50 is explained view request order 140, and decision needs which type of view of layout.This view request can be absolute, has specified ratio and position, also can be relative, specified with respect to the ratio of last view and the variation of position, or implicit, select view according to the system default value.

In the view software for calculation routine 150 shown in Figure 7, command interpreter 151 receives view request, determine that 152 these views need the view tiling of what ratio to show lattice, and need which type of view tiling to show (Fig. 2) in the lattice of this view 150, generate the view tiling and show 153, produce formative view output 154.

View tiling display generator routine 160 is finished the actual generation that the view tiling shows according to preferred steps shown in Figure 8.The information which type of view tiling this view that view tiling display generator reception view calculates needs show.Which tiling record in its access cache 80 is determined to have generated and is shown and reside in the buffer memory.If the tiling of required view is presented in the buffer memory, upgrade its last visit time so, delete this view tiling and show to prevent the buffer memory garbage collector.If required view is not in buffer memory, view tiling display generator generates view tiling demonstration according to image file 90 so.View tiling display generator adopts supports many digital document file layouts, comprise black and white scanning image, gray scale scanning image, chromoscan image and many abundant in content non-scan formats, for example the software image library of Adobe PortableDocument Format (PDF), PostScript, HPGL etc.When handling the soot-and-whitewash data, utilize the adjustment of image library ratio gray scale can provide visual and better reproduce for the image that generates.

For example, the particular figure request can comprise file B2, C2, B3 and C3 (Fig. 4 A and Fig. 5 A).If after browsing these tiling demonstrations, what the client computer decision needed is exactly remaining view, and server sends to tile and shows A2 and A3 (Fig. 4 B and Fig. 5 B) so.This supposition client computer keeps other tiling and shows in buffer memory.If client computer does not have buffer memory, send tiling so and show A2, A3, B2 and B3.

The format output that generates is pointed to the view tiling that needs to show full view and is shown.Formative output adopts HTML to describe needs order, position and the hyperlink of each of demonstration view tiling demonstration.The output format device also adopts other to optimize and detects empty view tiling demonstration, the specific blank hyperlink that tiles demonstration of image is replaced to public blank tiling demonstration quote.This makes transmission that blank tiling shows for once, in case and the WEB browser rs cache public blank tiling show, no longer need to transmit any blank tiling and show.

Foreground view composer 50 control background view composers 80, when the prospect view stops the background view during just in layout, then in layout after the new view 180, start the background view with up-to-date view information.

Background view composer 80 preferably is programmed for can be by precomputation, i.e. layout is mail to the view tiling that needs between the view request of server and shown to come the optimization system performance.Need the tiling of precomputation to show it is that the tiling on every side of nearest view shows, identical with the ratio of nearest view.The view tiling shows that the order of precomputation is the clockwise spiral order of nearest view.The quantity that the tiling of the view of precomputation shows around the view may show from unwanted view tiling to prevent to generate utterly uselessly preferably by the system configuration parameter restriction.In case arrived the maximum quantity that the precomputation view tiling of nearest scale of view shows, can continue another scale of view of precomputation.Background view composer preferably is programmed for and can reduces the interference to even more important system task with low priority work as far as possible.

Fig. 6 A shows the working method of background view composer.The given view of supposing client requests need be paid tiling and show C3, C4, D3 and D4, after these tiling demonstrations are consigned to the WEB browser, background view composer routine in the server program is from E4, by layout or calculate these tilings tilings around showing and show, generate these around tiling show.As long as client computer continues to browse this page or leaf with this scale factor, the view tiling that server will calculate the tiling demonstration of request last time shows export-oriented expansion.Fig. 6 B shows client computer after two kinds of rotations that generate the tiling demonstration, another request of being sent.This request requires tiling to show G3, G4, H3 and H4.When the precomputation of this request began, the tiling that it can generate in first rotation showed G5, H5, I5, I4, I3, I2, H2 and G2, but the tiling that it can not attempt generating in the F row shows.

Preferably the tiling of View tile display buffer lied garbage collector algorithm 70 administration view shows the use (Figure 10 A, 10B, 10C) of storage.Garbage collector is safeguarded View tile display buffer lied 60 (Fig. 1), makes View tile display buffer lied use and is lower than the storage restriction, and the storage free space is higher than the free space restriction.Garbage collector constantly scans buffer memory, size that the tiling of accumulative total view shows and time statistics.Reduce cache size if desired, then garbage collector selects the minimum view tiling of deletion visit in the recent period to show, is positioned at limited field until cache size.Garbage collector moves with low priority, reduces the interference to even more important system task as far as possible.The restriction of storage free space is designed to the safe limit that anti-locking system uses up storage.The inspection of free space restriction is regularly carried out, if surpass this restriction, garbage collector becomes the emergency system task so, with the high priority operation, limits greater than free space until the storage free space.

The digital document file can be stored in other server in WEB server or the network.Image file is general as the digital document management that attribute information is arranged, and these information stores are in the document of document storage 90.The digital document management system can independent operating, perhaps moves with the image view server software.The digital document file can be scanning image file or non-scanned document file.If the digital document file is non-scan format, so it is processed into black and white, gray scale or chromoscan image and browses.

Figure WEB browser on the client workstation 10 receives html data from image view server 210, this server comprises needs to show the hyperlink that shows with formative view tiling in the buffer memory 60, it has described the outward appearance of tiling demonstration to generate image view.The WEB browser must show 220 from each view tiling of this view of image view server retrieves when beginning.After initial views, in case the last view of view and same ratio is overlapping, then the WEB browser is preferably from WEB browsers local buffer memory 210, rather than the view tiling that shows before the server retrieves shows.

The performance of document browsing and availability can utilize the demonstration gradually of tiling displayed image to improve.Utilization allows the types of image file formats of browsing roughly of image to be shown when the other parts of downloading images content, can see the rough view of document quickly.

Because most of WEB browsers once only transmit 1 to the 4GIF image, not to show that all the view tilings in the view formation show simultaneously gradually usually.Therefore, realize preferably showing gradually that provide algorithm on the client computer to accept optionally another data layout, its allows entire document browsing area screen to utilize progressive demonstration, and still have the tiling demonstration on the client computer and the advantage of buffer memory.This can be realized by the WEB browser environment of the algorithm that adopts Java, JavaScript or ActiveX technology to write.Utilize client software to improve client browser, can adopt optional view tiling display format and view compression algorithm that the further improvement of performance is provided.Significantly example is to use Portable Network Graphics (PNG) form of optimization, it requires image view server and client computer only to transmit a shared visual head, it shows public by all view tilings, sending the compressed image data of the low resolution of each view tiling demonstration then, is the pictorial data of the full resolution of each view tiling demonstration afterwards.

Except the view tiling array of display that shows the request view, html data also comprises such hyperlink, the tool bar that they generated sends request to change the method when front view for the user provides to server, this change comprises the increase and decrease scale of view, change view area, perhaps change the view size.This hyperlink will be pointed to and work as front view, and comprise such operational code, the new view of hyperlink layout that these operational codes require the image view server to select according to the user.

Method of the present invention, equipment and software item provide a kind of improved client server architecture that adopts figure WEB browser to visit the image view server, and it can use network effectively.Tiling shows and buffer memory based on the image of method for optimizing in utilization, when the user selects the new view of the image that received and browsed, only needs the less relatively data of quantity forwarded.The image that server will be asked with the form of request sends to workstation, allows the local copy browse view based on image file then.The image view server can provide better scheme in the following manner: utilize low-cost visual WEB browser, make that workstation can accesses network image view server, provide the image view that can show by figure WEB browser on workstation.For example, if are 8 megabytes with the size of the E-size engineering drawing scanning image file of per inch 200 pixel black and white imagings.Utilize common data compression, image file can be reduced to the 250K byte.The low bandwidth 28.8K baud MODEM network that utilization has the about 3K handling capacity of per second connects, and image file is sent to workstation uses to browse and need 83 seconds (250KB/3KB/ second).Utilize the image view server, only transmit the pictorial data that needs demonstration.896 take advantage of the exemplary view of 512 pixels to take advantage of the 128 pixels * 128 pixel view tiling of 4 arrays to show and form by 7.The tiling of black and white view shows that with the compressed format transmission it generally generates the tiling demonstration that each is 512 bytes, the about 14K byte of whole view (0.5KB * 28 tilings show), and transmitting need about 4.8 seconds (14KB/3KB/ second).This views browsing method can provide response preferably for the user, and lower to the network connection request.LAN (Local Area Network) generally adopts the medium of 10M bits per second, so the efficient of image view server improves and is not obvious.But, if 10M bits per second network share by 100 users, each user's the average bandwidth 12.5K byte per second of only having an appointment so, like this, the efficient of image view server is still considerable.Another benefit of image view server is that even the size of view image increases, data transmit size and still keep constant.If because of image is big, resolution is higher or compressibility is lower, the image file size is bigger 4 times than last example, then the network load of image view server will remain unchanged, and the network load of conventional image browser will increase to original 4 times.

The present invention has reduced the software purchase cost, uses because figure WEB browser is common cheap workstation, and the expense of WEB browser normally workstation is used for the required cost of other purpose, and is included in the workstation operating system in many cases.The cost of server software can be shared by hundreds of client workstation.

The software administration cost can reduce by figure WEB browser and server software, the former is that the common workstation of being managed is used, thereby eliminated additional special purpose workstation software application, the latter only need be at central server, rather than manages on each workstation.

On all routine work station types, and miscellaneous equipment, for example all be equipped with figure WEB browser on notebook, palmtop computer, network computer and the WEB TV adapter, thereby a kind of scheme that can widely adopt is provided.

To those skilled in the art, obviously under the prerequisite that does not depart from the scope of the invention and spirit, multiple improvement and variation can be arranged to network view image server and image view server method.To those skilled in the art, consider disclosed explanation of the present invention of the application and practice, other embodiments of the invention also are obvious.These explanations and example only are exemplary, and the real scope and spirit of the present invention are limited by follow-up claims.
