Description
Technical field
The present invention relates to EDP technology, especially relate to a kind of browsing file and localization method and system.
Background technology
Along with the progress of infotech, computer application is increasingly extensive, and the memory capacity of computing machine also grows with each passing day, and the size of file also becomes increasing, more and more longer in the computing machine.Comparatively speaking, graphoscope is because the restriction of size, become the obstacle that file shows, this is because computer screen can only show the part with the screen size corresponding file, page or leaf or other parts of browsing other just need the action adopting page turning or roll, thus up and down or about switch the page of file.
Demonstration for file, it is a well application that the scroll bar relevant with file system is set on indicator gate, can adopt modes such as keyboard or cursor of mouse to operate scroll bar, the modes such as scroll key of roller, Trackpad (TRACK PAD) scrollable area and the touching control rod (TRACK POINT) of the action of rolling also are provided on the mouse kind equipment simultaneously, and these can increase the convenience that page turning is rolled.
On this basis, the convenience of page turn over operation has disclosed the multiple technologies scheme when showing for improving file in the prior art.
For example United States Patent (USP) the 6th, 166, and the technical scheme of No. 721 announcements provides other switch on mouse, and one is used for turning over, and one is used for down turning over, and another one is used for selecting, but button too much neither be very convenient.United States Patent (USP) the 5th, 726, No. 687 and United States Patent (USP) are concentrated the page turning action when solving the mouse drag motions for the 5th, 611, No. 060, decide the speed of page turning tumbling rate according to the position that pulls.United States Patent (USP) the 6th, 353 is provided with the mechanism that a height according to input signal decides the tumbling rate speed No. 432 in mouse.At United States Patent (USP) the 6th, 738, in No. 045, by detecting the control that the motion of rolling is quickened to roll.
But, above-mentioned prior art is not all considered the relation of file size and tumbling rate, if file is bigger, because in internal memory, can't place whole file, therefore the part of file need be placed in the slower hard disk of access speed or other external memories, call data then from hard disk, tumbling rate is also with slack-off so.Particularly under some opposite extreme situations, the speed that the page rolls does not catch up with the tumbling rate of mouse roller, this just certainly will cause that the action of rolling of some mouse rollers is arranged is to be in waiting status in the event queue table, waits until after the last action of rolling is finished always and just carries out.
Consider above-mentioned defective, United States Patent (USP) the 5th, 900, the technical scheme that discloses for No. 876 is a kind of mechanism of can page turning browsing, and adopts compress algorithm, shows in the assigned address virtualization, comes to turn in the simulating reality life action of book.That is to say that the key message in the file is extract, and virtualization is presented on the display.
United States Patent (USP) the 5th, 838, the method that adopts another that preview is provided No. 320 further, provides the speed of preview to accelerate to browse browsing in the frame.And, in No. 370, the information of browsing is also noted, so that locate fast when browsing next time at United States Patent (USP) the 5th, 757.
But above-mentioned three kinds of prior aries can take the display space of screen, have overlapping with source document, cover on the source document, cause checking that source document is influenced by some, and key is to adopt the mode of these two kinds of browser documents can't directly remove the overall picture and the edit-modify file of viewing files under the state of browsing.After finding file, could be at the state that the opens file edit-modify that goes down, thus there is inconvenience and influences operating rate and efficient.
The mechanism that careful investigation file rolls and browses, the slow-footed main cause of browse displays of big file comprises: 1, processor and storer fill order are slow; 2, the event queue table is that order is carried out, must must wait an incident to be finished after, just carry out next incident.
With regard to first reason, this is a long-term contradiction.In fact, the processing speed of processor and storer is in continuous improve, but file size is also increasing, and the performance that therefore improves hardware processor and storer is not to the slow-footed solution completely of aforementioned browser document.On the existing hardware technical merit, the software that goes to optimize some display files is good method, such as picture browsing professional software ACDSee software, when browsing rest image, by the optimization of software and suitable Image Compression, the feasible file speed of calling in is very fast, the photo of calling in about 2M size usually only needs less than in 1 second, but the full screen projection for dynamic video image is unable to do what one wishes with regard to some, the PICASA of this point software GOOGLE Inc. just relatively rationally can be by the mouse roller browsing video image file that rolls immediately.But along with the capacity of handling file is increasing, the benefit that software optimization obtains is still limited, and the stand-by period when rolling operation is inevitably, and the stand-by period is more and more longer along with the file change is big.
Seeing also Fig. 1 and Fig. 2, is that the mode that the employing event queue table of prior art is carried out in proper order realizes the synoptic diagram that file shows.
Consult Fig. 1, turn over instruction to the event queue table under the mouse roller input, be pressed in event queue table bottom, operating system ejects each incident in proper order from the top of incident queue table then, and the incident of each ejection is handled, and promptly turns over processing under the file, because file is bigger, therefore need wait for a period of time when turning over down, after being finished, eject second incident again.
The mode that the event queue table is carried out in proper order has some defectives, for example the processing time long, inefficiency.This is because some actions of rolling in the middle of in fact are that the user does not want to see in fact or do not need to see in detail, just can carefully see after only finding file destination; In addition because the situation that has the incident queue table to wait in line, the user is when waiting, can all the time turn over down to expect to reach fast file destination, but also can occur having climbed over the file destination situation of page turning back then when user's page turning, even can occur more than once back and forth, waste the more stand-by period.
Consult Fig. 1 and Fig. 2 in the lump, file destination is in the position of n-4.The user turns under file 1 begins, at waiting time, the user is by the action of turning under the mouse roller, but the user is in the process that pending file is opened, turn under the meeting continuously, when seeing file destination by the time, mouse roller has but climbed over head, therefore turn over two lattice to last time with mouse roller again, turned over incident on forming two.During this, computing machine does not also know that n-4 is exactly the position at the desired file of user place, prior art is to carry out like this: turn over processing under continuing to carry out, up to executing the n-2 step, carry out then and turn over the instruction incident on two, turn under middle any execution, on turn over time of wait, one is not all missed, carry out, the incident in the event queue table is cleared, so the time that the user need wait for is to open file 1 in the same old way, file 2, file 3...... file n-4, file n-3 is until file n-2, and then add the n-3 that opens file, the summation of the time of file n-4.
And in fact, the user spends the stand-by period in each file page turning between 1-n to there is no need fully, because user's target is to see the locational file of n-4, therefore only need see that n-4's is general, just can be positioned at once on the position of n-4 then, and there is no need to continue to carry out n-3, n-2, Deng under turn over, on turn over from n-2 to n-3 the action of n-4.The way of these prior aries all is the stand-by period the waste user.
Summary of the invention

Embodiment
Main thought of the present invention is: in the browsing file application system, in the instruction of accepting the event queue table, the a plurality of incidents of disposable ejection in the event queue table, reading preanalysis in advance handles, when in the incident of reading in advance, detecting opposite mutually page turning incident, do speed-down action, promptly positive and negative page turning incident is cancelled out each other yet, the incident after the counteracting is not carried out any action; And when a plurality of repetition page-turning instruction was arranged in the incident that detects ejection in the schedule time, in the preview of display on display file, accelerating the speed of browsing file, and actual big file did not really show, saves user's stand-by period; And when recurrence rate when being not very high, according to normal big browsing file mode browser document.
Seeing also Fig. 3, is the process flow diagram of browsing file of the present invention and localization method.
Step S310 obtains the incident in the event queue tabulation in batches and divides the page turning incident that detects wherein.
That is to say, in the instruction of accepting the event queue table, a plurality of incidents of disposable ejection in the event queue table.
Described event queue table is to be placed in the Installed System Memory in the specific zone, and the input of external unit is pressed in the bottom in proper order as the input of system event queue table, is to eject a collection of incident when eject at the top.
Step S320 subsequently, carries out preanalysis to the aforementioned incident of obtaining and handles, and realizes the demonstration of file according to the preanalysis result.
Step S330 if there is opposite incident mutually, then offsets reciprocal incident and do not carry out.
Continuous page turning action is arranged in the incident that is ejecting and have opposite page turning to occur continuously, that is to say, the identical page-turning instruction of continuous appearance is arranged in the event queue table and, doing the processing of slowing down followed by in the continuous rightabout page-turning instruction.
Step S340 if the number of the consecutive identical incident that exists in the schedule time reaches predetermined value, then quickens the processing to incident, the preview of display file.
When having the identical page turning of direction that is no less than predetermined value to move in the incident that is ejecting, that is to say, in the event queue table,, do and quicken to handle with in the identical page-turning instruction of upper frequency appearance.
Step S350 then carries out normal browsing file mode browser document for other incident.
Seeing also Fig. 4 and Fig. 5, is the synoptic diagram that quickens to handle in the method for the present invention.
Consult Fig. 4, system is when file pointer points to file 1, and system begins to open file 1, and this process stand-by period of opening the process of each file and close file is longer.
Consult Fig. 5, through the preanalysis of incident is handled, generate assisted instruction, file pointer is directly skipped 3 files after receiving assisted instruction, and this moment is display file 2,3 and 4 preview file successively.
Subsequently, consult Fig. 4 once more, file pointer points to the 5th file, and close file 1 then, opens the 5th file, and the middle process of opening close file 2,3,4 has been omitted with regard to the whole province.
That is to say, in case after satisfying the condition of quickening to handle, such as the following incident of turning over that occurs continuously in the time at a paragraph qualification more than 3, then the All Files that will point to the pointer under this catalogue extracts characteristic element, (method that forms preview file can be seen prior art to form preview file, also can under this catalogue, be ready to the preview file of All Files in advance, when waiting for the preview conditions maturation, activate preview).
Seeing also Fig. 6, is the synoptic diagram that slows down in the method for the present invention and handle.
When detecting opposite incident, begin to offset opposite incident respectively from reversal point so, such as n-3 among the figure toward both sides, n-2 and n-1, n are just in time opposite, therefore these four incidents are offset, be left intact in file operation, save the processing time, file pointer rests on the n-4 file.
Seeing also Fig. 7, is the block diagram of the unified embodiment of browsing file of the present invention and positioning systems.
This document display system comprises page turning incident sorter 610, counter 620, page turning trafficator 630, timer 640, file operation controller 650.
Page turning incident sorter 610 is used for dividing the page turning incident that detects from the incident that incident queue table 500 is ejected in batch.
Wherein, when the page turning action of this direction is arranged in the incident that is ejecting, increase the numerical value of counter 620; When having the opposite page turning of this direction to occur in the incident that is ejecting, doing slows down handles, and reduces the numerical value of counter 620.
650 bases of file operation decision package comprise the instruction of quickening browsing instructions or normal page turning from the information spanned file operational order of counter 620 and page turning trafficator 630.
In preset time, when the number of the page turning of a certain direction action reaches predetermined value in the incident that ejects, that is to say, when in the event queue table, identical page-turning instruction occurring continuously with upper frequency, do and quicken to handle, activate preview mechanism, open it until arriving file destination; And when recurrence rate when being not very high, according to normal big browsing file mode browser document.
Seeing also Fig. 8, is the process flow diagram of an embodiment of method of the present invention.
Step S811 carries out the go-no-go of page turning incident.
Step S812 starts timer.
Step S813, the enabling counting device.
Step S814, whether the page turning incident of equidirectional; If then enter step S815; If not, then enter step S816.
Step S815, counter adds one.
Step S816, counter subtracts one, gets back to step S813.
Step S817, whether timer reaches timing time; If then enter step S818; If not, then get back to step S813.
Step S818, whether counter reaches preset value; If not, then enter step S819; If then enter step S820.
Step S819 carries out normal page processing.
Step S820 activates the preview of file.
Step S821 quickens to browse.
Certainly, the present invention is not limited to the foregoing description, and other variation can also be arranged.For example, can adopt two counters to write down the number of the page turning incident of different directions respectively, wherein when the direction that detects the page turning incident changed, then event counter was counted; The file operation controller value of these two counters relatively then, promptly the number of the page turning incident of comparison of aforementioned different directions obtains the number difference of page turning incident, thereby obtains the number and the direction of the page turning incident of remaining a certain direction.And whether reach predetermined value according to the number of this remaining page turning incident in the schedule time and decide and quicken to browse or normal page turning.
For ease of understanding the present invention, the present invention will be described in detail below in conjunction with example.
Example 1
This example is used for the processing of logarithmic code image file, general digital photograph is if the digital camera of 500 everything elements of common usefulness, adopt the file layout of TIFF can reach about 14,000,000, and generally adopt the file of JPG form, also have about 2,000,000, if also have some video files, no matter adopt which type of form, file size is bigger certainly than rest image, generally arrives hundreds of about million tens, and therefore the editor that browses to these files has the higher requirement of ratio to system really.
In an embodiment of the present invention, adopt the method for previewing of the MEGAVIEW of prior art XEQUTE SOFTWARE company, the preview to various image files is provided.
System and method of the present invention is then controlled the time point that activates preview and finish preview, and control preview file and the overlapping demonstration of actual file.The file that is to say preview is be suspended in actual file top, activates preview when condition is browsed in satisfied acceleration, when the page turning action is slowed down, adopts common browsing mode.How preview file is suspended in also can be with reference to prior art (with reference to the perspective technology of Microsoft's Window) on the actual file.
In the timing range of timer,, start the function of fast browsing so, if do not surpass, then according to the normal mode page turning if counter surpasses setting value.
Example 2
Example 2 is roughly the same with example 1.Different is, under file directory, deposits the preview file of all image/video files, like this when needs quicken to browse, only need activate preview file just passablely, and additive method and example 1 are similar.
In sum, the present invention mainly proposes the method and system of the page turning rolling of a kind of fast browsing file and locating file, makes the user when a plurality of big files are browsed in page turning, and the time of wait is the shortest.
The present invention changes the navigation mechanism problem in the existing big browsing file application system, mode of operation to the event queue table is such, the event queue table is to be placed in the Installed System Memory in the specific zone, and the input of external unit is pressed in the bottom in proper order as the input of system event queue table, be to eject a collection of incident when eject at the top, in page turning incident sorter, do preanalysis earlier and handle, extract the feature of key operation, analyze the incident instruction of relevant page turning up and down, handle.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
