For in correlation technique, two kinds of scenes of mouse action virtual desktop, propose corresponding image processing method respectively in the present embodiment, such as, for the first, that is, in most of occasion operator roll mouse during key, the order of multiple middle button of mouse can be sent continuously, the refreshing at all corresponding interface of order of each middle button of mouse.When therefore causing virtual desktop image change when there is middle button of mouse operation, temporarily do not send images on the screen of client, but after monitoring, whether have middle button of mouse to operate arrival, if not, the image of the change caused by this middle button of mouse is sent on the screen of client.After last middle button of mouse order arrives, virtual desktop is analyzed (such as to image change part, to line by line scan coding analysis), and the image that a upper width is sent on the screen of client compares---draw changing unit and do not have vicissitudinous part.Only the content of changing unit is sent to client (i.e. thin terminal); For the second, namely the action of a browsing document is browsed for pinning left mouse button dragging scroll bar, and such mouse often holds in the palm and once will produce corresponding refreshing.The Position Approximate of scroll bar is judged in the application (such as WORD program board program) that virtual desktop belongs to according to the window of current active---such as on the right of window.When mouse move (mouse position and scroll bar interval coincide)+left button arrived by the action pinned and cause content change in active window time, temporarily do not send images on the screen of client, but whether have after monitoring mouse move+left button continued to arrive by the action pinned, if not, the image of the change caused by this being operated is sent on the screen of client.When last mouse move+after left button arrived by the action command pinned, virtual desktop is analyzed (such as adopting coding analysis of lining by line scan) image change part, and the image that a upper width is sent on the screen of client compares---and draw changing unit and do not have vicissitudinous part.Only the content of changing unit is sent to client.It should be noted that, for above-mentioned two kinds of mouse actions, if thin-client is touch panel device, the slip pointed on touch panel device also can be translated into the rolling operation of middle button of mouse, and above-mentioned processing mode is still suitable for.
Below the virtual desktop image procossing scheme of the embodiment of the present invention is described.
When adopting such scheme to carry out virtual desktop image procossing, can first judge the application program of virtual desktop current active window, application type according to the application program of current active window judges whether to use above-mentioned processing scheme, such as, following comparatively simple determination methods can be adopted, the operating system of current main use Microsoft's Window, when the Windows in virtual desktop produces new window, virtual desktop can obtain the application type of new window by the character string in window title---such as, be applied as MicrosoftWord, MicrosoftExcel, notepad, IE etc., the type of application can be judged according to the character string in this window title, thus determine whether adopt above-mentioned processing mode.Illustrate below.For application---such as MicrosoftWord conventional in current windows system, MicrosoftExcel, notepad, IE etc., these application have scroll bar, and the position of scroll bar is very fixing: (1): up-down scroll bar is all positioned at the vertical elongated zones of the low order end of window; (2): left-right scroll bar is all positioned at the horizontal shape elongated zones bottom of window; Virtual desktop is easy to the general coordinate calculating the interval region in application window of scroll bar.Therefore, be adopt rolling operation to browsing of above-mentioned application, namely can adopt the image procossing scheme of above-mentioned virtual desktop.
Illustrate respectively below in conjunction with above-mentioned two kinds of mouse action scenes.
The operation scenario of middle button of mouse: when a window becomes active window, the image of current window is issued thin-client by virtual desktop, and thin-client completes display on interface.Meanwhile, virtual desktop and thin-client preserve in window this image simultaneously headed by width image.Mode below by middle button of mouse carries out rolling change to image, and namely when virtual desktop receives the order of middle button of mouse, if virtual desktop creates image change, then virtual desktop carries out com-parison and analysis process by the change of image;
S1, process, whether in the scope of current active window, if not in the scope of active window, is not then continued in the interval that image change occurs;
S2, if the interval of generation image change is in the scope of active window, then continues following process: carry out buffer memory to new image, and can judge that new images moves for there occurs during upper piece image or moves down according to the direction of rolling.Then the side-play amount (such as the height of 10 row pixels) that video in window rolls is calculated, side-play amount (such as scroll up 10 row pixels) is sent to client---this amount of information is very little, takies negligible to the network bandwidth;
S3, thin-client carries out display update according to the rolling side-play amount sent---and such as scroll up the original image being buffered in thin-client 10 row pixels, because virtual desktop is not sent to thin-client the image of changing unit (newly carrying out bottom of window 10 row pixel), thin-client can adopt the 10 row pixels of the mode of blank gradual change on interface bottom display window, to operator with the balance of visual experience aspect;
S4, virtual desktop continues whether have new middle button of mouse order to arrive in monitoring at the appointed time.If there is new middle button of mouse to arrive, then circulation proceeds the operation of S2, S3 step above;
S5, after not having the operation of middle button of mouse to arrive, accumulation is calculated up-to-date image (after not having middle button of mouse to arrive) and first width image (before first middle button of mouse arrival) contrasts, calculate side-play amount (i.e. above-mentioned accumulative position offset), the information of side-play amount (height of the 80 row pixels that such as, scroll up)+emerging 80 row pixels is sent to thin-client;
S6, thin-client will be buffered in local first width image (before first middle button of mouse arrival) and upwards offset 80 row pixels, then superpose the information of emerging 80 row pixels, form new image and be buffered in thin-client;
S7, replace the operation in the middle of mouse in touch-screen with finger sliding, above-mentioned handling process is still suitable for.
Mouse moves+operation scenario of left mouse button: move when virtual desktop receives mouse+left mouse button press order time, if virtual desktop creates image change, then virtual desktop carries out com-parison and analysis process by the change of image;
S1, the interval that image change occurs whether in the scope of current active window, if not in the scope of active window, then ended process; Judge that the position of mouse is whether between scrollable area, if not between scrollable area, method described in the invention is inapplicable simultaneously.If active window there occurs change and mouse current location between scrollable area, then use the method for S2 ~ S5 step below;
S2, virtual desktop is buffer memory new images first, and then virtual desktop sends the order of rolling to thin-client, and thin-client adopts between blank+up time rolling figure calibration method viewing area, and operator is understood, and the action dragging scroll bar is being had an effect;
S3, virtual desktop continue whether to have in monitoring at the appointed time new mouse move+the left mouse button order of pressing arrives.If there is new middle button of mouse to arrive, then circulation proceeds the operation of S2 step above;
S4, when do not have mouse move+after the operation of left mouse button arrives, accumulation is calculated up-to-date image (do not have mouse move+after left mouse button arrives) and first width image (first mouse move+left mouse button arrival before) to contrast, calculate side-play amount, the information of side-play amount (height of the 200 row pixels that such as scroll up)+emerging 200 row pixels is sent to thin-client;
S5, thin-client will be buffered in local first width image (before first middle button of mouse arrival) and upwards offset 200 row pixels, then superpose the information of emerging 200 row pixels, form new image and be buffered in thin-client.
Below in conjunction with handling process schematic diagram, the preferred embodiment for the present invention is described.
Figure 10 is first active window schematic diagram in virtual desktop image processing method according to the preferred embodiment of the present invention, as shown in Figure 10, in virtual desktop after there is new active window, buffer memory is carried out to the image of active window, and being sent to thin-client, thin-client carries out buffer memory to the image of window simultaneously.
Figure 11 is that video in window rolling side-play amount calculates schematic diagram in virtual desktop image processing method according to the preferred embodiment of the present invention, as shown in figure 11, when middle button of mouse causes viewing area to occur to roll change, image new under the first buffer memory of virtual desktop, then compare with original image, calculate rolling side-play amount, the method for calculating is as follows:
(1) 1st row (N+1 in Figure 11 capable) of new images in viewing area and original image is used to compare at the 1st row (1 row in Figure 11) of viewing area, if just different and original image compares at the 2nd row of viewing area, until find identical (supposing 11st row of original image in viewing area);
(2) 2nd ~ X (X can the configure) row of new images in viewing area and (12 ~ 10+X) of original image is used to contrast line by line, if whole identical explanation side-play amount is found correctly.Otherwise continue the search procedure of (1) step---restart comparison with new images at the 1st row of viewing area and the 12nd row of original image.
Figure 12 is that thin terminal draws viewing area schematic diagram according to side-play amount in virtual desktop image processing method according to the preferred embodiment of the present invention, as shown in figure 12, side-play amount is issued thin-client by virtual desktop, and thin-client repaints window viewing area according to side-play amount.
In virtual desktop monitoring at the appointed time, whether (can configure, such as 0.2 second) has new middle button of mouse order to arrive.If there is middle button of mouse instruction to arrive at the appointed time, then proceed Figure 11, the operational processes shown in Figure 12.If do not have middle button of mouse instruction to arrive at the appointed time, then proceed following process.
Figure 13 is that thin terminal draws viewing area schematic diagram according to side-play amount+constant interval in virtual desktop image processing method according to the preferred embodiment of the present invention, as shown in figure 13, calculate accumulation side-play amount, side-play amount and emerging pixel column are sent to thin-client, and thin-client repaints window viewing area according to the interval of side-play amount+change.
It should be noted that, for the method for operation (dragging scroll bar) pinning left mouse button+rolling mouse, substantially similar with middle button of mouse, difference is that virtual desktop is in the process of mouse movement, no longer calculates the side-play amount of each movement but stops the side-play amount of mobile rear calculated population at mouse.The thin-client hour hands that whole interface display rotates in mouse moving process represent that interface is in the process of refreshing.
