Embodiment 1：
Fig. 2 is the flow chart for the virtual desktop image transfer method that the embodiment of the present invention 1 provides, and specifically includes following processing
Step：
The time for the drawing for order that the operation of step 201, monitoring virtual opetrating system generates.
In this step, user can be used the input instructions such as keyboard, mouse, be led to by the virtual desktop shown in terminal
The interface channel crossed between terminal and server is sent to server, for the resource using virtual opetrating system, pseudo operation
System can operate according to corresponding to being carried out the specific instruction that server receives, and in general a, operation may generate multiple paint
Figure instruction, such as：In the application such as Microsoft Office Access, Microsoft Office Excel, process is used
In an operation can produce thousands of drawing for orders.
Step 202, determine time interval between the drawing for order of continuous predetermined number whether all less than it is default when
Between be spaced, if not, into step 203, if it is, into step 204.
Wherein, the predetermined number and the prefixed time interval can flexibly be set according to practical experience and needs, example
Such as, the predetermined number could be arranged to 50, and the prefixed time interval could be arranged to 0.5ms.Between time between drawing for order
Difference between the time for being generation present figure instruction and the time of last generation drawing for order.
In this step, the number that prefixed time interval can be less than to the time interval between drawing for order counts,
For example, when the time interval between first drawing for order and second drawing for order is less than prefixed time interval, by number
Count is calculated as 1, when the time interval between second drawing for order and the 3rd drawing for order is less than prefixed time interval,
Number count is increased into by 1, i.e. count=2, by that analogy.
Because in one application, an operation sets appropriate predetermined number can there may be thousands of drawing for orders
Effectively to judge the generation of intensive drawing for order, the erroneous judgement of intensive drawing for order is prevented.
Step 203, when the time interval between the drawing for order of continuous predetermined number at least one time interval not
During less than prefixed time interval, continue the time of monitoring generation drawing for order.

Specifically, corresponding opening position is drawn this and painted in total drawing area using the command code in the intensive drawing for order
Bitmap in figure instruction, such as：Mapping operation corresponding to command code can be copy, filling etc..By all intensive drawing for orders
After completing, total bitmap corresponding to all intensive drawing for orders is obtained, total bitmap represents the aobvious of all intensive drawing for orders
Show result.Such as：When using Microsoft Access, Microsoft Access are generating a white rectangular patterns
When, it is the rectangle that white is depicted as by thousands of white lines, each lines is corresponding to generate a drawing for order, each
Drawing for order includes corresponding lines bitmap, copy function code, the positional information of the lines, sentences when according to step 202-204
When thousands of individual drawing for orders of disconnected birth are intensive drawing for order, according to the sequencing for generating each drawing for order, to each
Drawing for order is drawn in corresponding opening position respectively corresponding to individual white line, obtains white rectangle, that is, is obtained all close
Collect total bitmap corresponding to drawing for order.
Step 209, generate drawing for order corresponding to total bitmap.
Drawing for order corresponding to total bitmap that is, an equivalent drawing for order corresponding to all intensive drawing for orders,
Including total bitmap, total drawing area and command code, because total bitmap is the display result that represents all intensive drawing for orders, because
Total bitmap is carried out copy function by this, and the command code is copy.Largely intensive paint is substituted using equivalent drawing for order
Figure instruction, can be greatly decreased the drawing for order quantity for being sent to terminal.Exemplified by drawing white rectangle in step 208, by several
Each self-corresponding drawing for order of thousand white lines generates a total bitmap i.e. white rectangle, to should white rectangle generation one
Bar drawing for order.
Step 210, drawing for order corresponding to total bitmap is sent to terminal.
In this step, terminal is sent to after drawing for order corresponding to total bitmap can be compressed to processing.That is,
Terminal is sent to after a drawing for order corresponding to white rectangle is compressed into processing, rather than respectively by each white wire
Drawing for order corresponding to bar is sent to terminal after being compressed processing.
Step 211, when drawing for order corresponding to terminal receives total bitmap, drawn and referred to according to corresponding to total bitmap
Virtual desktop image is drawn in order, and is shown by display screen.
If drawing for order corresponding to total bitmap that terminal receives is handled through overcompression, can first be decompressed
Contracting is handled, and obtains drawing for order corresponding to total bitmap.
Further, after it is determined that the operation of virtual opetrating system generates intensive drawing for order, the drawing for order of server
Detecting module continues to be monitored the time interval between drawing for order, when the operation generation for monitoring virtual opetrating system
When time interval between continuous intensive drawing for order is not less than prefixed time interval, stop buffering intensive drawing for order, will
The drawing for order being subsequently generated is sent respectively to terminal, i.e., when the drawing for order monitored is no longer intensive, due to may be one
Seldom drawing for order is produced in individual predetermined period, drawing for order quantity can take a small amount of network bandwidth, then will need not paint less
Figure instruction is cached, and each drawing for order can be sent respectively into terminal.Now, notified by drawing for order detecting module
The intensive drawing for order of buffer module terminates, if not reaching the time of a predetermined period also now, i.e., in distance service device
Processing module reads all intensive drawing for orders stored in buffer module and has not timed out predetermined period 30ms, buffer module
30ms timers will be started immediately, the processing module in server is to all intensive drawing for orders for currently being preserved in buffer module
The processing of above-mentioned steps 206- steps 210 is carried out, after the completion of processing, buffer module Off Timer, and no longer buffer intensive
Drawing for order is untill drawing for order detecting module detects and generates intensive drawing for order next time.
The method provided by the above embodiment of the present invention 1, because the operation when virtual opetrating system generates intensive drawing
During instruction, first by the storage of intensive drawing for order into buffer module, and periodically by the intensive drawing for order pair in buffer module
A bitmap should be generated, the drawing for order of a bitmap is sent to terminal, i.e., by multiple intensive drawing for orders to generation one
