B, obtain the dynamic picture information in current rectangle zone, set up the bitmap structure chained list and write down rectangular area, place dynamic picture information according to the dynamic picture information of being obtained; And
C, traversal bitmap structure chained list are preserved and demonstration dynamic picture information.
Also comprise left mouse button Up message and the Down message of obtaining the user before the described steps A, and determine the step of the rectangular area of needs intercepting according to the left mouse button Up message of being obtained and Down message.
Dynamic picture information among the described step B comprises the frame number information of dynamic picture.
Also comprise the step of obtaining current mouse information and judging whether to cancel the intercepting dynamic picture according to the mouse information of being obtained behind the described step B.
Described step C also comprises traversal bitmap structure chained list, the step that writes shear plate and preserve according to the sequence mode with set form.
Described step C also comprises and obtains the window handle data, obtains the concrete window object in dynamic picture place according to the window handle data, and according to fixed format carries out correspondence according to dynamic picture place window object and shear plate and duplicate the step that generates the sequence of pictures chained list.
Described step C also comprises and obtains the rectangle size data, generates demonstration context with the current device compatibility according to current device context in internal memory, traversal sequence of pictures chained list, and the byte stream in the sequence of pictures chained list write show contextual step.
Described step C also comprises according to api function generation temporary file handle, flows to the step that luggage carried and be saved to the indicated corresponding space of temporary file handle to showing the data byte in the context.
Described step C also comprises the picture file frame sequence in the combination temporary file handle, generates the dynamic picture format picture according to the dynamic picture form, utilizes the picture loading module to load the step of dynamic picture to specified window object and demonstration.
Described step C also comprises the step of preserving or send dynamic picture according to specified path.
Beneficial effect of the present invention is as follows:
Use a kind of intercept method of dynamic picture of the present invention, the user not only can carry out the communication of ordinary text message, and can intercepting page in chat process or the dynamic picture seen in other places, send separately or merge text and send with dynamic picture, the communication of greatly enriching between the user is experienced, allow the good friend of oneself share the interesting dynamic picture content of being seen at any time with oneself, for instant communication users brings favorable user experience.

Embodiment
The present invention is directed to the defective of prior art, the method that proposition can make terminal can carry out the dynamic picture intercepting and preserve is explained in detail main realization principle of the present invention and embodiment thereof below in conjunction with accompanying drawing.
Please refer to Fig. 2, this figure is the process flow diagram of a kind of intercept method of dynamic picture of the present invention, and its main implementation procedure is as follows:
Step S21, definite rectangular area that needs intercepting;
Utilize the Hook Mechanism of Windows to obtain user's left mouse button Up message and Down message, and determine the rectangular area of needs intercepting according to left mouse button Up message and Down message;
Described left mouse button Up message comprises horizontal ordinate and the Y value of current mouse in the relative screen upper left corner;
Described left mouse button Down message comprises horizontal ordinate and the Y value of current mouse in the relative screen lower right corner.
Step S22, judge in the above-mentioned rectangular area that needs intercepting whether comprise dynamic picture;
Utilize device context (the Device Context of Windows, DC) application programming interfaces (Application Program Interface, whether API) function comprises according to current rectangle place screen area the pixel data of continuous variation judges in the rectangular area, current place whether comprise dynamic picture;
If rectangular screen zone, current place does not comprise dynamic picture, execution in step S23 then sets up the bitmap structure consistent with above-mentioned rectangle size and utilizes the Windows shear plate that the on-screen data of current location rectangular area is copied to above-mentioned bitmap structure and preserve and transmit;
Step S24, intercepting dynamic picture;
If rectangular screen zone, current place comprises dynamic picture, utilize the api function of the device context of Windows to obtain current rectangle zone dynamic picture information, and set up the bitmap structure chained list according to the dynamic picture information of being obtained, record dynamic picture information;
Described dynamic picture information comprises the frame number information of dynamic picture;
Described bitmap structure chained list is to set up in internal memory according to the frame number information of dynamic picture, be used to write down the data byte information of dynamic picture, element in the bitmap structure chained list is corresponding one by one with the dynamic picture frame, and each element writes down the data byte information of corresponding frame;
Step S25, judge whether cancellation intercepting dynamic picture;
Utilize the Hook Mechanism of Windows to catch current mouse information, judge that according to the position data of the current mouse information of being caught mouse is whether in the rectangular area of required intercepting, if current mouse is not in the rectangular area of required intercepting, execution in step S32 then, cancellation intercepting dynamic picture, and the bitmap structure chained list of deletion step S24 foundation; If current mouse is in the rectangular area of required intercepting, execution in step S26 then;
Step S26 utilizes the api function traversal bitmap structure chained list of the shear plate of Windows, writes shear plate and preserves according to the sequence mode with set form;
Step S27 utilizes the api function of the window of Windows to obtain the window handle data, obtains concrete window object according to the window handle data, and according to fixed format carries out correspondence according to window object and shear plate and duplicate and generate the sequence of pictures chained list;
Step S28 obtains the rectangle size data, generates demonstration context with the current device compatibility according to current device context in internal memory, the sequence of pictures chained list that traversal step S27 generates, and the byte stream in the sequence of pictures chained list write the demonstration context;
Described demonstration context is that generate in internal memory according to current device context and the device context current device compatibility;
Step S29 utilizes the api function of Windows file to generate the temporary file handle, and the IPicture interface function that utilizes Windows is to showing that data byte in the context flows to luggage and carries and be saved to the indicated corresponding space of temporary file handle;
Step S30, the picture file frame sequence in the combination temporary file handle generates the dynamic picture format picture according to the dynamic picture form, utilizes the picture loading module to load dynamic picture to specified window object and demonstration;
Step S31 is according to the step of specified path preservation or transmission dynamic picture.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
