When the user needs to perform some kind of graphic editing, for example, the user needs to draw a rectangle on the captured picture, and the continuous editing module 2044 sets the graphic editing command to the corresponding type, the current editing operation correspondingly draws a certain graphic until the user When the editing operation is canceled, the continuous editing module 2044 sets the type of the graphic editing command to be empty so that it is not in an editing state, such as DS_NONE.

In this way, the user can continuously draw a plurality of desired graphics during the editing of the captured image, for example, the user selects the "ellipse" graphic and enters the editing state of the ellipse. At this time, the user can draw any number of ellipses continuously without having to draw one for each. It should be noted that the implementation of continuously editing the same picture in the present exemplary embodiment is merely exemplary, and should not be limited to the above method in practical applications.

Of course, those skilled in the art can appreciate that the above exemplary solutions are only a few typical applications in the present invention, and the editing operation in step 1103 is sufficiently scalable, and new editing can be added according to various personalized needs of users. operating.

Before performing all the steps, the user uses his IM account to log in to the IM software running on the client 200, and opens the chat window and various other windows.

Step 2001: After receiving the screenshot request initiated by the user, obtain and save the attribute information of the current window.

The user initiates a screenshot request through the UI unit 101 in the client 200. The UI unit 101 forwards the request to the dialog control unit 102, and after receiving the request, the latter uses its window save module 1021 to acquire and save the attribute information of the current window.

Step 2002: Extract feature information of the current window and save it.

The dialog control unit 102 further extracts the feature information of the current window and saves it using its window information extraction module 1022. Specifically, the window information extraction module 1022 obtains the handle information of the current window and saves it by using an API for acquiring the current window handle. The window feature value corresponding to the current window is extracted from the handle information.

Step 2003: Determine, according to the foregoing feature information, whether the current window is an IM chat window: If yes, continue to perform step 2004 and subsequent steps; otherwise, the process ends after performing steps 2006 to 2008 and step 2010.

The dialog control unit 102 further uses the determining module 1023 to determine whether the current window is an IM chat window according to the feature information: if yes, proceed to step 2004 to send the user the option to hide the current IM chat window, and the subsequent steps. If no, the process ends after step 2006 to step 2008 and step 2010.

Step 2004: Sending to the user whether to hide the selection information of the current IM chat window, if the user selects to hide, generating and executing a hidden instruction, hiding the current IM chat window on the user interface, and starting the timer while hiding; If the selection is not hidden, the process ends after performing steps 2006 to 2008 and step 2010.

After the dialog control unit 102 determines that the current window is the IM chat window, the UI unit 101 further sends a selection information to the user whether to hide the current IM chat window.

If the user chooses to hide the current IM chat window, the dialog control unit 102 uses its instruction generation module 1024 to generate a hidden instruction and transmits the instruction to the UI unit 101. After receiving the above hidden instruction, the UI unit 101 executes the instruction to hide the IM chat window on the user interface, and while being hidden, the UI unit 101 starts its internal timer.

Of course, in practical applications, the toolbar can also include other editing function buttons, such as restoring the executed operations of the user revocation.

The screenshot editing unit 204 receives the screenshot editing instruction sent by the user to click the toolbar, and determines the content of the screenshot editing instruction; and performs a corresponding editing operation on the captured image according to the content of the screenshot editing instruction. Here, if the user clicks the insertion arrow in the toolbar provided by the UI unit 101, the screenshot unit 103 forwards the above instruction of the user. The screenshot editing unit 204 inserts an arrow on the IM screenshot according to the user's needs.

The image processing module 2043 in the screenshot editing unit 204 can further provide improvements to the above arrow quality. Referring to Figure 22, Figure 22 is a schematic diagram showing the effect of improving the quality of the arrow in the eighth embodiment of the present invention. As shown in Fig. 22, since the arrow is composed of a triangle and a straight line, the triangle portion is prone to distortion during the generation of the arrow, and the image quality is relatively poor as indicated by the arrow 2201 in the figure. In order to solve the above problem, in the embodiment, the image processing module 2043 calculates the coordinates of the other two points of the triangle according to the coordinates and the angle of a triangle vertex, thereby filling the vacant pixel points based on the calculation result, as shown by the arrow 2202 in the figure. As shown, the graphics quality of the triangle is improved. Step 2008: Save the captured image according to the instruction of the user. As shown in FIG. 20, the screenshot unit 103 provides the above-described toolbar having a "save" button in the background of the screenshot using the UI unit 101. After the user clicks the "Save" button on the toolbar, the screenshot unit 103 forwards the corresponding save command to the instant save unit 305, thereby triggering the latter to start, and uses its attribute entry module 3051 to generate an attribute dialog box to display on the user interface. .

Referring to FIG. 23, FIG. 23 is a schematic diagram of a property dialog box according to Embodiment 8 of the present invention. As shown in FIG. 23, after the attribute dialog is generated, the instant save unit 305 uses its attribute entry module 3051 to receive the storage attributes entered by the user in the attribute dialog box. Among them, the so-called storage attributes include storage names, storage formats (for example, gif, jpg, tif, png, bmp, etc.).

The instant save unit 305 uses its format conversion module 3052 to determine whether the original format of the acquired IM screenshot is consistent with the storage format entered by the user: If not, the format conversion module 3052 formats the IM screenshot; if so, the instant save unit 305 The above IM screenshot is saved by its storage module 3053.

Step 2009: Restore the above IM chat window to the user interface.

After the user completes the interception of the picture, the screenshot unit 103 notifies the dialog control unit 102 that the truncation is completed. The dialog control unit 102 generates and transmits a display instruction to the UI unit 101 based on the saved attribute information and feature information. The UI unit 101 receives the display instruction and executes, thereby restoring the above IM chat window to the user interface.

Step 2010: Paste the captured picture in the IM chat window.

After the IM chat window is restored, the screenshot unit 103 further transmits the captured image to the UI unit 101, and the UI unit 101 further acquires the image captured by the screenshot unit 103 and pastes it into the current chat window.

Of course, in the actual application, the editing operation and saving operation of the above IM screenshot can also be performed. In step 2010, the captured picture is first pasted into the IM chat window, and the captured picture is edited and saved in the chat window.

It should be noted that the typical application of the present invention is not limited to screenshots in instant messaging software, and the methods set forth in the present invention may be applied in other similar scenarios.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. Within the scope.
