Page switching method and device
A technology of page switching and tabbing, which is applied in the input/output process of instruments, electrical digital data processing, and data processing, etc., can solve the problems of lack of association between pages, lack of buffering before and after page switching, and inability to control page switching. Switching speed, enhanced connection, fast response effect

[0028] like figure 1 As shown, it is a schematic flow chart of a page switching method according to Embodiment 1 of the present invention. In this embodiment, the page switching method includes:
[0029] Step S101, acquiring bitmaps of adjacent tab pages, and generating composite bitmaps according to the bitmaps of adjacent tab pages;
[0030] When obtaining the bitmap of the adjacent tab page, in general, draw the corresponding bitmap according to the page content of the adjacent tab page.
[0031] Specifically, different methods may be adopted according to browsers with different kernels. For example, for browsers with the chrome kernel, a memory bitmap is created in the rendering (render) process as a drawing canvas (an object drawn by the user in the chrome code), and the render process is redrawn to obtain adjacent tab pages The page bitmap of any tab page. Under the IE kernel, you can use the Draw function of the IviewObject interface to draw the page content into the...

[0045] In order to facilitate the above figure 1 Steps S101 and S103 in, which may further include:
[0046] figure 1 Step S101 shown in may further include: splicing the bitmaps of adjacent tab pages, the height of the composite bitmap is the same as the height of the bitmaps of the adjacent tab pages, and the width of the composite bitmap is the width of the adjacent tab pages the sum of the widths of the bitmaps;
[0047] The composite bitmap may be called a contour map. If the horizontal size of the browser display window is 1024 pixels, the horizontal size of the composite bitmap of the two tab page bitmaps is 2048 pixels.
[0048] figure 1 Step S103 shown in may further include: controlling the starting point and offset of the displayed composite bitmap according to the distance of the mouse sliding and the width of the browser window.
[0049] By detecting the distance that the mouse slides on the browser window during the mouse sliding process, the display area of ...

[0054] like Figure 5 As shown, it is a schematic flow chart of generating a composite bitmap in Embodiment 3 of the present invention. In order to make full use of resources, it is different from the above-mentioned scheme for generating a contour composite bitmap. Step 101 in the above-mentioned Embodiment 1 may further include:
[0055] Step S1011, obtaining the parts to be displayed in the browser window of adjacent tab pages respectively;
[0056] When generating a synthetic bitmap, only a part of the content of each adjacent tab page needs to be used, and the complete bitmap of each adjacent tab page does not need to be used. At this time, the parts of the adjacent tab pages to be displayed in the browser window can be calculated in real time according to the movement of the mouse during the sliding switch. For example, combining image 3 , if the median line 3 between two adjacent tab pages 1 and 2 is used as the dividing line, it is determined according to the mouse ...
