Embodiment Construction

[0028] In the present invention, the screenshot operation is conveniently realized through the structure of the touch screen. During the screenshot operation, the multi-touch operation information can be collected as the positioning information of the area selected when the screenshot is taken.

[0029] ginseng figure 1 As shown, the method described in the present invention includes the following steps:

[0030] Step S110, in the screenshot state, collect the touch point position obtained through the touch screen;

[0031] Step S120, for the two touch points, use these two touch points as the diagonal endpoints of the screenshot rectangle range to determine the screenshot range;

[0032] Or, for three or more touch points, select the two touch points with the largest distance as the endpoints of the diagonal of the screenshot rectangle;

[0033] Or, for three or more touch points, select the positions of all touch points, and then construct a minimum rectangular range incl...

Abstract

The invention provides a method for realizing screen-capture by multipoint touching, which belongs to the technical field of computer and software. The method includes collecting touch point positions acquired by a touch screen in a screen-capture state; for two touch points, adopting the two touch points as diagonal endpoints of a screen-capture rectangular range to determine a screen-capture range, and for three or more touch points, selecting two touch points with maximum distance therebetween as diagonal endpoints of the screen-capture rectangular range or constructing a minimum rectangular range including all the touch points to serve as the collected screen-capture range; and performing screen-capture operation on corresponding window contents aimed to the screen-capture range acquired in the above step. The invention can conveniently realize screen-capture operation by multipoint touching.

Description

technical field [0001] The invention belongs to the field of computer and software technology. technical background [0002] At present, terminal devices equipped with touch screens are widely used, for example, mobile phones, tablet computers, notebook computers, desktop computers, or personal digital assistants with touch screens, and so on. [0003] On the other hand, in the process of people using the terminal device, by way of screenshot, after locating the starting point and end point of the screenshot, the screenshot processing can be performed; or, the screenshot operation can be performed by locating the boundary of the screenshot area. [0004] In the current situation where screenshots are used, most of the screenshot operations are guided by the mouse to move the cursor to form a screenshot area. [0005] When using a touch screen to perform a screenshot operation, the position movement operation of the touch screen is often misjudged as the user wants to move t...
