Embodiment Construction

[0022] The invention provides a method and device for realizing an image container control with a convex mirror effect on a large-screen mobile device. The image container control with convex mirror effect refers to an interface image container that can create the effect of placing a convex mirror in the center of the display window. The container contains a series of image sub-controls. When you slide your finger, you can select the image sub-controls. Image The sub-control gradually increases as the direction of the finger slides toward the center of the screen, and gradually shrinks when it moves away from the center of the screen. The present invention aims at providing a lightweight resource consumption implementation method for an image container control with a convex mirror effect under a limited usage scenario of CPU and memory resources.

[0023] For the runtime structure of the image container control with convex mirror effect, see figure 2 . The image container c...

Abstract

The invention provides a method and a device for realizing an image container control with the effect of a convex lens. The method comprises the following steps of: collecting the offset delta x of x-coordinate generated by moving figures on a touch screen at intervals per unit time using the top left corner of a main window as the origin of coordinate of the main window; calculating the X coordinate Xw(i) of the origin of coordinate of a display window according to the offset of the coordinate x generated by moving figures at intervals per unit time and calculating the zoom coefficient according to the X coordinate XC in the centre point of the display window and the X coordinate X(i) in the centre point of the subcontrol; obtaining the width W(i) of a new image and the height H(i) of a new image according to the zoom coefficient; calculating coordinate X at the top left corner of the new image according to the X coordinate X(i) in the centre point of the subcontrol, the width W(i) of the new image and the X coordinate Xw(i) of the origin of coordinate of the display window; calculating the coordinate Y at the top left corner of the new image according to the Y coordinate H in the centre point of the subcontrol and the height H(i) of the new image; and drawing the image according to the parameters. The invention realizes the image container control with the effect of the convex lens in a way of light-weight resource consumption in case of limited CPU and memory resources.

Description

technical field [0001] The invention relates to the field of mobile device application development of the mobile Internet, in particular to a method and device for realizing an image container control with a convex mirror effect. Background technique [0002] With the rise of the mobile Internet, mobile devices with large screens facing the mobile Internet are more and more widely used. The characteristics of large-screen mobile devices are: the screen is generally larger than 4 inches and smaller than 6 inches, the CPU has relatively strong computing power, the user interface is mainly oriented to finger operations, and the operation effect of finger sliding on the touch screen is the main factor affecting user experience. [0003] Aiming at the commonly used functions on large-screen mobile devices: contact selection, playing song selection, browsing pictures and other scenarios, it provides an image container control with a convex mirror effect in finger operation mode. ...
