Abstract

The invention discloses a method for rotating a picture through the coordinate axis proportion and the difference. The method comprises the steps of firstly, performing a first judgment action through a touch algorithm to judge whether the picture has two touch points; if two touch points are touched, performing a collecting action to collect X coordinate values and Y coordinate values of the two touch points in the Y coordinate axis and the X coordinate axis, performing a second judgment, and determining the touch point with the smaller Y coordinate value as an axis point and the touch point with the larger Y coordinate value as a rotating point according to sizes of the Y coordinate values respectively; and after the rotating point generates displacement, performing a third judgment, deciding whether the picture is rotated to the left or right through judging of the absolute value of the variation of the ratio (Y / X value) of the Y coordinate value to the X coordinate value of the rotating point or through judging whether the two touch points are located in the X coordinate axis or the Y coordinate axis. Through the method, calculation can be simplified, resources required by calculation can be reduced, and the efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of screen rotation, in particular to a method for judging a rotated screen by using coordinate axis ratios and differences. Background technique [0002] Nowadays, smart phones are constantly being introduced, providing more functions and services to meet our various needs, coupled with more humanized and smarter functions, so that the overall demand continues to grow, and there is an urgent need for more and more Good problem solving. [0003] Since most displays are rectangular, many functions such as electronic maps, satellite positioning navigation and games, etc. need to rotate the screen. The known method of determining the rotation of a screen by touch is to use the change of the relative angle (θ) of two points to determine the rotation of the screen, such as figure 1 (well-known technology). However, the microprocessor in the touch control system needs more calculation processing to calculate the...
