Intelligent watermark moving method

Abstract

The invention discloses an intelligent watermark moving method. The method comprises the following steps of S1, obtaining the size of a screen, calculating the width and height of the screen, and establishing a coordinate axis; S2, setting the transparency of a watermark picture; S3, obtaining the width and height of the watermark picture, and according to the width and height of the screen and the width and height of the watermark picture, randomly generating the position, in the screen, of any end point on the watermark picture; S4, drawing the watermark picture in the screen according to the obtained position of the end point; S5, randomly setting a time interval of watermark picture display; S6, randomly setting a change value of the obtained end point, and obtaining the position of the end point again; if the position obtained after conversion is not in the screen, obtaining the position of the end point again, until the end point is located in the screen; and S7, repeating the steps S4-S6. Through the method, the watermark picture can randomly move on the screen, so that others are prevented from masking a watermark in a mosaic form, and a good anti-theft effect is achieved.
