Abstract

The embodiment of the invention relates to a method and device for realizing effect of a trotting horse lamp. The method comprises the following steps: acquiring a trotting horse lamp image; image initial coordinate information of a first area image in the trotting horse lamp image is obtained through calculation based on the trotting horse lamp image and a display area of a target display screen, and the image initial coordinate information is basis information of a first display image obtained by rendering the first area image through a graphics processor; obtaining an initial model transformation matrix of the first area image, and processing the initial model transformation matrix based on the displacement step length under a displacement step length setting operation instruction to obtain a target model transformation matrix; and obtaining a second display image obtained by rendering a second area image in the trotting horse lamp image by the graphics processor according to the image initial coordinate information and the target model transformation matrix, wherein the second display image translates the displacement step length relative to the first display image. According to the embodiment of the invention, drawing is executed in the graphics processor, so that the drawing efficiency is improved.

Description

technical field [0001] The invention relates to the field of LED display screen display, in particular to a method for realizing the effect of a revolving lantern and a device for realizing the effect of a revolving lantern. Background technique [0002] With the rapid development of the LED display market, there are more and more applications in the LED display that need to scroll and display text or pictures in a circular manner, that is, to achieve the effect of a carousel. [0003] At present, the revolving lantern effect is realized on the LED display by first displaying text or picture content on a component, then embedding the component on the LED display, and then moving the component to realize the revolving lantern effect. However, there are certain defects in realizing the revolving lantern effect in this way, because the process of drawing is realized by the CPU, but because there are many pictures to be drawn, the efficiency of drawing is low. Contents of the ...
