Problems solved by technology

However, for scenes with infrequent screen changes, such as some chess and card games, the screen after redrawing is often the same as before redrawing. If this redrawing method is also used, it will bring unnecessary consumption of CPU resources, etc.

Abstract

The embodiment of the invention discloses a method and a device for improving the graphic drawing efficiency. The method comprises the following steps of obtaining the display attribute of each node on the graph of the current frame; detecting the change condition of the display attribute of each node through comparison with the display attribute of each node at the previous frame; re-drawing the graph according to the display attribute of each node only when the condition that the display attribute of each node changes is detected; and for a first preset number of subsequent frames, directly re-drawing the graph according to the obtained display attribute of each node after the obtaining of the display attribute of each node every time. The graphic drawing mode according to the embodiment has the advantages that the number of re-drawing times can be reduced; and the number of times for detecting whether the display attribute of the node changes or not can be reduced, so that the graphic drawing efficiency is really improved, and unnecessary consumption of CPU (Central Processing Unit) resources and the like can be reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for improving graphics drawing efficiency. Background technique [0002] In order to display a dynamic picture on the terminal device, the drawing program usually redraws the graphics at a certain frequency or frame rate, that is, to erase the old graphics and draw new graphics to ensure that the switching of graphics can be controlled. Real-time display, thus forming a smooth dynamic picture effect. Taking HTML5-based games as an example, the current common method is to redraw the graphics X times per second through the Canvas container to ensure the smoothness of the game screen, where X is usually greater than 30 and less than 60. [0003] In the process of implementing the present invention, the inventors found that the graphics redrawing method in the prior art is suitable for scenes where the picture is constantly changing, such as in action ga...
