Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0056]In order to solve the problem of low rendering efficiency of large-scale images without hardware acceleration, after analyzing the rendering process, it is concluded that the reason for the low rendering efficiency is: when the processor draws the image to the display device, if the image scaling ratio is large, The central processing unit (CPU) samples the image and then draws it to the display device, and the sampling process consumes CPU resources. It can be seen that if the pixels of the image to be rendered are similar to the actual pixel size of the rendering area of ​​the display device, the time required for sampling will be less, and the consu...

Abstract

The invention relates to an image rendering method and device, electronic equipment and a storage medium. The method comprises the steps: obtaining a to-be-processed image; judging whether the currentscaling of the to-be-processed image is less than 100% or not; if the current scaling of the to-be-processed image is not less than 100%, obtaining a to-be-displayed area of the to-be-processed imagein the display window, and rendering the to-be-displayed area; if the current zoom ratio of the to-be-processed image is less than 100%, obtaining a preset zoom ratio corresponding to the current zoom ratio, and obtaining a target image layer consistent with or close to the preset zoom ratio from pre-stored image layers, wherein the pre-stored image layer is an image layer which is obtained by processing the to-be-processed image in advance and contains different preset scaling ratios; rendering the target layer, and taking the rendered target layer as a rendering result of the to-be-displayed area. The method and the device are used for solving the problems of poor image rendering performance and display lag when hardware acceleration is not adopted.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to an image rendering method, device, electronic equipment and storage medium. Background technique [0002] At present, the mainstream image browsing software has different degrees of performance problems when browsing super-large images, mainly in the smoothness of browsing. For example, several existing image browsing software have obvious rendering lag when opening large-size images, and the image zooming experience is poor. [0003] In order to solve the problem of obvious lag in rendering when opening large-size images, image browsing software using hardware acceleration has appeared, that is, graphics processing units (Graphics Processing Unit, GPU) are used to quickly draw images, and hardware acceleration can improve image rendering efficiency. Have a good zoom experience. However, the graphics user interface (Graphics Device Interface, GDI) rendering meth...
