Embodiment Construction

[0032] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the exemplary embodiments described here.

[0033] Application overview

[0034] As mentioned above, currently, after the terminal obtains the produced dynamic image, it displays it through the canvas. The canvas uses JavaScript to draw 2D images, and the canvas is rendered pixel by pixel, and developers can implement arbitrary drawing through Javascript scripts.

[0035] For example, on the canvas of a rectangular area, each pixel is controlled, and JavaScript is used to draw 2D images, which are rendered pixel by pixel. There are several ways to use the canvas element to draw paths, rectangles, c...

Abstract

The invention discloses a dynamic image processing method, a dynamic image processing device, a terminal application and electronic equipment. The dynamic image processing method is applied to the terminal, and comprises the following steps: splitting an obtained initial dynamic image to obtain metadata of each frame of initial image of the initial dynamic image; in response to an image editing operation for the initial image, rendering the initial image on a canvas based on metadata of the initial image and image rendering information indicated by the image editing operation to obtain a target image of the initial image; and according to the sequence of each frame of initial image in the initial dynamic image, storing a target image corresponding to each frame of initial image, or storing the initial image without image editing operation and the target image corresponding to the initial image with image editing operation. Thus, the user can adjust the dynamic image on the terminal based on the own demand, the image processing speed and quality are improved, and the user convenience is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, relates to a dynamic image processing method, a dynamic image processing device, terminal applications, and electronic equipment. Background technique [0002] A dynamic image refers to an image that produces a certain dynamic effect when a set of specific static images are switched at a specified frequency. For example, a common dynamic image is a GIF (Graphics Interchange Format: Graphics Interchange Format) animation, which achieves an animation effect by switching images of multiple layers according to time. [0003] APNG (Animated Portable Network Graphics: Animated Portable Network Graphics) is a bitmap animation extension of PNG, which can realize the dynamic picture effect in png format. Compared with GIF animation, APNG is better in animation fluency. [0004] Currently, the dynamic image needs to be displayed on the terminal through a canvas (...
