Abstract

Disclosed is a picture loading method, comprising steps that electronic equipment obtains a first picture file, the first picture file comprises a format field and a data field, the format field is used for representing a source format of the first picture file, the data field comprises pixel data of the first picture file; the electronic equipment determines a rendering operation corresponding to the first picture file according to the source format of the first picture file; and the electronic equipment renders the first picture file to a display screen according to the rendering operation corresponding to the first picture file. In this way, the electronic equipment can support input of pictures of different source formats, then the pictures are displayed on the display screen in different rendering modes, storage resources of the pictures can be saved, and the storage size of the pictures is reduced. Therefore, the time for loading the picture resources from the Flash to the memory is shortened, and the user experience is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to a picture loading method and related devices. Background technique [0002] The memory of the processor in an embedded system is usually relatively small, so the memory is generally used as a stack space when the code is running. As for the resource cache related to the display of UI pages such as pictures and fonts, it is usually solved by using an external PSRAM (Pseudostatic random access memory, pseudo-static random access memory). Adding a piece of PSRAM will have a very large impact on the hardware cost of the product, power consumption and battery life. Therefore, the size of PSRAM is generally not configured to ensure that the image resources of all pages are cached. Therefore, when the page is switched, it is necessary to clear the image resources of the previous page and load the resources of the new page. The size of the image resource has a great influence ...
