Abstract

The invention relates to the technical field of picture processing, in particular to a picture loading method and device. The picture loading method comprises the steps: judging whether partitioning loading is needed or not when a loading instruction for a target picture is received; when partitioning loading is needed, obtaining a tile layer; determining a maximum amplification level corresponding to the target picture and setting a tile size corresponding to the tile layer; determining the number of tiles according to the maximum amplification level and the tile size; partitioning the tile layer and the target picture into blocks to obtain each tile and each picture block; and calling a partitioning drawing method, drawing the picture blocks on the tiles in a one-to-one correspondence manner, and loading the tiles of the drawn picture blocks to complete loading of the target picture. By applying the picture loading method provided by the invention, the target picture is partitioned and then drawn on the tile; each tile is loaded in a partitioned manner; the loading of the target picture is completed; the memory pressure is relieved; the memory is prevented from rising violently;and the main thread of the loaded picture is prevented from collapsing.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture loading method and device. Background technique [0002] With the rapid development of science and technology, more and more functions of application programs have been developed and widely used in people's daily life. Among them, the functions of most applications are related to pictures, so loading pictures has also become one of the important functions of the applications. For example, when a user transmits a picture through an application program, after the user at the receiving end receives the picture, the picture is a thumbnail, and the user at the receiving end clicks to load the picture to obtain the original picture sent by the user at the sending end; or when the user searches for information, By loading the pictures attached to the material, you can understand the content of the material more intuitively. [0003] The inventor found in t...
