Problems solved by technology

This method needs to call historical data and takes up a lot of memory. According to the two endpoint values ​​and the size of the compressed image, the ratio of the image to be compressed is calculated and compressed by the ratio, which greatly affects the running and operation of the program. The method is single and easy to compress. Restricted, and the program is complex and the amount of operation is large

Abstract

The invention discloses a picture compression method and system, a terminal and a storage medium. The picture compression method comprises the steps: receiving a picture compression triggering request, wherein the picture compression request comprises a compression type, the size of a to-be-compressed picture and / or an application type; selecting a corresponding compression mode for compression according to the compression type, wherein the compression type comprises one or more of sampling rate compression and quality compression, and if the sampling rate compression and the quality compression are both set, the sampling rate compression is firstly carried out and then the quality compression is carried out. According to the picture compression method and system, the terminal and the readable storage medium, sampling rate compression and quality compression or combination of sampling rate compression and quality compression can be carried out according to instructions or requirements, the limitation of a single compression mode is avoided, the advantages of the two modes are brought into full play, different compression is carried out according to different requirements, and thecompression flexibility is improved.

Description

technical field [0001] The present invention relates to picture processing technology, in particular to a picture compression method, system, terminal and storage medium. Background technique [0002] In the existing technology, Luban claims to be the closest open source library to WeChat compression, with 60% compression quality. Compressor allows developers to customize the pixels and quality, which requires developers to constantly try parameters to find the most suitable equalization effect, which brings a lot of time cost to developers for testing image quality. [0003] Another example is a picture compression method disclosed in CN109672888, which needs to obtain the historical compression data of each picture compression tool, obtain the ratio of compressed picture adaptation and the picture compression tool according to the historical compressed data, the size of the compressed picture, and the application type, and call the appropriate The interface of the provide...
