In the process of storage, the quality of the picture can be selected according to the format of the stored picture, such as saving it as jpg format;

If saved as png, there are two kinds: png8 and png24. The difference is:

Each "png8" picture can only display 256 colors at most, so the "png8" format is more suitable for those pictures with a single color, such as solid colors, logo, icons and so on. Because the number of colors is small, the size of the picture will be smaller;

Each "png24" image can display far more colors than "png8", and the maximum number of colors that can be displayed is16 million; Therefore, the picture displayed by "png24" will be richer in color, better in definition and higher in quality, and of course, the size of the picture will increase accordingly, so the picture of "png24" is more suitable for pictures with rich colors like photos;
