Rgb888 and rgb565 convert each other

Background: In our computer, images are displayed in rgb888 format. Each pixel of the 24-Bit Bitmap stores 32-bit data, that is, rgb888 + Alpha, and Alpha is a translucent padding Byte ...... However, for a true color image, it is difficult for the naked eye to distinguish between 16 bits. Therefore, in some cases, rgb888 can be converted to rgb565 for storage, which reduces the storage capacity, reduces the data size. When the backend is displayed, rgb565 is converted to rgb888 again to achieve
