 > ⚠️ Before obtaining an array of ARGB pixels for the image, **it is recommended** (but not necessary if your image is already small in size or you just don't mind about execution time) to adjust its dimensions to 128x128 (by `resize` function from `image` crate, for example). The reason is described [**here**](https://github.com/material-foundation/material-color-utilities/blob/main/extract_colors.md).
