Thank you for your questions. Normally, 4-channel RS images contain the Blue, Green, Red, and Near-Infrared bands. You can use our code to directly read 4-channel images. Please see the defination of function read_raster() in functions.py, and its usage in other ###.py files. If you have any other questions, please feel free to contact me via GitHub or Email.

您好，可以再找您咨询一个问题么？为什么我的图片这么黑呢？我直接把tif的四个通道单通道成了图像，是否还需要额外的步骤呢？

Hello, may I ask you another question? Why is my picture so black? I directly take out the single channel of tif data for imaging, do I need additional steps?
