推荐答案

如果您的实际意思是:如何在位图文件中存储RGB值?"的答案是

If you actually meant: "how are stored RGB values inside a bitmap file?" the answer is here[^].

一次执行一个像素.请注意，它始终是RGB，但取决于颜色图像的深度，可能会有一个Alpha位，所以它将是ARGB.您可以使用CBitmap.GetPixel()方法或GetDIBits() windows api方法.来获取/解码您下注的数据.

Do it a pixel at a time. Be aware that it''s always RGB, but depenbding on the color depth of the image, there could be an Alpha bit, so it would be ARGB. You can use the CBitmap.GetPixel() method, or GetDIBits() windows api method. When you google thaose methods, you should be able to eeasily find out how to get/decode the data you bet back.
