How can I read the bitmap's pixel values with Win32 API?

Question

I have a bitmap of the entire screen. I want to read all pixel values (rgb) of the bitmap.

Here is my code:

   BITMAP bmp = GetScreenBitmap(); // somehow I got the bitmap  

there is BITMAP::bmBits but how can I use it?

Answer 1

With GetDIBits or CreateDIBSection
For example, I had posted a sample with CreateDIBSection in this thread : Scanning of screen pixels works in debug mode but not in release mode
