If you are using Bitmaps on Windows then MSDN gently provides sample code (see Using Bitmaps - Windows applications | Microsoft Docs[^]).
Not much straightfoward, I am afraid.

Solution 2

The best articles aobut images and their manipulation are ImageStone and my personal favorite CxImage. But both are written in C++ but there is real a whole lot of knowledge and work condensed. So I guess that it will save you a lot of time to carefully explore them.

A typical work flow in image processing is to detect and resolve the image format and than read the pixels and transform them into a approbiate format.
