Question

I am wondering if there is any good tutorial or a book on loading,creating and editing bitmaps in c++. I need to edit bitmap pixel by pixel but none of the tutorials don’t show how. I want to understand how does bitmap “work” and wikipedia helped a little.

Answer 1

If you want to manipulate bitmaps on the pixel level, then you should start learning Image Processing and then read something about bitmap file formats. It is not a C++ question. C++ is just icing on the cake in such task.

Here you can find some lectures on Image processing:

And here is the description of BMP file format:
http://www.fileformat.info/format/bmp/spec/e27073c25463436f8a64fa789c886d9c/view.htm

You can easily find a lot of sources for other formats as well. Good luck, I have been studying this topic three years at the university… I think you really should use some open source library as David Grayson advised.
