read and write standard image files.

I am currently doing some image applications. The first thing to do is loading the standard image files such as img, gif, bmp, jpg, ect. And I also want save a particular part of my screen to a standard image file. Does there exist the functions to perform the loading and saving of the standard image files? Thank you.

There are many image editing libraries available. Leadtools is one of them …

Please… this is not question for OpenGL advanced room. This is not OpenGL question at all.
