      Try libjpeg. It's fairly low level so you should be able to do pretty much anything you need to do with jpegs. Lib JPEG[^]


      If you can keep you head when all about you Are losing theirs and blaming it on you; If you can dream - and not make dreams your master; If you can think - and not make thoughts you aim; Yours is the Earth and everything that's in it. Rudyard Kipling

        I would avoid using 3rd party software as much as possible. How difficult it is to write a function to convert a jpeg file to a thumbnail file? I also have a need to convert other image formats to a thumbnail format. Elizabeth

          It aint worth writing ur own code to do it, plus the jpeg decomp libs are free. Otherwise check out CxImage in codeproject. Jesus! i am still alive.

            It sounds very helpful. Can you tell me where I find the jpeg library file? I hope there is not much work when I deploy my application to a client machine. Elizabeth
