      Depends if you want it free or not. Atalasoft DotImage[^] does lossless JPEG.

        $1000 for an SDK that gives us lossless jpg is not unreasonable, but I'm not the one paying, and the one paying has decreed - find something free. Especially when this is overall an imaging SDK, and my core function is to write imaging code... :-) Christian Graus - Microsoft MVP - C++

            No worries. I had found that SDK with google, but thanks for the suggestion all the same. I'm dreading finding some open source library in C and trying to get it to bridge to managed C++ in a dll. That's not the way to go, IMO. Christian Graus - Microsoft MVP - C++

              The closest to that is PNG24, although the extra overhead with PNG32 is not much normally. I dont think lossless jpg is even possible. xacc.ide-0.1.1.4 - now with LSharp integration and scripting :)

                Shouldn't you then spend your time on things others don't have?

                  It's a different compression, but falls under the jpg banner. Christian Graus - Microsoft MVP - C++

                        There is in fact a lossless compression which is known as lossless jpg. It is NOT a normal jpg at 100%, I know that is still lossy. Thanks for taking the time to answer though. Christian Graus - Microsoft MVP - C++
