How to take a JPEG out of IplImage* and not saving it to hard drive put saved dat into char*?

JPEG is a complex format. You can use the IJG jpeg library as a base to work with. However, be warned, it is a mess in itself and has a slight learning curve.It is open source, and you'll typically need to configure its build according to your compiler using a provided makefile (which may not be found with the library code itself).

However, IJG is set up to work with file streams, and special measures are needed to set the library up to work in memory rather than a file. If you email me tomorrow I will send you my source code. It's not for the faint of heart and probably won't learn you anything.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
