    Post Image reading and writing

    Dear all!

    I have intensity values of an image in a 2D matrix array. I want to save this information in the form of an image (.jpeg,bmp,tiff etc). Now each of these image formats have a specific file structure.
    Can you people guide me, from where I can get the library or function that takes the intensity information in an array and writes them into image file? and similarly i also want the reverse of this, i.e. reads the intensity values from image file and writes them into an array.

    So, you have an unspecified form of intensity for which you want a magic function to dump into various images format?

    Good luck finding such a beast.

    On the other hand, if you are willing to do some work yourself, you could always throw "C++ image file libraries" at your favorite search engine and come back to ask questions if you have trouble with the logic of using such libraries.

    I'd say Qt. QImage and its related set of classes will probably help you.

    Outside of your DOS world, your header file is meaningless.
