    Hai! I am using the following sorce code to display JPEG images in my Win CE application developed using eVC++ for a pocket PC device. http://www.pocketpcdn.com/articles/jpeglib.html Actually i get a bitmap handle by using the above source code, i display this bitmap handle on my picture control. Actually i am displaying the image with its original size, but i am not able to see the whole image as the size of screen of my WIN CE device is very small, so i want to display compressed image or display the image after reducing its size? Is there any function to do it? Thanks!

      My DLL [^] performs such task. You may use, as well, the GDI+ for the purpose. :)

        Also StretchBlt[^], which has the advantage of definitely being available of any WInCE build, but the disadvantage of using a lousy resampling algorithm.
