    I'm hoping to write some code to save the contents of a window
    clicked on by the mouse to a file and my plan was to get its image,
    save the pixels then reload them into an image created by
    XCreateImage.

    Why don't use xwd to save the image of a window?

    $ man 1 xwd

    reload them into an image created by XCreateImage.

    $ man 1 convert (from the ImageMagick package)

    I'd look at the sources for xwd (part of the X11 distribution)
    to see how they handled the colormaps and/or direct color.

    Why don't use xwd to save the image of a window?

    Because I'm saving more than just the image of a window and I don't like
    using system() or popen() to fork a utility that may or may not be available.
