I'm hoping to write some code to save the contents of a window

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

$ 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.

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.
