I am new to Xlib programming and I am having trouble determining the color
of the pixel under the hotspot after a user clicks.  I created an image from
the region of the pixmap where the buttonpress was detected in order to
use XGetPixel.  I am aware that to determine the color I must use the ZPixmap
argument to XGetImage, but I don't understand the value XGetPixel returns.
Can anyone please explain what this value means? 
Am I going about this problem all wrong?  Thank you in advance.
