You're taking raw X image data and stuffing it into a file, apparently
hoping (in vain) that it somehow matches Sun's rasterfile(5) format.
Well, apparently it doesn't.  You haven't provided any real clue as to
what the problem is (e.g. you don't say anything about whether xviewsun
gives an error message or just displays a skewed image, or complete
garbage); how do you seriously expect anyone to help you?  On a random
guess that you've done everything else right, please note that in the
very first paragraph of rasterfile(5) is says that scanlines must be
padded to 16 bits.  There's no guarantee that your X image conforms to
this (in fact it's almost certain that it doesn't).
