If you compiled nano-X with LINK_APP_INTO_SERVER = Y you may use 
GrNewPixmap(GR_SIZE width, GR_SIZE height, void *pixels) which allocates 
some space into pixels (see srvfunc.c), then GrCopyArea to copy your 
window into the id returned by GrNewPixmap, and save directly pixels[] 
in a file. Don't forget to free(pixels) :)
AFAIK GrNewPixmap ignores void *pixels if LINK_APP_INTO_SERVER = N.
Some better solution for this?

Carlo
