The following simple demonstration programs are provided to illustrate how
to read and write FITS images and tables using the CFITSIO library. 

     fitscopy - copy a file with optional filtering 
     listhead - list header keywords 
     liststruc - list the structure of a FITS file. 
     modhead - write or modify a header keyword 
     imcopy - copy an image with optional compression/decompression 
     imarith - add, subtract, multiply, or divide 2 images 
     imlist - list pixel values in an image 
     imstat - compute statistics of image pixels 
     tablist - display the contents of a FITS table 
     tabcalc - general table calculator 
     tabmerge - merge rows from one table with another table. 
     cookbook - additional example routines. 

The source code files for these working programs are available from

 http://heasarc.gsfc.nasa.gov/docs/software/fitsio/cexamples.html

These are all written in ANSI C and most of them contain only a few 10s of
lines of executable code.  Since these example programs were designed to run
on any platform, there are no examples of how to display an image in
Windows  Some of these should be helpful, however, in learning how to read
the FITS image into an array, which then could be passed to an image display
routine.
