#  This reduces or "shrinks" a picture by an interger factor (non-floating
#  point values only).  This is very useful when rendering large images for
#  film transfer.  ie 2k, 4k, 8k etc.  The display program can shrink an image
#  down to display on the screen, but the time necessary is prohibitively long
#  because most people don't have enough RAM to do this without swapping to
#  disk.  So a 4k image displayed smaller could take 8 minutes or more, whereas
#  with this reduce method, it would only take 1 or two minutes to create a
#  new file, and show this file with display or showpic (my favorite).
#  test.1 is the original
#  test.2 is the file created for "easy" viewing
#  4x4 is the reduction ratio in x and y
#  "-v" is verbose

reduce test.1 test.2 4 4 -v
