 function saveimage (filename, img, img_form, map)
 
-# Save a matrix to disk in image format.
-#
-# saveimage (filename, x) saves matrix x to file filename in octave's
-# image format.  The current colormap is saved in the file also.
-#
-# saveimage (filename, x, "img") saves the image in the default format
-# and is the same as saveimage (filename, x).
-#
-# saveimage (filename, x, "ppm") saves the image in ppm format instead
-# of the default octave image format.
-#
-# saveimage (filename, x, "ps") saves the image in PostScript format
-# instead of the default octave image format. (Note: images saved in
-# PostScript format can not be read back into octave with loadimage.)
-#
-# saveimage (filename, x, format, map) saves the image along with the
-# specified colormap in the specified format.
-#
-# Note: If the colormap contains only two entries and these entries
-# are black and white, the bitmap ppm and PostScript formats are used.
-# If the image is a gray scale image (the entries within each row of
-# the colormap are equal) the gray scale ppm and PostScript image
-# formats are used, otherwise the full color formats are used.
