       SippCopy [flags] inputHandle outputHandle
              This  command  copies a single image from one image
              store to another.   If the image store  is  capable
              of  storing  multiple  images,  only  one  image is
              copied.  The input and  output  images  can't  have
              conflicting scanning directions (i.e. can't copy an
              RLE file to a PBMPlus file).  Pixmaps can  be  used
              to  buffer  copies  between  image stores with con-
              flicting scanning directions.

              When copying  between  image  stores  that  support
              image  comments  (RLE  files and pixmaps), comments
              from the input image are  merged  into  the  output
              image  comments. Comments in the output image over-
              ride a comment by the  same  name  from  the  input
              image.   In RLE files, all comments are reset after
              a writing the image has  completed.   New  comments
              can  then  be added and another image copied to the
              RLE file.  With pixmaps,  comments  are  not  reset
              after  storing  an image in it.  If a single pixmap
              instance is reused, the comments should probably be
              cleared  with  SippCommentDelete  before adding new
              comments and storing a new image.

              The following optional flags may be specified:

                 o -clear - Causes images  copied  to  the  a  Tk
                 photo  image  to  be  cleared before copying the
                 image.   This is the default.

                 o -noclear - Causes images copied to  the  a  Tk
                 photo image to not be cleared before copying the
                 image.  The contents of the previously  rendered
                 image  will remain until a scanline is overwrit-
                 ten by the new image.  This is most  useful  for
                 overwriting  a  LINE  rendered  image with fully
                 rendered image.  Only one of -clear or  -noclear
                 may be specified.
