       SippCopy inputHandle outputHandle
              This  command  copies a single image from one Image
              Storage Object (ISO) to another.  The  input  image
              may  be  from  an  RLE  file,  a  PBMPlus file or a
              pixmap. The output object can be any of there, plus
              the  Tk  photo  widget.   If  the ISO 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  ISOs  with  conflicting   scanning
              directions.

              When  copying  between ISOs that support image com-
              ments (RLE files and pixmaps),  comments  from  the
              input  image  are merged into the output image com-
              ments. Comments in the output image override a com-
              ment 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 SippPixMapDelCom before  adding  new  comments
              and storing a new image.

              The following optional flags may be specified:

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

                 o  -noclear  - Causes images copied to the photo
                 widget 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.
