path=lnamemk(5,'sashelp.imagapp.gkids','format=cat');
rc=imgop(task-id,'SELECT',1);
rc=imgop(task-id,'READ_PASTE',1,1,path);

if (zoom eq 1) then
   do;
      rc=imgop(task-id,'SELECT',2);
      rc=imgop(task-id,'COPY',1,2);
      rc=imgop(task-id,'SCALE',width,height);
      rc=imgop(task-id,'PASTE',1,1);

      if (unzoom=1) then
         do;
            rc=imgop(task-id,'UNPASTE');
         end;
