Ok, I've adapted a script from Alejandor Tejada's "Polygon Graphic
Transformations" into a function which has the functionality of
RevRotatePoly.




function rotateGraphic gName,rAngle
  
  put "graphic "&quote&gName&quote into lvselectedgraphic
  if existence(lvselectedgraphic) is false then exit rotateGraphic
  
  if the checkLocation of lvselectedgraphic is empty or checkLocation <> the
loc of lvselectedgraphic
  then  set the exactPoints of lvselectedgraphic to empty
  put "1,1 cosangle"&return&"1,2 sinangle"&return&"1,3 0"&return&"2,1
sinangle"&return&"2,2 cosangle"&return&"2,3 0"&return&"3,1 0"&return&"3,2
0"&return&"3,3 1" into fldsource
  put "1,1 1"&return&"1,2 0"&return&"1,3 movX"&return&"2,1 0"&return&"2,2
1"&return&"2,3 movY"&return&"3,1 0"&return&"3,2 0"&return&"3,3 1" into
fldmove0
  put "Graphic" into origin
 
  put (the left of lvselectedgraphic + the width of
lvselectedgraphic/2),(the top of lvselectedgraphic + the height of
lvselectedgraphic/2) into mzbx
 
  put -(item 1 of mzbx),-(item 2 of mzbx) into mzbx2
  
  put fldmove0 into fldmove1
  put fldmove0 into fldmove2
  
  put cos(rAngle * pi / 180) into word 2 of line 1 of fldsource
  put - sin(rAngle * pi / 180) into word 2 of line 2 of fldsource
  put sin(rAngle * pi / 180) into word 2 of line 4 of fldsource
  put cos(rAngle * pi / 180) into word 2 of line 5 of fldsource
  
  put item 1 of mzbx into word 2 of line 3 of fldmove1
  put item 2 of mzbx into word 2 of line 6 of fldmove1
  put item 1 of mzbx2 into word 2 of line 3 of fldmove2
  put item 2 of mzbx2 into word 2 of line 6 of fldmove2
  
  put fldmove1 into qwe
  --   put qwe
  --   exit mouseup
  
  split qwe by return and space -- qwe is converted in an array
  put fldsource into qwa
  --  put qwa
  --  exit mouseup
  
  split qwa by return and space
  put matrixMultiply(qwe,qwa) into qws
  put fldmove2 into qwe
  --  put qwe
  --  exit mouseup
  
  split qwe by return and space
  put matrixMultiply(qws,qwe) into qwa
  combine qwa using comma
  -- put qwa
  put "1,1" & space & item 1 of qwa & return into fldsource
  put "1,2" & space & item 2 of qwa & return after fldsource
  put "1,3" & space & item 3 of qwa & return after fldsource
  put "2,1" & space & item 4 of qwa & return after fldsource
  put "2,2" & space & item 5 of qwa & return after fldsource
  put "2,3" & space & item 6 of qwa & return after fldsource
  put "3,1" & space & item 7 of qwa & return after fldsource
  put "3,2" & space & item 8 of qwa & return after fldsource
  put "3,3" & space & item 9 of qwa after fldsource
  
  put "1,1 0"&return&"1,2 0"&return&"1,3 1"&return&"2,1 0"&return&"2,2
0"&return&"2,3 1"&return&"3,1 0"&return&"3,2 0"&return&"3,3 1" into flddata
  if the exactPoints of lvselectedgraphic is empty then put the points of
lvselectedgraphic into fldpointsofgraphic else put the exactPoints of
lvselectedgraphic into fldpointsofgraphic
  put fldsource into qwe
  split qwe by return and space -- qwe is converted in an array
  
  repeat the number of lines of fldpointsofgraphic
    put item 1 of line 1 of fldpointsofgraphic into word 2 of line 3 of
flddata
    put item 2 of line 1 of fldpointsofgraphic into word 2 of line 6 of
flddata
    delete line 1 of fldpointsofgraphic
    put flddata into qwa
    split qwa by return and space
    put matrixMultiply(qwe,qwa) into qws
    combine qws using comma
    -- put qws
    put item 3 of qws,item 6 of qws & return after fldexactpointsofgraphic
    put round(item 3 of qws) & comma& round(item 6 of qws) & return after
fldnewpointsofgraphic
  end repeat
  
  set the points of lvselectedgraphic to fldnewpointsofgraphic
  set the exactPoints of lvselectedgraphic to fldexactpointsofgraphic
  set the checkLocation of lvselectedgraphic to the loc of lvselectedgraphic
  choose browse tool
end rotateGraphic
