I just tried this with a circular PNG as the original image
and the end result had quite a fat white border all around it
which would seem to indicate that when the SNAPSHOT is imported
into the "HOLDER" image it shrinks a bit . . .

on mouseUp
  create image "HOLDER"
  set the transparent of img "Circle.png" to true
  put top of group "gZ" into TOPP
  put bottom of group "gZ"  into BUM
  put left of group "gZ"  into LEFTT
  put right of group "gZ"  into RITE
   put LEFTT & "," & TOPP & "," & RITE & "," & BUM into fld "fRECT"
  put fld "fRECT" into FRECT
  put the windowID of this stack into WINDY
  set the fileType to empty
  set the width of img "HOLDER" to the width of img "Circle.png"
  set the height of img "HOLDER" to the height of img "Circle.png"
     export snapshot from rect FRECT of window WINDY to img "HOLDER" as PNG
     set the width of img "HOLDER" to the width of img "Circle.png"
  set the height of img "HOLDER" to the height of img "Circle.png"
     set the alphaData of img "HOLDER" to the alphaData of img "Circle.png"
     export img "HOLDER" to file "ROUND.png" as PNG
     delete image "HOLDER"
end mouseUp

----------------------------
so the alphaData of the original PNG does not 'fit' the new image
'snugly' . . .

"Throw me a frikking bone!"
