Transparency

[Richmond Mathewson]

This works:

on mouseUp
  set the transparent of img "Yellow.png" to true
  put top of group "gX" into TOPP
  put bottom of group "gX"  into BUM
  put left of group "gX"  into LEFTT
  put right of group "gX"  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 group "gX"
  set the height of img "HOLDER" to the height of group "gX"
     export snapshot from rect FRECT of window WINDY to img "HOLDER" as PNG
      set the width of img "HOLDER" to the width of img "Yellow.png"
  set the height of img "HOLDER" to the height of img "Yellow.png"
     set the alphaData of img "HOLDER" to the alphaData of img "Yellow.png"
     export img "HOLDER" to file "GOTTIT.png" as PNG
end mouseUp


Obviously the reason I was getting 'Tiger Stripes' was that the image
"HOLDER" was not the same as the group "gX".

HOWEVER; the result is a PNG of the odd-shape with a 'cute' little,
white drop-shadow: I wonder why.

sincerely, Richmond Mathewson.
