Do you mean alphaData? If I understand what you're asking, it sounds like
you want to set the alphaData of one image to the imageData of another. The
only way I know how to do this via the math.
set alphaData of img 2 to tmImageToAlpha(imageData of img 1)
function tmImageToAlpha pData
put 2 into C
repeat (length(pData)/4)
put numToChar(255 - charToNum(char C of pData)) after tAlpha
add 4 to C
end repeat
return tAlpha
end tmImageToAlpha
