Hi Marty,
would it help if the transparent parts where just a little non-transparent?
hardly noticeble
You would set all 0 to 1 in alphaData, the rest is unchanged.
-------------------------------------------
on mouseUp
put the alphaData of image 1 into tAlpha
put numToByte(0) into tNull
put numToByte(1) into tOne
repeat for each byte anAlpha in tAlpha
if anAlpha = tNull then
put tOne after tCollect
else
put anAlpha after tCollect
end if
end repeat
set the alphaData of image 1 to tCollect
end mouseUp
---------------------------------------------
this is fairly fast, works also in 7.x.x
Once you change 0 to 1 in alphaData the translucent parts of the png receive
mouseClicks etc. You must be aware of that.
Kind regards
Bernd
