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
This idea seems very good indeed: the fact that the areas set at 1 in alphaData will recieve mouseClicks is no worse than my suggestion about layering with an opaque graphic, but those transparent areas will still appear transparent to the end-user, while with my suggestion
they would have ended up as white. Richmond. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
