How do I change the transparency of an bitmap by percent in Delphi/FMX?


For a Firemokey project i’m working on a Bitmap, which should make a Bitmap on a TImage Component to get more transparent with the time. In order to do so, i want to use a procedure like the following, but it seems as if there is no way to create a change of the transparency as the following:

procedure changeBitmapTransperency(TransparencyInPercent : Integer);
{Set transparency of the bitmap to (TransparencyInPercent) percent}

So, my question is, if there is a way to do so. Thanks for your time and effort,
