[paragui-users] transparent fading

[taurus]

Hello PL,

  I`m trying to make transparent cross-fade between 2 pictures.

  the temporary surface was created with PG_Draw::CreateRGBSurface,
  then a picture was blitted on it. After that I need to reveal (in a
  cycle with dynamic transparency, as you see) the
  second picture from transparent to opaque over the first one (I set
  the alpha value for the second picture before blitting it). The
  result I`ve got - the surface was filled with black and the second
  picture just revealed from black to its normal opaque state.

  What`s the trick to work with dynamic transparency in ParaGUI?
  What do I have to do (steps)?

  Thank you!

 
Kind regards,
       taurus
