[DelphiX] Zeichnen mit Transparenz

[Flogo]

Hi ijcro,
could you give a quick explanation on how to get the alphachannel in the DIB? I tried it with Photoshop (new file -> background = transparent -> a few lines with the brush -> save as -> dib) but it just didnt save the alphachannel.
Well maybe it did, but there was no transparence while drawing on the DXDraw surface.
Is it possible to use the Sprite/ImageSprite classes just as before by changing the Image from a "foo.bmp" to a "foo.dib" or do you have to change something else?

I just tried to load the image with this TDIB component and called
  DXDraw.Surface.LoadFromDIB(DIB.AlphaChannel); I saw the Alphachannel, so it must have been saved. But there is still no sign of the Alphachannel when I draw the picture as a Sprite..
