Hello,

MakeTransparent works with a color to compute transparency.

Is it possible Bitmap use alpha layer of a 32 bits bitmap ?

I try using a PNG image for a control BackgroundImage but it seems to does not
work. I could not see the Control's BackColor throught the Bitmap's alphalayer.

Thanks for your lights,
