This should be easy... call me dumb ...
I've got a TImage control with transparent set to true.
Calling Picture.SaveTofile('test.png') saves the image with a white
background.

What am I missing?

Transparent property of TImage: TImage.Transparent := True applies
that the image is visible when shared, but not when saved.

Try using BGRA Bitmap.

Hi,

Yes it works with a TBGRABitmap.
