[Gimp-user] Image diffenernt after saving

[Silt <forums gimpusers com>]

I forgot to say that, but it is not really tansparent, Privot takes the bottom
right (or left, I'm not sure) pixel and makes all of this color tansparent. So
in GIMP 2 it is white, and in Privot tansparent, with the bug as shown in the
image. But yes I will try that with the eraser tool, thanks for your answer.
