Hello...

i want to draw on my form PNG file with alpha-blended transparency.
so i use this code:

Graphics canvas = e.Graphics;

Image Image = Image.FromFile(@".\Dragon.png");

canvas.DrawImage(Image, 0, 0, Image.Size.Width, Image.Size.Height);



the problem is, what alpha-blending do not work, and i can't find any useful
examples...
