[RESOLVED] Rotated image appears somewhat blurry.

[Traps]

Is there anyway to get around this? Basically I am trying to rotate an arrow that I am using in place of the treeview's plus/minus expander. When I rotate it -45 degrees, the arrow loses its border, or appears blurry.

Here is my code for rotating the image:

        private Image RotateImage(Image myImage, int myAngle)
        {
            Bitmap b = new Bitmap(myImage.Width, myImage.Height);

            Graphics g = Graphics.FromImage(b);

            g.TranslateTransform((float)b.Width / 2, (float)b.Height / 2);
            g.RotateTransform(myAngle);
            g.TranslateTransform(-(float)b.Width / 2, -(float)b.Height / 2);
            g.DrawImage(myImage,new Point(0,0));
            g.Dispose();

            return myBitMap;
        }
