VB6 Picture如何旋轉到指定角度

StarWU

我查到有個範例可以旋轉90 180 270度，如下。　但我想學任意角度的旋轉方法。有高手可提供範例嗎？
        Dim Img As System.Drawing.Image
        Img = System.Drawing.Image.FromFile("C:\Users\Star\Pictures\Blue hills.jpg")
        Dim TargetImg As New System.Drawing.Bitmap(800, 600)
        Dim g As Graphics = Graphics.FromImage(TargetImg)
        Img.RotateFlip(System.Drawing.RotateFlipType.RotateNoneFlipNone)
        g.DrawImage(Img, New Point(0, 0))
        PictureBox1.Image = TargetImg
