我有一個(gè)關(guān)于螺旋繪圖的問題。以下來源來自鏈接。http://www.java2s.com/Code/CSharp/2D-Graphics/Spiral.htm螺旋為您提供空間。我希望螺旋填滿屏幕。protected override void OnPaint(PaintEventArgs pea){  DoPage(pea.Graphics, ForeColor, ClientSize.Width,ClientSize.Height);}protected void DoPage(Graphics grfx, Color clr, int cx, int cy){    const int iNumRevs = 3;    int iNumPoints = iNumRevs * 2 * (cx + cy);    PointF[] aptf = new PointF[iNumPoints];    float fAngle, fScale;    for (int i = 0; i < iNumPoints; i++)    {    fAngle = (float)(i * 2 * Math.PI / (iNumPoints / iNumRevs));    fScale = 1 - (float)i / iNumPoints;    aptf[i].X = (float)(cx / 2 * (1 + fScale * Math.Cos(fAngle)));    aptf[i].Y = (float)(cy / 2 * (1 + fScale * Math.Sin(fAngle)));    }    grfx.DrawLines(new Pen(clr), aptf);}圖片
