我正在尝试编写一个显示带有PictureBox的Wii遥控器旋转的程序。当Wii遥控器在X轴上旋转时,Wii遥控器的图像也会旋转。旋转值已显示在文本框中,如下所示:0.109243284720305
或-0.132414335
。
如何使用这些值旋转显示的图像?

创建继承自PictureBox的自定义控件,并覆盖OnPaint虚拟方法以根据需要绘制wiimote位图:
public partial class WiiMoteControl: PictureBox {
public Bitmap wiimote;
private float _angle;
public float Angle {
get { return _angle; }
set { _angle = value; Invalidate( ); }
}
protected override void OnPaint( PaintEventArgs pe ) {
base.OnPaint( pe );
pe.Graphics.ResetTransform( );
pe.Graphics.TranslateTransform( Size.Width / 2, Size.Height / 2 );
pe.Graphics.RotateTransform( Angle );
pe.Graphics.TranslateTransform( -Size.Width / 2, -Size.Height / 2 );
if (wiimote != null) {
pe.Graphics.DrawImage( wiimote, 0, 0, Size.Width, Size.Height );
}
}
}
