全部,我想用 XNA 在 Windows Phone 中显示全屏相机(Microsoft.Devices.PhotoCamera),如下面的代码所示,我试图改变 screenpos 和 origin 的值,但是没有用,我的有什么问题代码?谢谢
if (CameraTexture != null)
{
Vector2 origin = new Vector2(CameraTexture.Width / 2, CameraTexture.Height / 2);
Vector2 screenpos = new Vector2(240, 400);
spriteBatch.Draw(CameraTexture, screenpos, null, Microsoft.Xna.Framework.Color.White, (float)Math.PI / 2,
origin, 1.0f, SpriteEffects.None, 0f);
}
