求助求助，c#编程如何设Texture透明

newlju

翻看了以前的前子也没能解决。代码：

private Device device = null;
private Texture spriteTexture = null;
private Sprite sprite = null;
private Rectangle textureSize = Rectangle.Empty;

public void InitializeGraphics()
{

  PresentParameters presentParams = new PresentParameters();
  presentParams.SwapEffect = SwapEffect.Discard;
  presentParams.Windowed = true;
  presentParams.BackBufferCount = 1;

  device = new Device(0, DeviceType.Hardware, this,   CreateFlags.SoftwareVertexProcessing, presentParams);

  device.SetRenderState(RenderStates.AlphaTestEnable,true);
  //device.SetRenderState(RenderStates.AlphaBlendEnable,true);


  spriteTexture = TextureLoader.FromFile(device, @"directx.bmp",32,32,0,Usage.None,Format.Unknown,Pool.Default,Filter.None,Filter.None,0x000000);                       
                       
  textureSize = new Rectangle(0, 0, 32, 32);
               
  sprite = new Sprite(device);
}

应该是TextureLoader.FromFile函数的最后一个参数，是设置Alpha的！
