   my images have blur why is that
  hi guys i am loading my images as texture on a surface using textureloader.fromfile(device,filename) but when i draw it on a surface it becomes asif it is  blured !!! i tried to load it using the same size and with filters but same blur prob , check these lines of codes i used and any suggestion would be gr8 , thanks in advance    if (device.DeviceCaps.TextureFilterCaps.SupportsMinifyAnisotropic)  { device.SamplerState[0].MinFilter = TextureFilter.Anisotropic;  }  else if (device.DeviceCaps.TextureFilterCaps.SupportsMinifyLinear)  { device.SamplerState[0].MinFilter = TextureFilter.Linear;  }  // Do the same thing for magnify filter  if (device.DeviceCaps.TextureFilterCaps.SupportsMagnifyAnisotropic)  { device.SamplerState[0].MagFilter = TextureFilter.Anisotropic;  }  else if (device.DeviceCaps.TextureFilterCaps.SupportsMagnifyLinear)  { device.SamplerState[0].MagFilter = TextureFilter.Linear;  }  //Filters used  Filter _MyFilter = Filter.Linear;  // or using Filter.Triangle  Filter _MyMipFilter = Filter.Point;  VB = new VertexBuffer(typeof(CustomVertex.PositionTextured), 8, device, Usage.Dynamic | Usage.WriteOnly, CustomVertex.PositionTextured.Format, Pool.Default);//i tried to load it using both ways   _TArrayButtomBoard = TextureLoader.FromFile(device, Utility.FindMediaFile(@"Media\NewBut\but_0000.png"));// OR _TArrayButtomBoard = TextureLoader.FromFile(device, Utility.FindMediaFile(@"Media\NewBut\but_0000.png"), Salloum.Game.frm.Twidth, Salloum.Game.frm.Thieght, 0, 0, Format.Unknown, Pool.Default, _MyFilter, _MyMipFilter, 0); //and i draw it using the following :device.SetTexture(0, _TArrayButtomBoard );device.TextureState[0].ColorArgument1 = Microsoft.DirectX.Direct3D.TextureArgument.TextureColor;device.TextureState[0].ColorOperation = Microsoft.DirectX.Direct3D.TextureOperation.SelectArg1;device.TextureState[1].ColorOperation = Microsoft.DirectX.Direct3D.TextureOperation.Disable;device.VertexFormat = CustomVertex.PositionTextured.Format;device.SetStreamSource(0, VB, 0);device.DrawPrimitives(PrimitiveType.TriangleStrip, 0, 2);
  I dont think you've included enough details for us to give you a full answer.D3DX can and will resize non 2N images when creating a texture. What are your source dimensions?What texture coordinates are you using? If you're trying to do "2D in 3D" then incorrect texture coordinates combined with filtering will often lead to blurry/distorted results. Check the classic 'Directly Mapping Texels To Pixels' article in the SDK help files. But At a guess your CustomVertex.PositionTextured would suggest this is regular 3D geometry - correct?I'm not sure what your two images are - is the top one the results you're getting (looks a little blurrier) and the bottom one what you wanted to achieve?hthJack   ;  could this also be some auto mipmapping going on?;thanks guys for ur reply , i am using a texture with size 720x576 and i am drawing this texture using a vertex buffer of 4 vertics position textured {-10,0,10} , {10,0,10} , {10,0,-10} , {-10,0,-10} and it is in 3D  and the buttom image is what i want to achieve .and for the filtering i am using  for mipfilters  point filter and for the filter  linear filter and could anyone tell me how to load my images in the best way with the best filtering ??  thanks for all   ;Quote:Original post by jad_salloumi am using a texture with size 720x576That is definitely not 2N - what is the size AFTER you've loaded it. Use IDirect3DTexture9::GetLevelDesc( 0, ... ) and inspect the height/width properties. You might find that D3DX re-sampled it up to 1024x1024. If this is the case, try using D3DX_DEFAULT_NONPOW2 as the height/width when calling D3DXCreateTextureFromFileEx().hthJack
