Cannot load textures from memory

Hi all

I have a problem with loading a texture from memory.
I use this code:

Code:

    
Stream &#58;= TMemoryStream.Create;
    try
      fBitmap.SaveToStream&#40;Stream&#41;;
      if fFormat = pf16bit then
        fmt &#58;= D3DFMT_R5G6B5
      else
        fmt &#58;= D3DFMT_A8R8G8B8;
      &#123;create texture from memory&#125;
      HR &#58;= D3DXCreateTextureFromFileInMemoryEx&#40;Graphic.fD3DDevice,
Stream.Memory,Stream.Size,0,0,0,0,
fmt,D3DPOOL_DEFAULT,D3DX_FILTER_NONE,
D3DX_DEFAULT,fTransColor,nil,nil,fTexture&#41;;
      if Failed&#40;HR&#41; then
      begin
        //Report error....
      end;
    finally
      Stream.Free;
    end;

The function returns D3DERR_INVALIDCALL but i cant figure out why,

Can anyone help me??
thanx

P.S [pascal][/pascal] doesn't seem to work

Maybe that is bacause you are trying to create texture with dimentions WxH = 0x0? Nil texture? :shock: :lol:
Please read decription of this function and it's parameters in documentation.

Btw, why are you using Ex variant of function?

I've done that and it says:

Width
[in] Width in pixels. If this value is zero or D3DX_DEFAULT, the dimensions are taken from the file.
Height
[in] Height, in pixels. If this value is zero or D3DX_DEFAULT, the dimensions are taken from the file.

So that shouldn't be the problem.

Even when i do:

Code:

      &#123;create texture from memory&#125;
      HR &#58;= D3DXCreateTextureFromFileInMemoryEx&#40;Graphic.fD3DDevice,Stream.Memory,Stream.Size,
                      fBitmap.Width,fBitmap.Height,0,0,fmt,D3DPOOL_DEFAULT,D3DX_FILTER_NONE,D3DX_DEFAULT,fTransColor,nil,nil,fTexture&#41;;

The bug is still there.

I am using the ex version because i want to set the transparent color and the format/filtering/mipmapping settings for the texture.
I'll implement these later.

Do you know a way of fixing this?? :?
