Creating Textures

Alright, I ''attempting'' to create a texture generation tool, and I can make it create a ''Bitmap'' file type. Now, I''m using C# and trying to create a Texture using this Bitmap filetype. TextureLoader only takes files (grrr), so I''m stuck using "new Texture(blah);" So, my code looks like this. Texture t = new Texture( device, myBitmap, 0, Pool.Default ); And that keeps throwing errors, even if my bitmap is a perfect square power of 2... So, how does one just dynmically make a texture? (Only thing I''m thinking of doing is writing the Bitmap to a file, than loading it back... but that seems like cheating.)
