Create a solid color IDirect3DTexture9
Author
Based on red, green, blue, and alpha only, I would like to create a texture. For, example, I want a half red, and half green texture that is half tranparent, so I would use D3DCOLOR_ARGB(0.5, 0.5, 0.5, 0.0)...
But, from this point on, I have no idea on how to get that D3DCOLOR structure turned into a IDirect3DTexutre9 class or interface.
Just lock the texture and fill in all the texels. You'll need to re-pack your ARGB value into the same format as the texture expects.
Example (Off the top of my head and without error checking):
EDIT: Why do you want to do this anyway? You could probably just use vertex colour

If you're using the texture as a render-target you can use the HW accelerated IDirect3DDevice9::ColorFill() operation...
Otherwise, just use D3DXFillTexture() - it's probably the easiest way and you don't have to mess about with pixel formats and directly locking stuff [grin]

I hooked Counter Strike Source's Set Texture Method for D3D. I first need to learn how to make a solid color texture for the white walls effect, and secondly I need to learn how to make any texture transparent (which I forgot to ask lol)
