D3D9: Loading & displaying an image w/ variable transparency
Author
I'd like to display an image with variable transparency.
I tried using D3DXCreateTextureFromFileEx to load a PNG image and the D3DXSprite interface to display it.
As you can see, everything's fine on this computer (GeForce 2): http://skonet.ivgn.cc/ss1.jpg
However, it won't appear correctly on my old computer (Voodoo 3): http://skonet.ivgn.cc/ss2.gif
Could someone take a look at my project's source code and help me out?

Thanks!
Just from looking at the images, it looks like the Voodoo3 isn't filtering the texture, perhaps because it can't. Could you upload the texture file itself?
Well, don't mind my saying so, but Voodoo3 video cards are garbage. There is a pile of stuff that they don't support. I wouldn't worry about supporting them, unless you want your program to run on older/slower machines.

Is there a way, using DirectX, I could detect whether the video card supports that feature?
Look into the caps of the device, in the SDK its device->GetCaps or just plain GetDeviceCaps, it returns a big structure filled with everything the video vard supports.
