more bpp blues

I've finally got lRBGBitCount in DirectDraw working to some degree like this:

Code:

---

Dim PixelDetails As DDPIXELFORMAT
Dim DepthRate As Long
   
'the bpp of the file
imgBuffer.GetPixelFormat PixelDetails
DepthRate = PixelDetails.lRGBBitCount

---

But it seems that it always returns the bpp or the desktop and not the surface from which the file was created from. :confused:

Any takers? :(
