bits per pixel

Now this seems simple enough, but it doesn't seem to work.....

Code:

---

'first surface is created from file into imgDesc

Dim ImageWidth As Long
Dim ImageHeight As Long
Dim ImageBPP As Long

ImageWidth = imgDesc.lWidth 'this works
ImageHeight = imgDesc.lHeight 'this works too
ImageBPP = imgDesc.ddpfPixelFormat.IRGBBitCount 'this always returns 0

---

0 bpp? :confused:

did you flag the DDSD_PIXELFORMAT bit on dwFlags before passing the DDSURFACEDESC2

If I do this:

Code:

---

imgDesc.lFlags = DDSD_CAPS Or DDSD_PIXELFORMAT

---

When I come to blit the image using Blt, I get invalid procedure call. But blitting works without DDSD_PIXELFORMAT set.

I'm totally confused! :confused: :confused: :confused:
