Mam nast�puj�cy problem. Chc� wczyta� z pliku graficznego surface i wrzuci�
go do back buffera. To samo w sobie nie sprawia problemu. Problemem jest
zmuszenie Directa aby uwzgl�dni� kana� alpha.

Poni�ej zamieszczam wycinki kodu:

Wczytywanie:

LPDIRECT3DSURFACE9 sBB;
m_pd3dDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &sBB);
D3DSURFACE_DESC desc;
sBB->GetDesc(&desc);
m_pd3dDevice->CreateOffscreenPlainSurface(desc.Width, desc.Height,
desc.Format, D3DPOOL_SYSTEMMEM, &fgSurface, NULL);
D3DXLoadSurfaceFromFile(fgSurface, NULL, NULL, filename, NULL, D3DX_DEFAULT,
0, NULL);

Renderowanie:

LPDIRECT3DSURFACE9 sBB;
m_pd3dDevice->GetBackBuffer(0, 0, D3DBACKBUFFER_TYPE_MONO, &sBB);
D3DXLoadSurfaceFromSurface(sBB, NULL, NULL, fgSurface, NULL, NULL,
D3DX_DEFAULT, D3DCOLOR_ARGB(255,0,0,0));

Jakie� rady, sugestie?

pozdrawiam
Erge
