Matteo Bruni (@Mystral) commented about dlls/d3dx9_36/tests/surface.c:
+ /* R and G channels converted to SNORM range. */ + SetRect(&rect, 0, 0, 2, 2); + hr = D3DXLoadSurfaceFromMemory(surf, NULL, NULL, pixdata_a8b8g8r8_2, D3DFMT_A8B8G8R8, 8, NULL, &rect, + D3DX_FILTER_NONE, 0); + todo_wine ok(hr == D3D_OK, "Unexpected hr %#lx.\n", hr); + + hr = IDirect3DSurface9_LockRect(surf, &lockrect, NULL, D3DLOCK_READONLY); + ok(hr == D3D_OK, "Failed to lock surface, hr %#lx.\n", hr); + todo_wine check_pixel_2bpp(&lockrect, 0, 0, 0x9282); + todo_wine check_pixel_2bpp(&lockrect, 1, 0, 0xd2c2); + todo_wine check_pixel_2bpp(&lockrect, 0, 1, 0x1000); + todo_wine check_pixel_2bpp(&lockrect, 1, 1, 0x5040); + hr = IDirect3DSurface9_UnlockRect(surf); + ok(hr == D3D_OK, "Failed to unlock surface, hr %#lx.\n", hr); + + /* Copy the V8U8 channels. */ "Copy" here is a bit misleading given that 0x80 and 0x81 values are both nudged to 0x82.
