Hi guys

I have run into a bit of a problem where my attempts to load a Offscreen Plain surface from a resource are always met with a result of D3DXERR_INVALIDDATA.

The actual file format is png, the resource type in the RC file is RT_RCDATA, and the surface is created using CreateOffscreenPlainSurface using D3DFMT_A8R8G8B8 and D3DPOOL_DEFAULT.

Here is one of my D3DXLoadSurfaceFromResource functions:

hr = D3DXLoadSurfaceFromResource(mvnl->mTop, NULL, NULL, 
modinst, MAKEINTRESOURCE(400), NULL, D3DX_DEFAULT, D3DCOLOR_ARGB(255,0,0,0), 
&dii);
 

I have made sure that the surface pointer is not NULL, and the module instance is also not NULL. Im starting to wonder if there is not possibly a incompatibility with PNG files and LoadSurfaceFromResource. Or would it be a case of PNG files not being 32bitARGB?

Thanks

JB

I remember I couldn't get D3DXLoadSurfaceFromResource() to work either. I believe the function simply couldn't find the specified resource. Try accessing the resource with the FindResource, LoadResource, LockResource API functions and then loading it with D3DXLoadSurfaceFromMemory().
