The blitting flags for the tmpsurface I have set to:
tmpsurface->SetBlittingFlags(tmpsurface,
(DFBSurfaceBlittingFlags)(DSBLIT_BLEND_ALPHACHANNEL));
And for this surface I'm using the DSPF_ARGB pixelformat.
The srfc surface is a surface which I create from an image with the
imageprovider. Here I set no blitting flags or formats:
IDirectFBImageProvider *imageprovider;
IDirectFBSurface *imgsrfc;
DFBSurfaceDescription imgdsc;
idfb->CreateImageProvider (idfb,path.c_str(), &imageprovider);
imageprovider->GetSurfaceDescription (imageprovider, &imgdsc);
idfb->CreateSurface( idfb, &imgdsc, &imgsrfc );
imageprovider->RenderTo (imageprovider, imgsrfc, NULL);
imageprovider->Release(imageprovider);
Thanks,
Kim
