Hi, I have created a separate surface with DFBSurfaceCapabilities flags (DSCAPS_DOUBLE | DSCAPS_VIDEOONLY). Please refer the attached test code which uses a separate (user) surface for Blit function. After Blitting the user surface into Primary surface it shows black screen instead of blitted image. Any idea about this behavior? Please help to resolve this issue..
Regards,
Vijay

If your requirement is just to have a surface to draw something to be
blitted onto the primary surface later, then you don't really need a
new layer. You can create a new surface and do all your drawings there.
After this you can do a blit onto the primary surface.

Hi,
In our application we are have 2 layers (primary and video layer).. I'm trying
to create
3rd layer via GetDisplayLayer (or CreateSurface) for drawing images into that
and later
we want to blit that surface into primary surface. Please refer the below code
block which we use to create user layer. But it fails. We are unable to test
blit functions. kindly help to resolve this issue.
CreateUserLayer
()
{
IDirectFBDisplayLayer
*pdisplaylayer;
dfb->GetDisplayLayer
( dfb, 2, &pdisplaylayer ); // this api call returns failure
if (ret || !
pdisplaylayer)
{
printf("failed to GetDisplayLayer\n");
return
false;
}
}
