Hello everyone,
I don't know if anybody's reading these lists anymore (my last question
didn't get any replies whatsoever), but I'll try it once more:
I see the nice example of a sideways window on directfb.org
(http://www.directfb.org/screenshots/LayerWindowRotate.png), and I
wouldn't even need something that complicated: I want to turn the whole
display (because the monitor is used in portrait orientation) by 90 or
270 degrees, so that I get a 1080x1920 display instead of a 1920x1080 one.
I use dfb++, but those are only wrappers for the directfb calls, so that
shouldn't be the problem, I think.
At the moment, I pass "layer-rotate:90" via argc/argv which seems to be
recognized fine, but then I get:
(!!!) *** UNIMPLEMENTED [dfb_surface_create] *** [surface.c:179]
(!!!) *** UNIMPLEMENTED [dfb_surface_reconfig] *** [surface.c:525]
and the display remains in landscape orientation. As far as I can see
from the DirectFB sources (surface.c), rotation is indeed unimplemented
in the surfaces.
My program works like this:
1. I call the Init routine:
DirectFB::Init (&argc, &argv);
2. I call Create():
dfb=DirectFB::Create();
3. I define surface capabilities for a primary surface:
dsc.flags = DSDESC_CAPS;
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_PRIMARY);
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_SYSTEMONLY);
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_DOUBLE);
DFB_ADD_SURFACE_DESC(dsc.flags, DSDESC_PIXELFORMAT);
dsc.pixelformat= DSPF_RGB32;
6. I create that surface:
primary=dfb->CreateSurface(dsc);
All my DrawString(), SetColor(), FillRectangle() etc. operations to fill
the display with the intended information are done in regard to this
primary surface, or they are made on other surfaces I create and then
Blit() to the primary surface. I don't use any window objects as I don't
have a window layout on screen, but just one full-screen display.
What am I doing wrong? Can anyone give me any pointers how to get the
rotation I want to see? 180 degrees works fine, just 90 and 270 don't do
anything.
I even tried to retrieve the primary layer of the display:
prim_layer=dfb->GetDisplayLayer(DLID_PRIMARY);
and rotate that directly:
prim_layer->SetRotation(180);
but that just results in an exception:
IDirectFBDisplayLayer::SetRotation(int) -> Access denied!
So that doesn't work either? Is there another way that I just fail to see?
I'm currently using DirectFB 1.4.17 with DFB++ 1.2.0 running on an Intel
Atom Board using kernel 3.4.9 with modesetting enabled. This is my debug
output:

If you need any further information, just ask. I'm grateful for any help
on the subject, as I'm starting to go nuts here. :-)
