Hi List,
I'm having problems with a software that uses DirectFB for rendering. It
tries to use the DLOP_ALPHACHANNEL option, but after calling to
TestConfiguration a get a failed_flags value of 16, which means
that the option could not be set. I'm using X11 as my backend, with a nVidia
7200 Card. I have GLX extensions enabled.
Do you know what could be the problem?
This is the code:
DFBCHECK(gfxLayer->GetConfiguration(gfxLayer, &layer_config));
wRes = layer_config.width;
hRes = layer_config.height;
/*if ((ret = gfxLayer->SetCooperativeLevel(
gfxLayer, DLSCL_EXCLUSIVE)) != DFB_OK)
DirectFBError("IDirectFBScreen::SetCooperativeLevel",
ret);*/
layer_config.flags = (DFBDisplayLayerConfigFlags)
(DLCONF_BUFFERMODE | DLCONF_OPTIONS);
layer_config.buffermode = DLBM_BACKVIDEO;
* layer_config.options = DLOP_ALPHACHANNEL;*
DFBDisplayLayerConfigFlags failed_flags;
if ((ret = gfxLayer->TestConfiguration(
gfxLayer, &layer_config, &failed_flags)) != DFB_OK) {
* std::cerr << "flags: [" << failed_flags << "]" <<
std::endl;**
DirectFBError(
"gingacc-systemio DFBDeviceScreen TestConfig error:
",
ret);
*
} else {
DFBCHECK(gfxLayer->
SetConfiguration(gfxLayer, &layer_config));
}
}
The output:
