I saw that DLOP_OPACITY is not supported according to the dfbinfo Output, but DLOP_ALPHACHANNEL is there. Try adding the following here: config.flags = DLCONF_OPTIONS; config.options = DLOP_ALPHACHANNEL; DFBCHECK(osd_layer->SetConfiguration(osd_layer, &config )); If that's not enough you might need to set a pixel format with alpha, too. > DFBCHECK(osd_layer->GetSurface(osd_layer, &primary )); > - osd_layer->SetOpacity( osd_layer, 0 ); You should add the Clear() here instead of SetOpacity(). > DFBCHECK(dfb->GetDisplayLayer( dfb, 1, &bgnd_layer )); > DFBCHECK(bgnd_layer->SetCooperativeLevel(bgnd_layer, DLSCL_EXCLUSIVE)); > bgnd_layer->SetOpacity( bgnd_layer, 255); > DFBCHECK(bgnd_layer->GetSurface(bgnd_layer, &secondary)); > Please run dfblayer to query the default configuration. -- Best regards, Denis Oliver Kropp .------------------------------------------. | DirectFB - Hardware accelerated graphics | | http://www.directfb.org/ | "------------------------------------------" _______________________________________________ directfb-users mailing list directfb-users@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-users
