Dear all,
I working under DirectFB-1.1.0 and window manager SaWMan-0.2.0
When I create a window and set its opacity to 0xff, then the pixel format of
my window surface will change to ARGB.
Then I got a wrong screen output.
I traced into the sawman_wm.c and print some information in it and
re-compile it.
I found that ...
Line 811 in sawman_wm.c:
config.flags = DLCONF_WIDTH | DLCONF_HEIGHT |
DLCONF_PIXELFORMAT | DLCONF_OPTIONS | DLCONF_BUFFERMODE;
config.width = single->src.w;
config.height = single->src.h;
config.pixelformat = surface->config.format; <-------
I print it out, I got DSPF_ARGB, why?
config.options = options;
config.buffermode = DLBM_FRONTONLY;
dfb_layer_context_set_configuration( tier->context,
&config );
dfb_layer_context_set_screenrectangle( tier->context,
&rect );
P.S. I didn't assign pixel format when I create the window.
