Hi, My application is as follows: fb0 - OSD fb2 - video If magenta is used on fb0 then this is transparent and the underlying video on fb2 is visible. Any other colour appears drawn on top of the video.
The problem is that the edges of text and images drawn by Directfb appear slightly blurred and appear a pinky colour (Nearly magenta) See this image: http://www.nabble.com/file/p19898305/DistortedImage.jpeg To stop this I am trying to turn off anti -aliasing. Here is my code: DFBFontDescription font_dsc; DFBSurfaceDescription dsc; DFBCHECK (DirectFBInit (&argc, &argv)); DFBCHECK (DirectFBCreate (&dfb)); DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN)); dsc.flags = (DFBSurfaceDescriptionFlags)(DSDESC_CAPS); dsc.caps = (DFBSurfaceCapabilities) (DSCAPS_PRIMARY | DSCAPS_FLIPPING); DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary )); DFBCHECK (primary->GetSize (primary, &screen_width, &screen_height)); //Set Render options for drawing and blitting operations DFBSurfaceRenderOptions render_options = (DFBSurfaceRenderOptions)(DSRO_NONE); = No anti-aliasing for edges primary->SetRenderOptions( primary, render_options ); font_dsc.flags = (DFBFontDescriptionFlags)(DFDESC_HEIGHT | DFDESC_ATTRIBUTES); font_dsc.height = 32; font_dsc.attributes = DFFA_MONOCHROME; //Try to not use anti -aliasing DFBCHECK (dfb->CreateFont (dfb, "times.ttf", &font_dsc, &font)); DFBCHECK (primary->SetFont (primary, font)); DFBCHECK (primary->SetColor (primary, 0xff, 0x00, 0xff, 0)); DFBCHECK (primary->FillRectangle (primary, 0, 0, screen_width, screen_height));//Fill background with magenta DFBCHECK (primary->SetColor (primary, 255, 0, 0, 0)); DFBCHECK (primary->FillRectangle (primary, 50, 50, 100, 100));//Draw a small rectangle on screen DFBCHECK (primary->SetColor (primary, 255, 255, 255, 0)); DFBCHECK (primary->FillRectangle (primary, 200, 200, 170, 170));//Draw another small rectangle on screen DFBCHECK (primary->DrawString (primary, "THIS IS A TEST", -1, 300, 150 ,DSTF_LEFT));//write some text DFBCHECK (primary->Flip (primary, NULL, DSFLIP_NONE)); sleep(10); primary->Release( primary ); dfb->Release( dfb ); -- View this message in context: http://www.nabble.com/Another-anti-aliasing-question-tp19898305p19898305.html Sent from the DirectFB Dev mailing list archive at Nabble.com. _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
