Hi All, I am sending this mail with the hope that i would get some reply. I am writing a simple DirectFB application, but when i change the PixelFormat, Iget errors that CreateSurface is Not supported. #include <stdio.h> #include <unistd.h> #include <directfb.h> static IDirectFB *dfb = NULL; static IDirectFBSurface *primary = NULL; static int screen_width = 0; static int screen_height = 0; #define DFBCHECK(x...) \ { \ DFBResult err = x; \ \ if (err != DFB_OK) \ { \ fprintf( stderr, "%s <%d>:\n\t", __FILE__, __LINE__ ); \ DirectFBErrorFatal( #x, err ); \ } \ } int main (int argc, char **argv) { DFBSurfaceDescription dsc; DFBCHECK (DirectFBInit (&argc, &argv)); DFBCHECK (DirectFBCreate (&dfb)); DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN)); dsc.flags = DSDESC_CAPS; /*Now if I Change this line to dsc.flags = DSDESC_CAPS | DSDESC_PIXELFORMAT*/ dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING; /*And Add this line dsc.pixelformat = DSPF_A8 or dsc.pixelformat = DSPF_ALUT44 or, many other Pixel format then i get an error while executing the code the dfb->CreateSurface( dfb, &dsc, &primary ) is not supported.*/ DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary )); DFBCHECK (primary->GetSize (primary, &screen_width, &screen_height)); DFBCHECK (primary->FillRectangle (primary, 0, 0, screen_width, screen_height)); DFBCHECK (primary->SetColor (primary, 0x80, 0x80, 0xff, 0xff)); DFBCHECK (primary->DrawLine (primary, 0, screen_height / 2, screen_width - 1, screen_height / 2)); DFBCHECK (primary->Flip (primary, NULL, 0)); sleep (5); primary->Release( primary ); dfb->Release( dfb ); return 23; } In this code I have to enable Palette Support also, so how can i do this. Can anyone help me out why i am getting this error. regards Animesh Bhadra |
