Hi All,
I have been working on a IMX21 based board which has a LCD controller that
can display using 16bpp (5R,6G,5B).
I have written independent application using the frame buffer driver and tries
to write the text with any color combination it's gives me correct.
Now i want to develop the same thing using "DirectFB".
Iam facing a strange problem here.
Problem:
I cannot draw a rectangle with correct color in directfb standalone
application also.
Any help in this will be a great help to me.
Code:
main(){
int i,width;
/*
* A structure describing font properties.
*/
DFBFontDescription font_dsc;
/*
* (Locals)
*/
DFBSurfaceDescription dsc;
DFBSurfacePixelFormat PixelFormat;
PixelFormat = DSPF_RGB16;
/*
* (Initialize)
*/
DFBCHECK (DirectFBInit (&argc, &argv));
DFBCHECK (DirectFBCreate (&dfb));
DFBCHECK (dfb->SetCooperativeLevel (dfb, DFSCL_FULLSCREEN));
dsc.flags = DSDESC_CAPS | DSDESC_PIXELFORMAT;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
dsc.pixelformat = PixelFormat;
DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary ));
DFBCHECK (primary->GetSize (primary, &screen_width, &screen_height));
/*
* First we need to create a font interface by passing a filename
* and a font description to specify the desired font size. DirectFB will
* find (or not) a suitable font loader.
*/
font_dsc.flags = DFDESC_HEIGHT | DFDESC_ATTRIBUTES|DSDESC_PIXELFORMAT;
font_dsc.height = 40;
font_dsc.attributes =0;//DFFA_NOCHARMAP;// 0;//antialias ? 0 : DFFA_MONOCHROME;
DFBCHECK (dfb->CreateFont (dfb, "arial18.bdf", &font_dsc, &font));
printf("\nCreateFont***********************\n");
/*
* Set the font to the surface we want to draw to.
*/
DFBCHECK (primary->SetFont (primary, font));
/* font_dsc.flags = DFDESC_ATTRIBUTES;
font_dsc.attributes = antialias ? 0 : DFFA_MONOCHROME;*/
/*
* Determine the size of our string when drawn using the loaded font.
* Since we are interested in the full string, we pass -1 as string length.
*/
DFBCHECK (font->GetStringWidth (font, text, -1, &width));
/*******************************************/
DFBCHECK (primary->SetColor (primary, 0xFF, 0x00, 0x00,0xFF));
DFBCHECK (primary->FillRectangle (primary, 0, 0, screen_width,
screen_height));
DFBCHECK (primary->SetColor (primary, 0x00, 0x00, 0x00, 0xF0));
DFBCHECK (primary->DrawString (primary, text, -1,0 , screen_height / 2,
DSTF_LEFT));
DFBCHECK (primary->Flip (primary, NULL, DSFLIP_WAITFORSYNC));
/*
* Release the font.
*/
font->Release (font);
/*
* (Release)
*/
primary->Release (primary);
dfb->Release (dfb);
