I have installed DirectFB on my ARM/IMX.
It works, but I have a problem with the colours.
On my development computer (x86), I use the function
like this:
primary->SetColor (primary, RED, GREEN, BLUE,
ALPHACHANNEL);
On my IMX, I have to use the function like this to
obtain the same colours :
primary->SetColor (primary, GREEN, BLUE, BLUE, RED);
Its sure, I can use the function like this. The
problem is when I try to insert PNG pictures.
By exemple, a red picture (FF0000FF = RED=FF,
GREEN=00, BLUE=00, ALPHACHANNEL=FF) become yellow
(GREEN=FF, BLUE=00, BLUE=00, RED=FF) !
Perhaps its a problem with the compatibility of the
ALPHACHANNEL
Thats why I give you the Init of my directFB :
DFBSurfaceDescription dsc;
DFBCHECK (DirectFBInit (&argc, &argv));
DFBCHECK (DirectFBCreate (&dfb));
DFBCHECK (dfb->SetCooperativeLevel (dfb,
DFSCL_FULLSCREEN));
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY | DSCAPS_FLIPPING;
dfb->CreateSurface( dfb, &dsc, &primary );
DFBCHECK (primary->GetSize (primary, &screen_width,
&screen_height));
And my directfbrc :
depth16
RGB16
Could you help me ?
Thank you very much.
