Dear All,
My name is Amaresh. I am working as a junior engineer in Altech UEC on STB
domain from past 6 months. I am very much interested to learn directfb.
I have installed directfb library on my virtual machine fedora 12.
I am trying to load sample png image and display it.
i got the following code from the net sample2.c
#include <directfb.h>
#include <unistd.h>
IDirectFB *dfb;
IDirectFBSurface *primary;
IDirectFBImageProvider *provider;
DFBSurfaceDescription dsc;
int main(int argc, char *argv[])
{
DirectFBInit(&argc, &argv);
DirectFBCreate(&dfb);
dfb->SetCooperativeLevel(dfb, DFSCL_FULLSCREEN);
/* Primary */
memset(&dsc, 0, sizeof(DFBSurfaceDescription));
dsc.flags = DSDESC_CAPS;
dsc.caps = DSCAPS_PRIMARY;
dfb->CreateSurface(dfb, &dsc, &primary);
/* Background */
dfb->CreateImageProvider(dfb, "/home/amaresh/hello/sample.png",
&provider);
provider->RenderTo(provider, primary, NULL);
provider->Release(provider);
sleep(5);
primary->Release(primary);
dfb->Release(dfb);
return 0;
}
i have compiled using below command
# cc sample2.c -I /usr/include/directfb/ /usr/local/lib/libdirectfb-1.7.so.0
# ./a.out
