Hi there,
I am using DFB 1.0.0 on linux.
When ever i do a rendering of PNG image.
Some amount of memory will be taken by the system for rendering,
based on the image size and color content.
But even though i released the image provider and the corresponding surface,
the memory released is not matching with the used.
So, i am facing "out of memory" after recursive image renderings.
Example is below:
#include <stdio.h>
#include <string.h>
#include <directfb.h>
/* DirectFB interfaces */
IDirectFB *dfb;
IDirectFBSurface *primary;
IDirectFBImageProvider *provider;
/* describes size, pixel format and capabilities of a surface*/
DFBSurfaceDescription dsc;
int main( int argc, char *argv[] )
{
system("free");
/* initalize DirectFB and pass arguments */
DirectFBInit( &argc, &argv );
/* create the super interface */
DirectFBCreate( &dfb );
system("free");
/* set cooperative level to DFSCL_FULLSCREEN for exclusive access to the
* primary layer */
dfb->SetCooperativeLevel( dfb, DFSCL_FULLSCREEN );
/* get the primary surface, i.e. the surface of the primary layer we
have
* exclusive access to */
memset( &dsc, 0, sizeof(DFBSurfaceDescription) );
dsc.flags = DSDESC_CAPS ;
/* only the caps field of the description is
valid. height, width and pixelformat are not
set, since the resolution and pixel are
determined by the current video mode */
dsc.caps = DSCAPS_PRIMARY; /* we want the primary surface (the whole
screen) */
/* Since we are in fullscreen mode no new surface will be created,
* the whole screen will be made accessible through a IDirectFBSurface
*/
dfb->CreateSurface( dfb, &dsc, &primary );
system("free");
/* create the image provider that will load the image */
dfb->CreateImageProvider( dfb, "Image31.png", &provider );
system("free");
/* render the image to the screen */
provider->RenderTo( provider, primary, NULL );
system("free");
/* release the image provider, it is no longer necessary */
provider->Release( provider );
system("free");
sleep (5);
/* clean up */
primary->Release( primary );
system("free");
dfb->Release( dfb );
system("free");
return 0;
}
