Exemple Gimp display function

Hi all,

i works with my DE1 for displaying picture with the Nios II.

I have seen some prepared function for in gui.c and gimp.c

exemple :

/*****************************************************************************
 *  Function: CopyImageToBuffer
 *
 *  Purpose: Copies an image to a video buffer of a different width.  The source and
 *           destination do not have to be contained in the same buffer,
 *           and can be differend widths.  This function is useful for copying
 *           images stored in RAM to the active frame buffer to be displayed.
 *
 *  Returns: 0
 ****************************************************************************/
int CopyImageToBuffer( char* dest, char* src,
                       int dest_width,
                       int src_width, int src_height )
{

/*****************************************************************************
 *  Function: load_gimp_graphic_to_pointer
 *
 *  Purpose:
 *
 *  Returns: 0
 ****************************************************************************/
int load_gimp_graphic_to_pointer( GimpImage* image_source, char** dest )
{

/*****************************************************************************
 *  Function: DisplayGimpImage
 *
 *  Purpose:
 *
 *  Returns: 0
 ****************************************************************************/
void DisplayGimpImage( int loc_x, int loc_y, GimpImage* gimp_image, alt_video_display* display )
{

Did you know a code will use them for an exemple ?

Thanks
