here I wrote a little function, that should do the job, too:

Code:

---

void create_flare(BMAP* picture)
{
	VECTOR picture_size;
	VECTOR paintPos;
	int i;
	int format;
	float pixel;
	picture_size.x = bmap_width(picture);
	picture_size.y = bmap_height(picture);
	format = bmap_lock(picture,0);
	for(i=0;i<picture_size.x*picture_size.y;i++)
	{
		paintPos.x = i%picture_size.x;
		paintPos.y = (picture_size.y-1)-integer(i/picture_size.x);
		pixel=pixel_for_bmap(picture,paintPos.x,paintPos.y);
		pixel_to_vec(temp,NULL,format,pixel);
		pixel = pixel_for_vec(temp,(temp.x+temp.y+temp.z)/3/2.55,format);
		pixel_to_bmap(picture,paintPos.x,paintPos.y,pixel);
	}
	bmap_unlock(picture);
}
