Here is my patch.

void Image::Serialize(Stream& s)
{
	int version = 0;
	s / version;
	Size sz = GetSize();
	Point p = GetHotSpot();
	Size dots = GetDots();
	s % sz % p % dots;
	int64 len = (int64)sz.cx * (int64)sz.cy * (int64)sizeof(RGBA);
	if(s.IsLoading())
		if(len) {
			ImageBuffer b(sz);
			
			int64 offset = 0;
			const byte* ptr = (byte*)~b;
			
			while(len>INT_MAX)
			{
				if(!s.GetAll((void*)(ptr+offset), INT_MAX))
				{
					s.SetError();
					return;
				}
				len -= INT_MAX;
				offset += INT_MAX;
			}			
			if(!s.GetAll((void*)(ptr+offset), len))
				s.SetError();
			
			b.SetDots(dots);
			b.SetHotSpot(p);
			*this = b;
		}
		else
			Clear();
	else
	{
		int64 offset = 0;
		const byte* ptr = (byte*)~*this;
				
		while(len>INT_MAX)
		{
			s.Put(ptr+offset, INT_MAX);
			len -= INT_MAX;
			offset += INT_MAX;
		}
		s.Put(ptr+offset, len);
	}
}


I realised that what I was asking would necessitate a lot of rewriting of other code in UPP. I have tested this and it works with an image of 3.45GB.

Can we make this change in the SVN please?

Cheers,

Nick
