You can use NSScrollView:

    NSScrollView* scrollView = [[NSScrollView alloc] init];
    [scrollView setHasHorizontalScroller: YES];
    [scrollView setHasVerticalScroller: YES];
    self.contentView = [[NSView alloc] initWithFrame: NSMakeRect(0, 0, 1.0e7, 1.0e7)];
    [self.contentView addSubview: [NSImageView ...]];        
    [self.contentView addSubview: [NSImageView ...]];        
    ...
    [scrollView setDocumentView: self.contentView];
    self.view = scrollView;

Or use Minimum Size for Window.
