 - (IBAction)copy:sender {        
        NSImage *image = [imageView image];
        if (image != nil) {
            NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];
            [pasteboard clearContents];
            NSArray *copiedObjects = [NSArray arrayWithObject:image];
            [pasteboard writeObjects:copiedObjects];
        }
    }

 - (IBAction)paste:sender {   
        NSPasteboard *pasteboard = [NSPasteboard generalPasteboard];
        NSArray *classArray = [NSArray arrayWithObject:[NSImage class]];
        NSDictionary *options = [NSDictionary dictionary];
        BOOL ok = [pasteboard canReadObjectForClasses:classArray options:options];
        if (ok) {
            NSArray *objectsToPaste = [pasteboard readObjectsForClasses:classArray options:options];
            NSImage *image = [objectsToPaste objectAtIndex:0];
            [imageView setImage:image];
        }
    }
