Can anyone point me to some sample code that illustrates:

1.) Drawing a partial segment of a source image (png) to an NSImageView
2.) Drawing a partial segment of a source image (png) to a Custom View

Here is a little of what I am trying to get to work (using the NSImageView approach):

Code:

- (NSImage *)drawCard

{

    NSImage * cardSheet = [[NSImage alloc] initWithContentsOfFile:@"cardSheet.png"];

    NSSize cardInSheetSize;

    cardInSheetSize.height = 70;

    cardInSheetSize.width = 50;

    NSRect srcRect;

    (srcRect.origin).x = 0.0;

    (srcRect.origin).y = 0.0;

    srcRect.size = cardInSheetSize;

    NSRect dstRect;

    dstRect.origin = NSZeroPoint;

    dstRect.size = cardInSheetSize;

    NSImage * card = [[NSImage alloc] initWithSize:cardInSheetSize];

    [card lockFocus];

    [cardSheet drawInRect:dstRect fromRect:srcRect operation:NSCompositeCopy fraction:1.0];

    [card unlockFocus];

    return card;

}

I am calling it with:

Code:

[nextCardImage setImage:[deck drawCard]];

nextCardImage is an NSImageView Outlet.

Thanks for any help.
