Hi,
I have a large image jpg I display in a NSImageView.
I resize the NSImage then I store it to an NSDictionary, as NSData, but
later, when I recall it and display to to a NSImageView, it has the same
original dimensions. I guess I didn't scaled the image but only the way it
has been shown.

Instead I want to store only a small scaled image (Thumbnail) of the
original image. How can I do?


Create a new NSImage the size of the thumbnail
lock focus on it
draw the big image into the thumbnail rect
unlock focus
save the thumbnail image
