I've used an NSTableView as the source of the images, the user
drags all the files they want resizing into it.
I used [NSImage imageFileTypes]; to allow them to only drop files
that NSImage can use.
However! When I drop on a NEF (Nikon RAW) file, it gets the size
totally wrong, I even outputted the image as loaded from disk
into an NSImageView, and it's tiny. The pictures are from a 7
megapixel camera, and look fine in Preview, but in my app, they're
the size of the thumbails shown in Finder!
An NSImage's size isn't necessarily its width and height in pixels.
You may have to set the width and height to the pixelsWide/pixelsHigh
values of the NSImageRep in the NSImage to get it at a size where
each pixel is equivalent to a unit. If the NEF file specifies its
resolution as, say 360 dpi, it wouldn't be surprising that it might
show up as rather small.
