I could upload a NEF file for other people to try, but I thought I
should say I checked the representations available -
there is only 1.

I don't have experience with NEF files in particular, but RAW files
will generally have a thumbnail of some sort embedded in them. My
guess would be that NSImage, which wraps around ImageIO, is
grabbing this instead of the full-sized image. You can do the
ImageIO stuff yourself using CGImageSource and see if this is the
case.

I've made an app to batch resize images, and all seems perfectly
fine. I can resize JPGs, GIFs, etc etc.
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!
Is this a bug, or do I need to do something different with strange
formats?
Thanks in advance.
