NSImageView setImageScaling:NSScaleToFit blurs image

I have a series of tiny (32x32) PGM image astronomical IR data in memory that I display on screen zoomed up to 640x640. Right now Im using a NSImageView and setImageScaling:NSScaleToFit. This works but some sort of gaussian blur gets applied to the image ruining the analysis.

Is there a setting to turn off this default blur or is there another way I can zoom display a small image (QCView?) but without the blur? The net effect of what we need is a sharp pixellated image not one where the pixellated block edges are smeared.

OSX 10.5.2, Xcode 3.0, ObjC 2.0
