Interpolated image Imagine having a 10*10 NSImage you want to scale up in an NSImageView to like 100*100. The result will look pretty blurred. That’s caused by the image interpolation of NSImageView which is interpolating the image. This might be fine for most things like photos, when scaling them down or up. But my situation were different, I wanted to zoom into it to visualise the pixels. It took me many hours to find out that most proposed solutions like setting the magnificationFilter to kCAFilterNearest on the NSImageView’s layer are just not working.
