I'm doing a photo browser of sorts, as part of a larger app. We display a few 
thumbnails, and if the user taps one, they're presented with the full-size 
image.

The problem is that I start with the large images, and when I set them on the 
small UIImageView, they're scaled down and look pretty bad. I have access to a 
better thumbnail-size version of the image, but that complicates the code to 
display them.

I don't see any way of changing the decimation algorithm on UIImageView or 
UIImage, but I did find the minificationFilter on CALayer. Changing that 
setting on the UIImageView had no effect. I also tried different 
minificationFilterBias values, to no effect.

Is there anything I can do, short of doing the interpolation myself?

TIA,
