Anti-aliasing issues on retina

[litchfield]

I'm seeing severe anti-aliasing issues on the edges of transparent png sprites that have been shrunk for the lower ratio versions in retina mode

Is there a way to control the anti-aliasing algorithm being used?

[litchfield]

Also. When using multiple ratios, do I need to ensure all source image dimensions are divisible by the target ratios? Eg for retina, width/height of source images should be even numbers?

Or does glue automatically append whitespace to ensure a clean shrink? So for retina, odd dimensions might automatically pad by one pixel.

Notice the hideous grey lines on the edges of the reduced images.

I'm also seeing this, any ideas?

I've fixed this for me. Try running glue --version see what you have. I only had 0.3!!!

As I'm on mavericks, I had to run sudo env ARCHFLAGS='-arch i386 -arch x86_64' pip install glue --upgrade to get it to upgrade. Non-retina anti-aliasing is all fine for me now.

Hmm, I'm on mavericks too.

glue==0.9.4
Pillow==2.4.0
PIL==1.1.7

libpng: stable 1.5.14 (bottled)

Has anyone solved this problem?
