ImageJ with MacBook Pro retina displays

[lechristophe]

I am thinking about getting a MacBook Pro 13" with Retina Display. This
screen has a native 2560x1600 px screen, with various display settings: a
"doubled pixel" resolution of 1280x800, and the possibility to use
intermediate (interpolated) resolutions of 1440x900 and 1680x1050. (native
2560x1600 is not directly accessible without a third-party soft, mainly
because everything gets very tiny).

Whatever the resolution chosen, some applications (like iPhoto) use the
full native resolution to display images (eg it is possible to display a
2000x1000 image in a window with all its pixels at 100% even when using a
120x800 setting). My question is: is it the case for ImageJ on such a
display? If not, for people who use such a screen, is the image quality
acceptable when working with ImageJ with interpolated resolutions (1440x900
or 1650x1080)?

Thanks for your input,

I tested briefly just now, and the answer seems to be yes -- although I
personally have a hard time telling for sure.

Java UI definitely does, in general, take advantage of the Retina display:
- The window frames are crisper
- The ImageJ toolbar is crisper

As for the images themselves, my test was as follows:
- Open Clown
- Zoom out to 50%
- OS zoom in using ctrl+mouse wheel
- Move the Clown image halfway between a Retina display and a non-retina
display
- Clown pixels are obviously doubled/crisper on the Retina

ImageJ 1.x uses Toolkit.getDefaultToolkit().createImage from a
MemoryImageSource internally, which I guess works with the Retina the way
you want... pretty impressive.

I tested on Java 6, 7 and 8 and it seems to work in all three, although
zoom performance in J7 is the worst.

Regards,
Curtis

Hi Curtis,

Thanks a lot for taking the time to test! These are great news.
