Dear Jan,



In both screen capture the "interpolate zoomed images" are activated (MacOS and
Linux). 



The Interpolation is not completely broken in MacOS, when I activate and
deactivate it, I see some changes but the interpolated image is far less
quality in MacOS than other OS.



I work with Ilan Tal for the PET/CT viewer, we tried to change rendering
parameter in his plugin, in Windows and Linux the display is really good but in
MacOS we always have those pixelized images probably due to a lower
interpolation. 



In our thought, the problem may be related to JAVA2D that seems to give lower
quality in MacOS than other OS. In Mac OS documentation for developer it seems
that Apple provides different API for rendering like Quartz but we wasn't able
to use it since Mr Tal don't have a Apple computer to use those specific
library (I may not understood all those technical stuff). 



However I wonder is those Mac specific rendering could be solved into ImageJ
itself. It is really nice to have a cross platform software but having a lower
image rendering for Mac users is annoying.



Best regards,



Salim
