Hi Salim,

could you please check if the option "Interpolate zoomed images" is activated in 'Edit > Options > Appearance...' on your Windows PC? Deactivating this option should result in a rendering as you observe it on your Mac OSX system.

Hope that helps,
Jan

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

Which version of Java are you using? The bundled Java 1.6.0_24? If so, please try with Java 7 and/or Java 8, to see if that helps the situation.

Dear Curtis,

Sadly I don't own a Mac computer to do the test just now. 
I think that when I investigate the problem I had started FIJI with a command line to use the current version of JAVA and the display was still bad. 
I was weeks ago so I should verify my thought.

I will ask a colleague to bring her Mac computer for testing next Monday. If you have any other idea that could help you, you can make me a list of thing to test and could help you.

Best regards,

Salim

Dear Curtis,

I took all the Mac devices I can explore and I found that it might be depending on Mac OS version.

I had two MacBook Air

One is mid 2011 MacBook version, it is up to date and run Mac OS 10.10.3 and have the bad interpolation.

The other is a mid 2013 version and is running and old Mac OS 10.9.5 but this one shows a perfect display like Windows or Linux. 

I tried to run FIJI on the latest version of Java but even with the command I found in the FAQ (/Applications/ImageJ.app/Contents/MacOS/ImageJ-macosx --java-home \
  '/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home' ) FIJI always tell me that it use Java 1.6.

Is it the correct command to run with a specific java version ?

Best regards,

Salim

Yes, but you need to make sure the path goes to your actual Java 7 installation. It is very likely not 1.7.0_45 anymore at this point.

Just take a look:

$ ls /Library/Java/JavaVirtualMachines

And see what is in there. Then use the newest.

Or, you can using the following script:

Dear Curtis,

I removed the \ in the command and I ran FIJI in the 1.8, I think the \ is a error is probably because the command is splited in two lines.

However, with JAVA 1.8 the display is corrected, perfect display like other OS.

So now what is next ? The users will get the good display once ImageJ will be updated to JAVA 1.8 ? Is it going to come soon ? 

Best regards,

Salim

Yes, using Java 8 is the best solution.

We are planning to update the ImageJ downloads (including Fiji) to ship with Java 8 before the end of the year -- ideally much sooner, but the work is rather involved, and things already take longer than you expect...

Dear Curtis,

Just a small additional info,

The last update for Mac OS with java 8 solved the display problem, it is really nice.

I just noticed now that the same problem is shown with Windows 8, the interpolation seems completely broken in windows 8. 
However I know that the solution is already on the road, so it was just to  notify it.

best regards,

Salim
