Java codes for RGB images does not work for ImageJ 2
 
|
Dear All,
I used the Java below as part of the codes for white balance. The codes works fine in ImageJ 1.48 but it does not for ImageJ 2. Any advice on how to change it for ImageJ 2 will be greatly appreciated. Thanks.

Hi John,

ImageJ2 is intended to be backwards compatible with ImageJ1. So no changes should be required. The plugin works on my system. Can you please be more specific about how it fails on your system? http://imagej.net/Bug_reporting_best_practices Regards, Curtis On Sun, Apr 5, 2015 at 10:50 PM, LIM Soon Yew John (IMB) < [hidden email]> wrote: > Dear All, > > I used the Java below as part of the codes for white balance.

Hi Curtis,
Thanks for the guideline on bug reporting. I will follow it in the future. And thanks to you, the issue was my copy of ImageJ 2. I had downloaded a fresh copy and it is working.
