Description (last modified by curtis)
Boats.gif appears more contrasty than the IJ1 version.
I've confirmed that it's not just a different image file by saving the image to my desktop from IJ2 and reopening it in IJ1... it still looks different.
This display issue hasn't been limited to this one file and is a huge problem, especially for testing functionality of other commands and plugins.
Additional sample images that render differently in IJ2:
- CT (420K, 16-bit DICOM) — significantly less contrasty in IJ2
- Dot Blot (7K) — appears darker or more contrasty (subtle) in IJ2. Look at the dark spot at grid position (4,4)
- Gel (105K) — appears lighter in IJ2
- HeLa Cells (1.3M, 48-bit RGB) — appears darker in IJ2
- Mitosis (26MB, 5D stack) — significantly darker in IJ2
- Neuron (1.6M, 5 channels) — All channels appear darker and less contrasty in IJ2
- TEM Filter (112K) — Image is slightly darker in IJ2 (8 bit)
- Tree Rings (48K) — Image is lighter in IJ2

This ticket does not fit the beta4 theme of plugin work. It will fit in marginally better with the beta5 theme of flexible data handling.

I'm not sure how Adam captured these images, but note that the IJ2 screenshot plugin distorts colors also, see trac #1576. So these screenshots are certainly valid for comparing results but the colors may differ from an actual 'live' IJ2 window.

- Status changed from assigned to closed
- Resolution set to fixed
Quite a while ago the legacy layer was changed to use IJ1's display range settings when possible. So opening these images via Open Samples results in the same views with no apparent differences. Saving these images to disk and opening them in IJ2 via the Open command will likely have display differences as our current DefaultAutoscaleMethod does not match IJ1's approach. There is already a ticket for that (#794) and so I am closing this ticket as fixed.
Same image loaded in IJ2 (left) and IJ1 (right), note the contrast difference.
