Hi OME team,
In order to show object classifications after analysis I am generating a single mask ROI for each of the identified classes. These ROIs are the same size as the image so they show as an overlay that can be easily turned on and off using iviewer with a single click. However, this works fine for images (and thus mask ROIs) up to about 3000 by 3000 pixels but when the image (and ROI) is larger I get no error but the mask does not display in iviewer or in the old-style viewer. The ROI shows up in the list and its border high-lights when selected and the “Show” checkbox appears to work but the mask ROI itself does not show in the display.
For generating the mask ROIs from my classification masks, I’m using a modified version of the example Python code on: https://github.com/ome/openmicroscopy/blob/v5.5.1/examples/Training/python/ROIs.py
Is there a built-in limit that silently stops large mask ROIs from appearing? If so, can that limit be increased?
