I was looking at the ROI in the documentation https://gist.github.com/ahankinson/494572, and close by in the same part of the manual was another construction: "VIS means visual masking;" https://ieeexplore.ieee.org/document/901044

I do not have clear whether this 'masking' allows providing a mask, or is some result of locally interpreting of the provided image.

By the way, you'll probably need a good IPS-monitor to see that fuzz in the lower 2 bits. It doesn't show on my old Medion-monitor.

Yes, with Acrobat Reader DC it takes some time to render the foreground, in a fraction of a second I can see lot of fuzzy edges of those letters.

I'm even able to read the fuzz in the background 

If you don't have an IPS-monitor, my Android Phone is also showing it. Outlook voor Android downloaden ________________________________ From: Merlijn Wajer ***@***.***> Sent: Wednesday, November 24, 2021 7:17:42 PM To:...
