OK It is not explicit but if I read between the lines you are saying these options will be restored in an upcoming version? Or that is not what you are saying.
That's what he's saying.
These functions certainly can't be done automatically. Individual panos need to have ability to adjust individual jpg settings not a global one. More importantly, the ability to resize cube faces is critical especially for large tours. I am working on one with 48 panoramas. At 15000 px equirects times 48 that ends up with a tour around 700MB.
Is 700MB so large?
That is ridiculous that I would want to go and resize all 48 panoramas to get the tour size smaller. Then resize them again if I need to make further adjustments. I prefer to load the full size equirects and have the software resize as needed for possible different purposes. Not all panos need to be rendered at the maximum size available from the equirects even if "multi-resolution" is used
Not sure he's suggesting that you will be able to downsize and set JPEG quality on a per pano basis though.
Would it not in any case be better to use a dedicated graphics program to perform these tasks?
