The vendor blobs in custom ROMs come from the stock vendor ROM. When the vendor stops publishing their stock ROM, the custom ROM's will also stop coming. In some cases some BLOBs can be taken from similar devices that might be supported a bit longer but I believe this is quite rare.
The ROM itself still gets updates through the AOSP but vendor BLOBs stay where they are and open source devs can do little to nothing about that.
For the first year or two, that's common. Getting feature updates for anything even approaching >5 years is near unthinkable for Android devices however. You only get that with custom ROMs and even there it's only half of the story as they can't provide security updates for vendor blobs which is kind of a big yikes.
The iPhone 8 will get cut off the newest feature updates in the upcoming iOS 17; 6 years after launch. Security updates will likely be available for years to come. For comparison, my OnePlus 5 from 2017 (1 year younger) received its last update (any update whatsoever) in 2020 (3 years ago).
With an Android device, you'd be lucky to get security patches in any regularity at all, much less >3 years after release. That only happens with a couple few vendors who actually care such as Nokia and maybe Google (to a degree).
Dann lernt man daraus und macht sie nächstes mal nicht ;)
And how do you encode the images of the scan contained in the PDF/A? That's the crux here.
Yes, as I said.
As also mentioned in the post, I need a solution for multiple pages and an image (no matter what format) only represents a single page and WEBPs don't go into PDFs.
I don't see how that point is relevant as that claim was never made.
The claim was that Android phones usually barely get updates which maps to my experience. Updates more than one or two years after the release of a device is the exception, not the norm.
Yeah, like, I press upvote and I get no spinner. How crazy is that?!
Great job devs :)
Hmm, I'm using grayscale PNGs as my baseline here. A 150dpi scan is about 1.3MiB.
A (for the purpose of text documents) similar quality WEBP is about 1/4 of that.
Not sure why this is downvoted so much. These are very valid points.
I use SANE, then do lossy compression too.
Well, what kind of lossy compression? JPEG?
IME, JPEG looks quite terrible for text documents -even at q=95.
How do you handle multiple pages?
