[Feature Request] Take a long screenshot when scrolling screen
This is a convenient feature on some ROM but I'm not sure if this is possible for an app. Thanks anyway.
I have been working on this for some time. It's possible but a little difficult. I am not sure if I will get it to work smooth enough to release it 🙄
I want to third this suggestion. My other phone is a newer one with a stock ROM (unrooted) that has a built in "auto-scroll" mode for its screenshot function. It's been really useful (except, it doesn't work with all apps). @cvzi When you say it's "possible," what methods are you thinking of?
My phone has the same auto-scroll mode and it also doesn't work in all apps.
I tried to replicate that mode.
I have tried to use a accessibility service to scroll and then take a screenshot after scrolling. It didn't work because scrolling "one page" was not possible at all: in one app it would scroll a few "lines" and in other apps the same command would scroll several "pages".
I guess I could try to add it with manual scrolling. You scroll with your finger and then tap a button to take a screenshot, then scroll with your finger, then tap a button to take a screenshot and so forth. The app could then combine all the images into one image.

Yeah, the built-in feature has a similar issue, except you can preview its progress and manually stop it short. But, your other option...

...is exactly what I was going to suggest. Sort of like the panorama feature in most camera apps. That might be the easiest route to go. And it may be the best, since you have more room to correct and improve things in the future.
Not adding anything, but until implemented, Stitch on Fdroid can stitch together multiple screenshots into one
Maybe whatever Stitch is using (OpenCV is what the F-Droid page says) could be used as the base for the feature we want here. At least, it could be used for the stitching part, then the auto-repeated screenshots woukd be added in addition to that. Edit: Good find! I'll try it out.
