Quick Scan Landscape Mode #59

Open ghost opened 2 years ago

ghost commented 2 years ago

Issue: Quick Scan

when operated in potrait mode, causes first image to appear as potrait and the rest in landscape
when operated in landscape mode, works as expected

Device: Samsung Galaxy M21

Temporary fix: Even though the Device camera appears in potrait, the image appears in landscape.

Temporary fix found on my device is that for every scan of a page, calibrating the accelerometer by shaking it once in the vertical direction detects gravity properly and fixes the landscape problem.

Could you share a video recreating the problem?

Could you share a video recreating the problem?

Actually it comes up at random times, i should have given a reference screenshot.

Here, I managed to recreate it once And no, the "Temporary fix" that i talked about did not work how much ever i tried

All pictures were taken in potrait mode of camera, but only the first appears as such.

Does this issue occur only when using quick scan?

Yes

We have tested it multiple Samsung devices but could not recreate this problem. I guess it should be a problem with the phone's camera. If not, share a video recording recreating the problem.

Edit: This should be a problem with Samsung Software - Try this fix

I just tried this app on my Poco X3 and used Quick Scan in portrait mode. The app works fine, however when I open the saved pdf file in any pdf viewer app, all pages appear rotated 90° ccw (landscape mode). Not sure if I'm doing something wrong.

@eleius Are the images in landscape mode only in pdf or also in the app? like this

eleius commented 2 years ago

@vikram0230 in the app they're shown in portrait mode, only pdf pages are shown in landscape mode (in pdf viewers)

vikram0230 commented 2 years ago

Does this occur with normal scan and importing from gallery? And could you share a recording recreating the problem?

eleius commented 2 years ago

In normal scan + import from gallery the resulting pdf is ok. It only occurs when using quick scan > export > save to device (pictures are in portrait mode in the app, but the resulting pdf has all pages in landscape mode... I tried several times, taking 3 pictures every time)

eleius commented 2 years ago

I just tried again, this is a screenshot inside the app, and here you can download the resulting pdf.
