Oops, sorry, didn't notice your tmo handle in the url, and THANKS! Awesome app!

Re: OCR on jolla

This really is great (except it throws an error when using screenshots, might need to change output format if possible), having only ancient greek/maths and english it still recognized half of a greek airport sign (english parts in higher percentage), the brussels sign to throw paper INTO the toilet (seemed funny as most of the time it was reverse, don't clog our precious pipes), sadly 0 accuracy, but it was in weird font anyway. When will realtime OCR/translation come? :D

edit: just an extract I find amazing:

Code:

Litterin‘g in the terminal is not permitted. Please dispose of cigarette butts,gUm,y 1

etc in the rubbish bins provided and make proper use of the bins separating, plastic



and. paperfrom other trash.

(don't ask me why it is turned around, gallery upload to twitter? (photofunia had similar bug with initial pre-4.29 release) or the textractor is impacted, not sure)

The error was related to too low resolution and it is fixed now. I haven't tested yet properly other formats than jpg.

I'll check why images gets mirrored.

Re: OCR on jolla

Thanks! (weird thing is that image still displays properly in gallery, but after textractor went through it and gallery upload to twitter it ended up turned sideways (just checked with fresh image from gallery, behaves as expected), yeah some things in jolla work in mysterious ways C: )

Can you give the steps how to reproduce this? I found one rotation bug (when usb port was pointing to right) in which the image was rotated too much but this is not the same one.

I tried to reproduce that mirroring issue by uploading some images taken in Textractor/selected via Textractor to Twitter and everything worked correctly. Did you scale the image before upload in the gallery app and did you take the image in Textractor or did you select the image?

edit: yeah, tried to reproduce, but bukowski's quote is oriented correctly (opening the image by the app 'modifies it' as in shuffles to the top of available options, even if nothing was done with it)

Re: OCR on jolla

Aaaah and got it, picture from mexico I took (no text, just for test:
https://twitter.com/szopin/status/60...479424/photo/1
This got turned left-right, this is the resulting B/W OCR image (already turned) https://twitter.com/szopin/status/60...356288/photo/1 )

Yes, it shuffles to the top of options because it is actually modified even if you see message "An error occured. Image could not be preprocessed." because before preprocessing the image is opened, the dots per meter value is changed and rotation is applied if necessary -> original image is overwritten by these changes.
