Hi Philippe,

Thanks for your feedback. Thats true, saving recognised text together with the scanned image is currently out of the scope of presented functionallity. It would be very helpful if you could describe how you see it. We are very opened to accept suggestions/recommendations from our users. Feel free to submit a Feature Request.

Hello Pavel


Some problems I met and I would like to share:


1) the grips for modifying an image (crop/sale/perspective) are very small and often my finger press/click an icon (ocr/ upright- or scale/crop/perspective-down left)


2) when I modify a picture (filter or* crop or scale...) in order to enhance the success of ocr-ing text or just scan the interesting part, I apply filter, crop,...but after It's impossible to save the modified picture.

And when ocr is launched,* all the picture is scanned despite it was modified before.

3) please display the the active langage on the ocr icon. Long press on the ocr icon swipe the langage.*

4) When I press on save, app answers nothing to save even I modify a picture!
So it's difficult to understand the save feature:
-Save original picture?
-Save modified picture?
-Save for transforming into pdf? So why not have a icon 'scan pdf' in order to pdf-ise directly
-Save recognised text?

I send you several crash report of you


Best regards

Thanks for sharing, Philippe

In the same order you have asked:

1) the grips for modifying an image (crop/sale/perspective) are very small and often my finger press/click an icon (ocr/ upright- or scale/crop/perspective-down left)

It is not neccesary to press grips at all, app detects the closest grip to your finger and then you just move it as you wish. Just position your finger somewhere near the grip and try to move it. You will see that it works even though you are not pressing on the grip directly. We hope this is more convenient to user, than pressing exactly on the grip

2) when I modify a picture (filter or* crop or scale...) in order to enhance the success of ocr-ing text or just scan the interesting part, I apply filter, crop,...but after It's impossible to save the modified picture.

This is strange. It works on all of our testing devices. Can you please describe the exact order of operations to reproduce this bug?

3) please display the the active langage on the ocr icon. Long press on the ocr icon swipe the langage.*

Click to collapse

Ok, we will think about that

4) When I press on save, app answers nothing to save even I modify a picture!

Save button in this window should just save ANY changes you have applied to the image. It appears beeing related to second problem you have mentioned. Can you please describe the exact order of operations to reproduce this bug?

Hello Pavel



1) it's OK. It's just question of training...but it's not evident for the first time.


2) OK I understand:
a) you click on edit then
b) you can modify the picture (crop/scale/perspective) with your finger. In order to 'apply' your modifications you click one more time on the crop/scale/perspective or filter icon.
c) then you can save definitely the modified picture.

But you lose original picture! May be it will be interesting to keep original if you want to do modifications later *on the original picture.



3 ) OK. Super!


4) related to 2). I sugest : Press on save icon saves modifications or results of the moment => If you modify the picture it saves the modified picture , if you do ocr, it saves the recognised text, if you pdf-ise a picture, it save the pdf. For the original picture, I suggest that it saved by default.*


I suggest also that in the "new document" view, you can see the original picture in a small vignette (as actual) but you can access (long press /swipe) to all saved objects (modified picture/ ocr text/ pdf / jpeg) related to the vignette.

5) After OCR, the app propose directly to share the result of the ocr process ! But may be, before sharing, I want to check the result of the ocr process and correct letter / sign /word that wasn't correctly recognised. So, I suggest before sharing the result of the OCR process, that the app :
a) shows the recognised text in first,
b) allow to corrects mistakes, (==> learn feature from mistakes and correction)
c) save the results
d) and then share

Note : when you share an ocr text with some app, the app opens but the ocr text didn't paste (cf memo app on note 2 - KK 4.4.2).

6) Same suggestions with transformation in pdf or jpeg : after pdf process, the app directly propose to share the pdf / jpeg with external app. But before, I want to check if the pdf/ jpeg is OK before Sharing. I want to save the pdf / jpeg in order to use it later. (the pdf appears in the RecentPages directory). So why not to display it in the new document view of the app ?

Hi Philippe,

It is good to hear that Save button actually works as it should. Regarding your comments:

c) then you can save definitely the modified picture.

But you lose original picture! May be it will be interesting to keep original if you want to do modifications later *on the original picture.

yes, when you press Save button after you have edited image the edited version will be saved and replace the original one. We think about adding a new "filter", which will revert all changes and switch the image to the original picture.

4) related to 2). I sugest : Press on save icon saves modifications or results of the moment => If you modify the picture it saves the modified picture , if you do ocr, it saves the recognised text, if you pdf-ise a picture, it save the pdf. For the original picture, I suggest that it saved by default.*

We have thought about that as well, this behaviour will be implemented in one of the next versions

5) After OCR, the app propose directly to share the result of the ocr process ! But may be, before sharing, I want to check the result of the ocr process and correct letter / sign /word that wasn't correctly recognised. So, I suggest before sharing the result of the OCR process, that the app :

Well, it is a good idea itself, but we thought that one would prefer to correct/modify text in some existing text editor. So, at the current stage of app development, we would prefer to include support for different text editors rather than coding our own. However, we will keep your suggestion in mind.

Note : when you share an ocr text with some app, the app opens but the ocr text didn't paste (cf memo app on note 2 - KK 4.4.2).

Can you give a link to the app? We will test

Actually you can open PDF for preview before you send it. Check Options and set "Open PDF" to "On".
Regarding JPG: In the main ("New document") window press on the picture icon, it will open another window where you can preview or edit image again if neccessary

"about adding a new "filter", which will revert all changes and switch the image to the original picture"
==>instead of "cancelling all changes", Why not just offer the possibility to cancelled sellectively the last change in order to choose the best change + a possibility to compare with the original picture in order to decide if the current change is the best chang.

Not going deep into details, there are some technical limitations to achieve that.

"Well, it is a good idea itself, but we thought that one would prefer to correct/modify text in some existing text editor.

==> the problem is not if I can modify ocr text with embeded or internal editor but to hav possibility to check (with internal or external editor) the result before sharing !

Thats true, but all of these apps usually have 'Share text' option, dont they? Our main idea is just to allow the user to use recognised text in other apps, where he/she can edit it and then share.

We are working on a new update already, i'll post a message once it is out

Pav

Thank you

1) Until the bug isn't solved: when download langage pack, dysplay a short message "wait until the langage pack is really installed"

Click to expand...

Click to collapse

I do agree, this should be improved

2) after "ocr " ing a text : the recognised text should be saved "as a note/comment" with the scanned text. Then I could :
-paste the recognised text into other app like office app,
-share quickly with an other app: mail, message, note...

I think it makes sense to save recognized text and to associate it with the image.
We are currently working on the update to include some improvements discussed above. There is lots of work, plaease understand that its challenging to add new features immediately. However let me reassure you once again that we always keep suggestions from our users in mind and are constantly working to make the app better

Regards,
Pavel
