Since easyOCR / google has a way better support for non-latin languages, it'd be great if the addon is engine agnostic.

Hello,

when im trying to to use the ankiocr I'll get an error message on some cards . Not on every card but on such which have a special letter like "ä ö ü" in the name of the card.

For example:
If the cards name is: "Hola ÜK.jpg" it will not work

This is the error message:

Hi,

Sorry to be the bearer of bad news.
The new version doesn't seem to work all that well. As with the previous version the gui completely freezes when running OCR, so I can't really know if it's progressing or not on large collection. But overall this seems WAY slower than before. I tried lowering the batch size to 1 to try and see if it worked better but it didn't change a thing.

I am pretty sure it just runs in circle at some point when I scan more than 2 batches at once but I can't know if the progress bar doesn't appear.

It would be great to have the progress bar work. This way we could also have a "cancel" button, otherwise I had to force quit anki and manually kill each tesseract process.

Displaying the time it took to run at the end would be helpful too to organize myself when I want to scan a huge deck but that is minor.

System : ubuntu 18 with anki 2.1.35

It would be nice if there was an option to add a "OCR" tag and if a user attempts to process the same cards twice, cards with the tag are skipped. Thanks!

Hello Chris,
Anki OCR is working for me as long as I use "tooltip" option as output location.
When I am switching to "new_field", Anki is crashing.
Is there a solution?
regards,
Philipp

Hi,

I noticed a very annoying issue. Sometimes an image is not really in collection.media but is actually a link to an image, that anki fetches.

When you have a card like that and run AnkiOCR on a large collection that includes it, it will go through all the selected cards then show a cryptic error and most importantly won't save any of the OCR'd cards that have not faileed.

To solve those issues I have to read the error, then find the card that uses this image, then manually use an image instead of a link, then re run OCR on all the cards.

I think AnkiOCR should at least ignore the links, or fetch the image and OCR it then store the plaintext as usual without saving the media.

In any case, is there no way to not have done the OCR for nothing? It can take quite come time to run.

Here's the error message :

Thanks!

Hi,

Not really a trick but I figured that I could use re"<img *WORD*" to search for cards that contain this word in a picture.

Also, -"re:(<img.*title=.*)" "re:(<img.*>)" shows you cards that contain pictures that have not been OCR'ed. But beware, it won't show cards that contain multiple pictures if only some of them have not been OCR'ed, for example if you added one of the image later.

I think this should be mentionned in the README and in the addon page as it could be quite useful to people.

Have a nice day!

Hi, AnkiOCR doesn't work, I have this error when trying to run it on a note. It only works when I run it on a note without image lol

Can you help me please ? I'm on macOS 14.0

I had problems recognizing text on bright background colors and I found the solution in the thread below:

tesseract-ocr/tesseract#1990

I'm not from the programming area and to solve my problem, I changed the line below in the file C:\Users\xxxxx\AppData\Roaming\Anki2\addons21\450181164_vendor\pytesseract.pytesseract.py , but I believe that a parameterizable and more professional solution is possible.

cmd_args += (tesseract_cmd, input_filename, output_filename_base, '-c', 'thresholding_method=2')

Thanks again for this amazing addon.

Hi,

I just pushed a hackish module that wrapps pytesseract to preserve the spacing as much as possible.

Here's the link: https://pypi.org/project/OCR-with-format/

If you manage to find the time to include it in your repo I think it would be nice :)

Here's the basic usage:

import OCR_with_format
 OCR_with_format.OCR_with_format(img_path="./test.png", quiet=True)

Thanks and have a nice day!

Just installed the addon.

Im using Anki version 2.1.42.

Description:
I would like to suggest integrating PaddleOCR as an alternative to Tesseract for OCR tasks. PaddleOCR provides several significant advantages, including robust multilingual support, the ability to leverage GPU acceleration, and superior layout handling capabilities. Additionally, it could be relatively straightforward to package, which could simplify the integration process.
Benefits:

• Multilingual support
• Optional GPU acceleration
• Layout and table handling
• Easy to package?

Link: PaddleOCR GitHub

Hi,

I was curious as to if you tried to keep layout when OCRing the image.

I find information on the internet that gives me hope that it's possible

I don't need this myself I think but I can imagine people asking for this.

I would gladly do a PR if I managed to pull it off but I can't make your addon work for now.

Some image gone missing after OCR, leaving only the text.

I've checked the file and found out that these pictures' style were left blank which caused this issue, I've already manually edited each card and recovered all media, just want to leave this info here for the dev to check it out and for anyone that might have similar problems.

Hi,

Just a quick heads up to point out that if an image contains "::" in the text, it will break clozes as it will appear as a hint.

Not sure of how to best handle this case though.

Have a nice day!

would you consider updating the AnkiOCR add on for the newer anki versions?

Hi,

In case you didn't know, there seems to be a limit to how many cards the user can send to AnkiOCR, it's a minor annoyance to me as I often share very large decks with colleagues.

Here's the error :

Hi,
I followed the instructions carefully and installed tesseract-ocr, libtesseract-dev, language pack and even the snap version but it still doesn't work. I am on Linux ubuntu 18.04.

I get the message processed for X cards when there are no imgs in the card but when there is an image I get the error : Could not find a valid Tesseract-OCR installation! Please visit the addon page in at https://ankiweb.net/shared/info/450181164 for install instructions

Can you tell me where I can find logs ? I have a decent chance of solving this myself if I can get them, to avoid bothering you.

Can you make it support .webp images?

I recently discovered you could update the dynamic shared libraries of tesseract with otool. All it takes is a simple shell script to change your installed tesseract into a standalone folder. I added it for my own app and thought it might help this project as well.

I think it can be useful to make the installation process easier for less techy users. Never used it though.

edit : just saw on reddit that you knew this already. The second link still stands though

Hi,

I have been thinking about doing an addon like this for a while. Congrats for doing this!

I had another approach though that you might find interesting.

I really didn't like the idea to add OCR fields to all the note types that can contain text so my idea was instead to add the text content as an HTML comment in the field containing the picture. Visually, it does not change a thing to the card and is searchable through the anki browser. I also mean you can restrict search per field, as sometimes my pictures are added in "sources" field or in "More", "Cloze body" etc.

I think this could be a very interesting feature to add. What do you think? It would be worth asking Damien if it is reasonnable to do or if comments are sometimes cleaned up or whatever.

Another possibility was to add the text content in the "alt" argument of the "img" html attribute, like in this example But I barely know HTML and have no idea what kind of issues this could create.

What do you think?

Either way the content would need to start with some kind of identifier like ___ocrtext_unixtime=23094203984209___ and ___endOCRtext___ to avoid adding text over and over in case someone runs the script regularly or wants to edit tesseract settings. At least that's how I designed it.

Hi, I frequently have this error message :

My OS is ubuntu 18, anki version is 2.1.35. I have the latest ankiOCR available for this anki version.

It happens without me understanding what kind of notes causes it. I had it with some text of my lesson that used weird characters (like the female and male thingie like ♂️ ) but it also happenned to random image occlusions.

Unfortunately, this error can happen after having ankiocr running through hundreds of cards in a row without saving the changes :/ So I have to redo it over and over again until I find the culprit cards.

Let me know if I can help you troubleshoot that :)

Hello! I have tried it a bit and always ran into a problem.

First, I tried OCR with many cards. I got a result window immediately. But no cards were OCRed. I could click the result window away. However, my cursor was still looking like an hourglass. It seems like Anki was suspended.
I could perform some actions, such as open the add-on window, edit an edit config.
I could not resume reviewing my cards. I could not close the browser. I could not close Anki normally.
After restarting Anki, I took a look in the browser and found out that no images had OCR results.

Later, I ran the add-on on only one card. This added the OCRed text to the note. But apart from that, it suspended Anki as in the other run.

Maybe it is because I use an older version of Anki.

Hi cfculhane,

I have some long Anki notes, and I think it will be very useful if when searching for a word in a card, it highlights the word or at least, bring the user to the image.

It may have to be combined with his shortcut
https://ankiweb.net/shared/info/225180905 ( Highlight Search results in browser)

• simply put highlight the word that you searched for as you press enter like what happens in a Microsoft document.

Image of an example of a highlighted word in the image ( done in Microsoft OneNote)

On the side note, your add on works prefectly otherwise in getting doing OCR. Thank you for taking the time to make such an amazing add on for the Anki community.

Kind regards,
Jeryl

The tooltip option if selected in config ,OCR works fine. But if i choose new_field , then this error comes.
I just want an easily copyable version of the text within the Image available in usual study window itself...Its difficult to go to browser each time i want to copy paste the title tooltip by opening HTML VIEWER.

A fatal error occurred, and Anki must close. Please report this message on the forums.

Hi,

I am an absolute fan of your addon and it became absolutely indispensable, thank you very much!

I regularly search my db for "<img -title" to scan new cards that don't have been OCR'd yet and was thinking that it would be useful to have it periodically check for that.

Say before synchronisation, a hook could be used to see if there is any non OCR'ed card. Just saying :)

Thanks again!

Hi!

I recently did a fresh ubuntu reinstall my ankiOCR install was not working. I fixed it apparently and wanted to share it here.

The error appeared when running the OCR command and was the following:

• Python 3.9.15 Qt 6.6.0 PyQt 6.6.0
• Windows 11 (2023)

Steps to replicate

1. Install from anki using the code provided in the AnkiWeb
2. Start Anki

Remarks

I know the error is simple to resolve but I think its better for the addon to install modules by themselves

a simple

pip install PyQt5

will fix it but I don't know if there would be more errors after that.

@cfculhane please look into it , this hasn't been updated in a long time.

我下载了"chi"语言包, 也更改了相关设置: 比如在eng后添加chi, 我还把chi包放到了tessdata文件夹中.
但不知为何不起作用, 并且不断报错.

您能简单的提示我一下吗,

谁能帮帮我. 我很需要这个插件, 我有很多的图像遮挡需要识别, 我面临着高考.
为此, 我也已经回退到支持这款插件的版本, 放弃了23.10 (我想让你了解, 我已经为此做出了很多努力, 也许只差''你回复我''这最后一步, 就能帮到我了!!)
