Image Occlusion Enhanced

1.05MB. Updated 2017-04-17. Only supports Anki 2.0.x.
The author has shared 62 other item(s).


     Image Occlusion Enhanced is an updated version of Image Occlusion 2.0. Image Occlusion lets you create cards that hide parts of an image to test your knowledge of that hidden information. The cards generated by this add-on would be best described as image-based cloze-deletions: COMPATIBILITY This version of Image Occlusion Enhanced only works with Anki's stable release branch (Anki 2.0.x, version 2.0.30 and up). If you are using Anki 2.1, make sure to check out the latest development release of the add-on, instead. CHANGES COMPARED TO IO 2.0 Here's a great overview by Med School Insiders on YouTube that goes over the key differences compared to older versions of IO. RELEASE LOG This section will always be updated with the latest changes to Image Occlusion Enhanced. More details on major releases are listed in the next section. For a full release log, including smaller bug fix releases and more details on each entry, make sure to check out the releases page on GitHub. 2017-04-17: v1.2.2 - Fixes a few smaller issues 2017-02-14: v1.2.0 - Usability improvements and under-the-hood changes 2016-01-14: v1.1.0 - New features, usability improvements, and bug fixes 2016-11-10: v1.0.0 - Ability to modify existing notes, among many other new features 2016-09-28: v0.3.0 - A large number of improvements to the Masks Editor 2016-04-03: v0.2.0 - Initial public release LATEST CHANGES AND NEWS 2018-06-30 An alpha version of Image Occlusion Enhanced for Anki 2.1 is now available here. 2017-04-17 A recent iOS-update might be affecting Image Occlusion 2.0 cards that were created earlier than 2015. If your occlusion masks are not drawn properly please use this supplementary add-on to fix them (thanks to mrestko for coming up with this solution). v1.2.2 INSTALLATION If you are starting from a fresh Anki installation you can simply follow the generic instructions listed below this add-on description. UPDATING Repeating the installation procedure will allow you to update to the latest release of the add-on. However, if you are upgrading from Image Occlusion 2.0 or early versions of Image Occlusion Enhanced please make sure to read the Wiki section on upgrading first. USAGE The use of this add-on is detailed in the Wiki and a series of video tutorials on YouTube. HELP AND SUPPORT Please do not use reviews for bug reports or support requests. I don't get notified of your reviews, and properly troubleshooting an issue through them is nearly impossible.

on 1615370935
Great work! I do have a question: is it possible to crop the image? I feel like that's such an easy, useful and popular tool that I was quite surprised when I can't find it. Or perhaps I'm just bad at technology, in which case can you give me instructions on how to crop images within the add-ons?

amazing, honestly changed my studying!

This is such a good complement for Anki, but please continue working on the issues. Recently I lost all my cards with image cloze (luckily I don't have many yet). It looks like it was due to a change in the name of the deck. I'm starting over, hope I don't lose them again.
Another problem is that I can't make it work on the Ankidroid.

I was so excited to discover this because it is exactly what I needed, but I can't get it to let me add more than 20 cards to a deck. Very frustrating!
Comment from author
Hi there. 20 cards is the default limit of new cards that Anki let's you study per day. You can change that by clicking on the gear icon next to the deck name and setting the "New cards/day" option to a higher value. Here's a quick 1 minute tutorial that shows this in action: https://www.youtube.com/watch?v=vUpdKZa3EBs

All of this is to say that the 20 cards don't have anything to do with Image Occlusion Enhanced. In light of that, would really appreciate it if you could reconsider your rating as it will otherwise be stuck here forever, and that's pretty frustrating.

Hi. I'm afraid there's not much I can do without knowing more about the error. As requested in the add-on description, please either submit a bug report on the issues tracker, create a thread on the Anki add-on support forms, or send me an email at ankiglutanimate@gmail.com. Otherwise I can't help you. Thanks!

Is it working on anki versions 2.1.12 -2.1.21 ?

on 1561756107
Very usefull for learning programming, it is a lot less of work to print screen and hide code than to recode every time the same thing.
Would be even better to hide image and make the possibility to write the answer (for coding parts)

Comment from author
If you submit a support request in the official support thread I might be able to help you: https://anki.tenderapp.com/discussions/add-ons/8295-image-occlusion-enhanced-official-thread. Right now there is not much I can to do with the information you've provided me with. Please add a post in the thread above, detailing what the issue is and adding more info about your Anki system, other add-ons you're using, etc.
2.0.52 is also at the end of its life, so you might want to try Anki 2.1 instead which comes with a better, updated version of Image Occlusion Enhanced: https://ankiweb.net/shared/info/1374772155. Obrigado.

Comment from author
The Anki 2.1 version is linked in the description: https://ankiweb.net/shared/info/1374772155. In the future please use the add-on list for Anki 2.1 to browse through add-ons: https://ankiweb.net/shared/addons/2.1

Also, I would appreciate if you removed that thumbs-down as it's unwarranted (and even if the add-on did not have a 2.1 version it would still not be warranted).
on 1554637722
This is an absolute game changer that truly opens up a new line of study. It should be a part of Anki. Incredible.

It doesn't work in 2.0.52 version. The image doesn't appear whenever import an one to. All that appears is a grayscale image of the editor background.
Comment from author
Please give the Anki 2.1 version a try: https://ankiweb.net/shared/info/1374772155

Image Occlusion on Anki 2.0 is known to have compatibility issues with non-latin locales (e.g. non-latin characters in the Anki installation or configuration path), resulting in a blank background when loading the editor. Cf. here: https://github.com/glutanimate/image-occlusion-enhanced/wiki/Troubleshooting#the-editor-wont-appear

It definitely can be called a masterpiece. I'll be your patron one day.

Thank you for the kind words! I really appreciate that :)
on 1551130006
Great for learning a ton of stuff. It would be nice to have the "hide all, show all" options versus the "hide all, show one" option. It can get tedious to delete the answer masks as seeing info lined up can be valuable.

Awesome!! Just discovered your amazing work and will definitely support you on Patreon. And to the person talking about Polar integration: +1! Considering the words you use I presume you are the developer.. I’m using TheBrain at the moment in combination with Anki, but would definitely swap to Polar if it has Image Occlusion Enhanced integrated!
on 1542569413
Love this add on. I'm considering embedding it directly into Polar so you can annotate books while you read them and then sync the flashcards directly to Anki.

In the meantime please see here for instructions on how to set up a custom Anki profile location: https://apps.ankiweb.net/docs/manual.html#startup-options. After this change, please also make sure that the images you are trying to import contain latin characters only (that is both in their file name, and in their full directory path on your hard drive).

I have a try and it does work.

If your your tracker jumps while making a rectangle.. it's probably your track pad and not anki....

Makes learning anatomy so much easier and faster
on 1525046400
While trying to draw a rectangle with my trackpad, the cursor jumps like crazy!!
Comment from author
Very sorry about that, but there's not much I can do about this since it's caused by bugs in the third-party component used to draw shapes (SVG-Edit). Touchpad compatibility will likely improve with Anki 2.1, but until then what I recommend you do is use an external mouse for the add-on, instead.

See here for more information: https://github.com/glutanimate/image-occlusion-enhanced/wiki/Troubleshooting#issues-with-touch-screens

Also, please don't report bugs in the review section. That's not what it's there for. Instead, please use the official bug tracker or support thread:

Comment from author
An alpha release for Anki 2.1 is available here now: https://ankiweb.net/shared/info/1374772155. But leaving a thumbs-down in the review section won't make development any faster. (Nor will it for any any of the other add-ons you left a thumbs-down on...).

Does not work with Anki.net or Anki.mobile, purchased a 25 dollar app to not be able to use my cards.
Comment from author
Sorry to hear that you weren't happy with your purchase. However, I have to point out that the cards generated by Image Occlusion do work across all Anki clients, AnkiWeb and AnkiMobile included. The only thing that doesn't work on other platforms is generating new cards. And that is simply because add-ons only run on desktop Anki.
on 1516924800

There's this bug that occurs each time I import an image to the editor. The image doesn't appear whenever import an one to. All that appears is a grayscale image of the editor background.
Comment from author
Thanks for the report. However, in the future please try reporting issues like this on the add-on's official bug tracker, instead: https://github.com/glutanimate/image-occlusion-enhanced. Alternatively, feel free to use the official support thread: https://anki.tenderapp.com/discussions/add-ons/8295-image-occlusion-enhanced-official-thread. I follow both and can be of much better assistance on either. (Not much we can do to troubleshoot the issue here). For what it's worth, this is likely caused by your Windows locale setting (cf. https://github.com/glutanimate/image-occlusion-enhanced/issues/47). I'm actively working on fixing the issue, although it's been difficult to track down so far.

Use it all the time! - Need a better way to edit old cards.

I love this addon, it saves lots of time introducing cards into the database. However, once its in the database - modifying the existing cards is quite difficult because you'll only see the occlusion objects.

A Bug:"Add Cards:Hide All,Reveal All"

This option has a bug. I choose three rectangles. I want to hide 3 on the front and shows the three on the back. Press this button to add 3 CARDS. This is a bug. It is wrong.
The three CARDS are the same. They are all hide 3 on the front and shows three on the back. The right should be add 1 card.

Image Occlusion Enhanced

Great ADD-ON
on 1495670400

A feature I’m really missing though is image import.
Sometimes I want to Import a whole list of blank images that I can edit later. But this is not possible because the hidden (id) is not generated.

perfect for me, great help to learn

Thank you very much for your work, I am very grateful to you
on 1486598400
It's a little clunky and takes a bit of thinking at first to understand how it works, and I think it has too many unnecessary fields that can't be deleted (I learnt that quickly. I had to restore them manually). So far, I'm using it for cards that show the order of some things, and it only makes sense to hide everything and reveal everything, and I only need one card for that. Since there's no way to draw 4 rectangles in one go, I get 4 or 5 cards created and then have to delete all the unnecessary ones. I wish there was an option to create just the single "hide all, reveal all" card.
on 1484697600
Great Addon

Really great addon. Just found it yesterday but I am sure I am going to use it a lot.

1 small improvement suggestion: I have a huge set of images where a question is at the top and the answer is at the bottom. I want to hide the answer to study.
As there are thousands of slides this takes a lot of effort to put into anki. The open new image from the edit screen definitely help. But applying the current setting to a batch of images would help a lot more. I could put all my slides into anki in a few seconds.
on 1479340800

Editing the previously made notes is the best part.
on 1476057600
in case youre getting SSL sync errors:

you need old image occlusion to properly sync your cards. then add this one on top. in order to install old image occlusion, you cant have image occlusion advanced.

i added anki onto a new computer when my old pc was only using the old image occlusion. you need old image occlusion to sync cards made with old image occlusion it seems.
on 1474502400
Great Update!

I gave up on image occlusion a while back. It was too buggy and caused more frustration than needed. This update solved all of my previous problems! Thank you!
on 1473120000
works great until it becomes extremely buggy

This is such a great part of anki. But more than half the time when I use this plugin it becomes extremely buggy. Random occlusion boxes start multiplying everywhere. It makes me restart the app multiply times until I can finally get it to work normally. But, again, when it does work normally it is great!

Should be included in the anki package

This add-on creates a whole new way of using Anki raising its value by a great margin.
on 1464134400
Really great but one feature needed

How do I edit the image while learning/reviewing? If I press edit on the card while reviewing, and then press the image occlusion button, it will open the editor. But any changes I make won't save to the card I'm reviewing. It will just create more notes if I press add ___ occlusion. How do I properly edit the card to remove shapes while reviewing?
on 1461283200

Hi, I love the changes you've made! For me, the biggest improvement is the "remarks" feature. I really like to add more info to come up below the image, once you've shown the answer. Is there any way to paste text or drag/drog a picture into the remarks field? I couldn't find a way to do so
on 1461110400
Image size

Great add-on.
In order to keep images in their original size while studying them (especially if you need to look at details), go to "browse" while viewing one of the occluded images, click on "Cards...", and add the following at the end of the "Styling" section:

img {max-width: none; max-height: none;}
