Image occlusions not working?

[Neill Alexander]

I have quite a few cards which I have created with the Anki desktop "Image Occlusion 2" add on. For some reason they are no longer working properly in Ankidroid. When the card comes up to study, previously the areas of the image were blanked out - on the desktop version they show up as red. But now in Ankidroid they are blanked out, but in white. So when I have more than one part of the image blocked out on a card, with a separate card for each blank, I can't tell which one that card relates to.

I've attached a demo which contains 2 cards. The full text reads "Assured Shorthold Tenancy Agreement". Card 1 has 'assured' blanked out. Card 2 has 'tenancy'. On the desktop version this works, on Ankidroid they are white. I've attached desktop versions, and screen grabs from my phone from Ankidroid.

Has something changed in the app? This used to work. I have a lot of cards in private decks which I have created in this way.

Any help would be appreciated.

you're like the 4th guy to ask about this, can you try searching the forum please

[Neill Alexander]

Well, that's embarrassing. I searched the other night but didn't find anything, but that was before I'd checked the name of the add on. Should have searched again for "image occlusion" I guess.

Apologies. Thanks for the response.

[Neill Alexander]

Just in case anyone wants to fix their "Image Occlusion" cards to work on Android 5.1, I've written a quick bash script to fix the svg tags. See the attached file.

You require 'zip' and 'unzip' to be available on the path for this to work. I ran it on Windows using Cygwin.

Export all your files to a directory, then run 'fix-anki.sh' from within that directory.

Use this at your own risk - make back ups first! The script does make backups of the files, but you should probably make your own backups to be sure.

If you export with all the schedule information, you can then delete the cards, re-import the updated version, and the image occlusion cards should now work.

[Neill Alexander]

And finally, if you go to https://github.com/mrestko/image-occlusion-2 and use the "Download zip" button, that person has merged in the fix for the svg. You can then replace the "Image Occlusion" add on in the add-ons directory with the fixed version. I've just tried it and it all works again.

Thanks for the script and tips! :-)

No problem. Thought I'd better add some value to the discussion after neglecting to do a basic search of the forum earlier ;-)

Hi Neill,

I've been trying to work around fixing my old occluded cards with your code but received the following error:

: command not found: 

: command not found: 

'ix-anki.sh: line 9: syntax error near unexpected token `do

'ix-anki.sh: line 9: `do

I also tried using the code provided by https://github.com/mrestko/image-occlusion-svg-fix and was also hit by an error:    

from lxml import etree

ImportError: No module named lxml

Think you could help me out?

[Tim]

"No module named lxml" most likely means exactly what it says...

Try installing that module into your python environment. For example using easy_install

[Tim]

It looks like the link I gave doesn't have any images included... 

If it's not much use you can try googling "easy_install windows tutorial" or something (assuming you're on Windows)...

You can also use pip instead of easy_install, it might be faster to get that working.

Hi Tim,

Managed to fix the Lxml issue thanks!

Now another problem came up:

Found 0 Image Occlusion files

Fixed 0 files

Even though I ran the script within the same directory.

Kindest Regards,

For me this script doesn't do anything. After executing it in cygwin it says:

MSSurface3Pro@DESKTOP-1B4PA4T /cygdrive/c/Users/MSSurface3Pro/Documents/Anki/Xequitep/collection.media

$ bash fix-anki.sh

fix-anki.sh: line 2: $'\r': command not found

fix-anki.sh: line 6: $'\r': command not found

fix-anki.sh: line 9: syntax error near unexpected token `$'do\r''

'ix-anki.sh: line 9: `do

Hi! How were you able to run the script with using that python command? I've been trying to search and find information for couple of hours about it, checking the Python manual and everything but I can't find out how to run those commands from python cmd. I've tried to use suggested commands, enabling stuff from installator and all but I can't just get it to work. I've hit "running cmd commands from Python" and "navigating to folders in Python" but I get nothing that works and I'm losing my mind.

So I have Python 3.4.3 installed now and I have the python file in my media.collection folder. Any easy instructions how to run that file with the python file from python cmd? Thanks for any help!

You saved the file with windows EOL terminators which includes newline "\n" and carriage return "\r". Save it as with unix EOL ("\n" only)

Hi Aloysius,

I'm at the same point and error message that you were. Did you ever figure out a solution?

Thanks,
