Hi Matthew, I'n sorry I was NOT clearer in my first message. Yes, the problem is the cleaning by the function format_text().
But that cleaning is there for a reason. Input from students, even form teachers, MUST be cleaned. People tend to copy-paste any type of things. We have had some incidents with teachers inadvertently pasting hidden malicious scripts, or just inconvenient advertisements.
A much better way to deal with the issue would be to store the image file in the editor draft filearea. But it's a significant more work, I understand.

@Enrique Castro Thanks again for the feedback. I have been looking into ways to do what you are requesting. However with the change I've submitted in MDL-59997, it would be strictly allowing only 3 mime types. I've search all over about security issues with Data URI and the only issues I've seen are with text mime types. So I've submitted it to Moodle with "possible" security questions, to see what they think.

Hi Matthew,
I have not altered the setup in any way. I was using Firefox as my browser.

@Rob Johnson I am running Moodle 3.3 with Adaptable 1.5, running Firefox. Still unable to recreate the issue. Please install the latest version of the plugin and let me know if it is still not working for you.

@Enrique Castro Both the tinymce and atto version of sketch now support uploading into the Moodle repo as normal Moodle images. Please test it out and see if it does what you hope. Latest version just released today. Version 2017090800

@Irith Herman Yes, there is a way to add additional features. http://literallycanvas.com/api/tools.html However I'm not sure how difficult a magic wand would be. I will look into it and see what would be involved. Thanks for the comment.

super! für smartphones und tabletts einfach der hit! hat kurz gedauert, bis ich kapiert hatte, dass man das icon bei den einstellungen vom editor noch hinzufügen muss (-: und im css vom template habe ich die höhe auf 95% gesetzt, sonst war auf dem ipad der button zum bestätigen außerhalb der anzeige ... jetzt hab ich viel spaß mit dem touchpen. eine nutzerin hat mir sogar gesagt, dass sie jetzt moodle nutzt, um ihre zeichnungen als bild zu speichern ...

nice,
it would be even better if you will be able to edit shapes and text (fixing, moving, resizing..) after placing them..

Hi not sure if it's here that i should ask or comment. Is it possible for to shift the "Insert Image" button that is currently at the bottom of the page to the top or to the side bar? Was using it on the phone and on a another small screen and everything works, but could not insert the image because the button was inaccessible. Possible? Any help?

I cannot see the controls once the frame opens and seem to be getting these errors and I am not sure how to fix. Thanks
