    Hi Luuk and Gemma,

    This looks like a great addition to Moodle. Could you share with us if it's possible to use the sketch game to let students draw in a preset?
    Simply set: The teacher uploads an image, the students then have to color inside the image to complete the task and submit their assignment (preferably from the online text editor).

    Kind regards,

    hi Menno

    The teacher can upload an image, the student should be able to use the coloring tools to color the image. The student kan use the option to make an export.
    Though we did not add an "submission" option in the module, but since they can download the image they could submit with the Moodle Assignment module.

    Does this answer your question?

    Hi Gemma,

    Thank you for your answer, it's much appreciated. It partly answers my question. The ''workaround'' would work for us, but the plugin only allows me to make circles, squares or arrows, I do not see a ''pencil''-function with which you could color a certain area on the image.
    Is this going to be available at some point?

    hi Menno,

    I forgot, indeed there is no pencil functionaliteit in de Canvas activity at the moment.
    Currently we only make sure that the plugin is supported in upcoming versions of Moodle, and don't have new functionalities added to the roadmap.

    That said, I am sure we can add this functionality, I will discuss it with Luuk as developer and will contact you privatly.

    Hi, This is great, our students use it to create posters, logos, notices. Could you add layering, so that items can be put on top? Also if you add a background after the main item it wipes it. Could more set shapes be added? Thank you.

    Please can you adjust the compatibility to 3.11 so it installs automatically upon upgrade? Cheers
