    is it possible that instead of changing the pages, scroll down the document?

    Sorry, at this time, it isn't. All is based on this system... But I will think about it.

    Is there any way to configure which file types will get converted by the cron? It looks like a video file has been processing for over 4 hrs.

    Hi Terry. The plugin does not do document conversion, but just sends them to a queue for processing by a document conversion service (see This is defined in Moodle admin under Site administration > Plugins > Document converters). I guess that depending on the converter selected the conversion behavior can change.

    is it possible to extend this plugin to include pictures (jpg, png). Many students take pictures of their handwritten assignment and upload those. Ghostscipt should be able to render pictures. Can it be done with this plugin as well?

    I found out that multiple entries of assignfeedback_editpdf was autogenerated whenever a student submit a image file or a teacher issues a image feedback file, the total filesize of the multiple assignfeedback_editpdf entries was about 4x - 5x the size of the actual uploaded file. we ran low disk space and decided to uninstall AnnotatePDF plugin so that all related data will be deleted as well, after uninstallation i run moosh file-delete --flush to immidiately emty the trashcan and its a success we recover about 50GB of disk space, but upon checking the mdl_files table, there's still 28GB assignfeedback_editpdf where filearea in ('tmp_jpg_to_pdf', 'stamps'). How can i properly removed this remaining data, so that deletion will be cascaded to all of its related data and no orphan records will be left?

    Hello Rodel,

    I'm experiencing the same problem. The assignfeedback_editpdf entries create lots of problems with storage. I tried uninstalling the plugin but still have thousands of orphan files which I cannot delete easily. Any ideas on this?

    Yes this plugin works alongside other Moodle features, such as marking guides and comments. Just check these as feedback options in the Moodle assignment preferences.

    @Rodel, @Napoleon,

    Could you bring this issue to the bug tracker? (link at top of this page) It will be easier to work things out from there.

    HI Marion Chardon, Nicolas Dunand
    The version of Moodle that I use is 3.10, and I have not been able to view the documents and neither the annotations, I would like to know if you have any solution?
