DocViewer: Full-Screen Option for Previews

This idea has been developed and deployed to Canvas

For document previews using the DocViewer tool, there really needs to be a full-screen option (this feature was available with the Box previewer). 

In addition to normal file previews, it would be great if the full-screen option was also available for students when they review the annotations on their submissions. Right now, when students review their submissions, they get a window-within-a-window view of their annotated submission. It would be a better user experience if they could throw that preview full-screen to review the feedback and comments from their teacher. Again, this feature was available for previews with the Box previewer.

Agreed! After spending hours providing notes and comments on submissions, students are having a really hard time seeing them because of the size of the window and comments overlapping each other. It would also be great for students to download an annotated file to make corrections easier.

Totally agree fabianm‌ and kkurzynski@sans.org‌. The window-within-a-window view and the inability to download an annotated file are real drawbacks from a student perspective but worse still staff are also reluctant to use a tool that makes it difficult for the students to read the feedback they have spent so much time providing.

I don't understand why we can no longer view files in fullscreen.

This is a serious issue. One that may not be as pressing as making changes to the functionality in speed grader but a needed fix none the less.
While we're at it perhaps we could change the default actions:https://community.canvaslms.com/ideas/6015-make-preview-the-document-the-default-action-for-linked-d...

With the Box previewer, you could also drag the bottom of the preview window to make it larger, which was a feature I used all the time. This feature is gone as well as the full-screen view. It's difficult to view a lot of documents with the default file preview window which looks about 3 inches tall even on a 27 inch screen.

A new document detailing some of the up-coming enhancements to DocViewer was just published this afternoon.  Check out #5 here: DocViewer Plan.

It's great that we can now view it in full screen but if I zoom in to the document in full screen mode I don't get scroll bars to move up and down the document, should I?

Community Member

Agreed. It loads the last page of content w/o scrolling as an option.

I would also like to see "resize js" used on the preview or at the minimum, a class added to the iframe container and iframe to allow our department to add this functionality.

r.morgan.1@bham.ac.uk‌ I just posted over on DocViewer Plan the same issue. 

So glad to see #5 & #6 updated!!

 

However, I am noticing that when I expand into full screen I am unable to scroll through the document and it centers it on the content (ie if it is a 5 page document all I see is page 3, if it is a 2 page doc, I see the bottom of the first page and the top of the second). I am on the phone with support now, but want to mention this in the community as well.

I haven't added yet, but we narrowed it down to only happening in Chrome. Firefox & Edge work as they should (I couldn't test Safari as we are a Windows shop).

Case #02181145 if anyone wants to add to it.

Great idea hensonj Nice Work !

Just have a class on the iframe would give those of us that can modify the CSS & JS files the ability to add the functionality.

I never have understood why everything in Canvas doesn't have some sort of class or id attached to it.
