Have PDF with portrait mode as example of viewerjs.org (to show zooming tool)

[kossebau]

Current PDF examples on viewerjs.org all are in landscape mode, so ViewerJS assumes slides and goes to automatic zoom handling (i.e. full page and not showing the Zoom control).

Results in people wondering if zooming is supported at all also for PDF.

Hi, is it possible to enable zoom-controls in landscape PDF's? I need this when displaying CAD -drawings, they are usually in landscape, and contain a lot of detail, so zooming is a must here.

UPDATE:
Ok, I found solution, just change this line to return false: PDFViewerPlugin.js LINE 270

 this.isSlideshow = function () {
        return false;
    };

@generic-user right, this hack should give you what you need, well found :)

For the future there are plans to add a parameter mode or some more, so the UI of ViewerJS can be configured a little, as this automatic guessing about the nature of the PDF brings problems for too many, as your feedback showed by giving another good counter example.
