zoom in and zoom out is not working

[npapastefanakis]

i am trying to add in index.html the zoom in and zoom out button.

The code is:

<button id = "zoomIn" class = "toolbarButton zoomIn" title = "zoomIn"></button>
<button id = "zoomOut" class = "toolbarButton zoomOut" title = "zoomOut"></button>

It doesn't work.

Thanks

The viewer.js has a document.getElementById("download") in it. If we delete the element the script crashes and this is the reason it is not working.

Before add the event listener to the toolbar, I suggest to check if the element exists in the DOM. This way we can remove / add whatever button we need to show.

Kind regards (this was not an issue)

Nice work guys

How can I remove the download button ?

Hello!

If you wish to remove the download button from your copy of ViewerJS, you could simply add extra CSS to hide the element with ID "download".
